General Specifications
   IC Package Type       
   Your choices are...         
   DIP / CDIP / PDIP       Dual in-line package (DIP) is a type of DRAM component packaging. DIPs can be installed either in sockets or permanently soldered into holes extending into the surface of the printed circuit board. Ceramic dual in-line package (CDIP) consists of two pieces of dry pressed ceramic surrounding a "DIP formed" lead frame. The ceramic / LF / ceramic system is held together hermetically by frit glass reflowed at temperatures between 400° - 460° centigrade. Plastic dual in-line package (PDIP) is widely used for low cost, hand-insertion applications including consumer products, automotive devices, logic, memory ICs, micro-controllers, logic and power ICs, video controllers, commercial electronics, and telecommunications. 
   DPAK (TO-252)       Discrete package or deca-watt (DPAK). 
   PPAK (QFN-16)       Power packaging (PPAK). 
   QFP       Quad flat packages (QFP) contain a large number of fine, flexible, gull wing shaped leads. Lead width can be as small as 0.16 mm. Lead pitch is 0.4 mm. QFPs provide good second-level reliability and are used in processors, controllers, ASICs, DSPs, gate arrays, logic, memory ICs, PC chipsets, and other applications. 
   SC-70       SC-70 is one of the smallest available IC packages. It is used in cellular phones, PDAs, electronic games, laptops, and other portable and hand-held applications where space is extremely limited. 
   SO-8       Small outline (SO) package with 8 pins. 
   SO-14       Small outline (SO) package with 14 pins. 
   SO-20       Small outline (SO) package with 20 pins.  
   SSOP       Shrink small outline package (SSOP). 
   SOIC / SOP       Small outline integrated circuit (SOIC). Small outline package (SOP). 
   SOJ       Small outline J-lead (SOJ) is a common form of surface-mount DRAM packaging. It is a rectangular package with J-shaped leads on the two long sides of the device. 
   SOT23       SOT23 is a rectangular, surface mounted, small outline transistor (SOT) package with three or more gull wing leads. SOT23 features a very small footprint and is optimized for the highest possible current. Because of its low cost and low profile, SOT23 is used in home appliances, office and industrial equipment, personal computers, printers, and communication equipment. 
   SOT89       SOT89 is a plastic, surface mounted, small outline transistor (SOT) package with three leads and a collector pad for good heat transfer. Unlike other packages, SOT89 lead posts are up-set and not down-set. SOT89 is designed for medium power and high-speed switching applications. It is also used in applications that feature very low RDS (on), no secondary breakdown, and direct interface to complementary metal oxide semiconductor (CMOS) and transistor-transistor logic (TTL). 
   TO-3       TO-3 is a transistor outline (TO) package with three leads. 
   TO-39       TO-39 is a transistor outline (TO) package. 
   TO-92       TO-92 is a single in-line, transistor outline (TO) package that is often used for low power devices. One of the oldest power packages, TO-92 is suitable for applications in office and communication equipment. 
   TO-220       TO-220 is a transistor outline (TO) package that is suitable for high power, medium current, and fast-switching power devices. TO-220 is used in home appliances, office and industrial equipment, and personal and consumer electronics. A package variant, TO-220 Full Pack, includes a fully encapsulated heat sink that does not require extra hardware for electrical isolation. TO-220 Full Pack has the same footprint as TO-220, provides electrical isolation up to 5 KV, and is often used in motor drive applications and power supplies. 
   TO-263       TO-263 is the surface-mount version of the TO-220 package. TO-263 is a transistor outline (TO) package with 2, 3, 5, 6, or 7 leads. TO-263 can accommodate large dice because of its large pad design. It is suitable for high power applications due to its low resistance. Typical applications for TO-263 include home appliances and personal computers.

   Configuration / Function       
   Your choices are...         
   Step-down (Buck)       Buck or step-down converters are used to convert a higher DC input voltage to a lower DC output voltage of the same polarity. Using a transistor as a switch, buck converters alternately connect and disconnect the input voltage to an inductor. 
   Step-up (Boost)       Boost or step-up converters are used to convert a lower DC input voltage to a higher DC output voltage of the same polarity. 
   Inverting Regulator (Buck-Boost)       Buck-boost converters can be used for either step-up or step-down conversions. They can also be used to reverse or invert voltage polarity. With buck-boost converters, the inverting regulator converts a DC input voltage to a DC output voltage that is opposite in polarity to the input. The negative output voltage can be either larger or smaller in magnitude than the input voltage. Buck-boost converters work by storing energy in an inductor during the ON phase and releasing it to the output during the OFF phase. 
   CUK       CUK converters use capacitive energy transfer. The input and output inductors create a smooth current at both sides of the converter. By contrast, buck, boost, and buck-boost converters have at least one side with pulsed current. The CUK converter is named after its originator, Slobodan Cuk, of Cal Tech University. 
   Flyback Converter       Flyback converters are similar to buck-boost converters, but use a transformer to store energy and provide isolation between the input and output. With transformers, energy storage occurs through the magnetization of the transformer core. 
   Forward Converter       Forward converters are similar to buck-boost converters, but use a transformer to store energy and provide isolation between the input and output. The difference between flyback and forward converters is in the way in which transformers are used. Flyback converters have two distinct phases for energy storage and delivery. By contrast, forward converters use transformers in a more traditional manner, transferring energy from input to output in a single step.

Features
           
   Your choices are...         
   Shutdown (Inhibit) Pin       Shutdown (inhibit) pins are used to disable the regulator outputs. 
   Reverse Voltage Protection       This feature prevents damage to the regulator when the input voltage is reversed. It is essential in applications where a user can accidentally reverse the polarity of the batteries, or make similar mistakes. 
   Error Flag       This flag is used to alert monitoring or control circuitry that the output has dropped (generally 5%) below its nominal value. 
   Internal Current Limit       Regulators have an internal circuit to control the amount of current produced. 
   Input Overcurrent Protection       Regulators have an internal circuit that protects it when an excessive input current is applied. 
   Thermal Shutdown Protection       Regulators have an embedded control circuit that shuts down the device when the temperature exceeds a predefined limit. 
   Multiple Outputs       Regulators have more than one output (channel). 
   Synchronous Rectification       For switching, converters used metal-oxide silicone field-effect transistors (MOSFET) instead of diodes. Synchronous rectification means that the MOSFETs are turned on and off at the right time for efficient gating or rectification of the output. 
   Other       Other unlisted features. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
