General Specifications
   Regulator Type       
   Your choices are...         
   Standard       Standard voltage regulators have an NPN-Darlington configuration for the pass device. In order to maintain output regulation, the pass transistor requires a minimum voltage. For a standard regulator, the voltage where the output falls out of regulation (called the drop out voltage) is between 1.5 V and 2.2 V. 
   Low Dropout (LDO)       Low-dropout (LDO) regulators differ from standard regulators in that the pass device consists of a single PNP transistor. The minimum voltage drop required across the LDO is the voltage across the PNP transistor. LDO regulators have the lowest dropout voltage specifications of the three regulator types. Dropout voltages as high as 1 V have been called LDO, but a more typical value is between 100 mV and 300 mV. 
   Quasi-LDO       Quasi-LDO regulators are similar to Standard regulators, but use NPN and PNP transistors as the pass device. A quasi-LDO regulator has a dropout voltage that is higher than a LDO, but lower than a Standard regulator.

Performance
   Regulated Output Voltage (Volt)       The output regulated voltage (Volt) represents minimum and maximum amounts in continuous mode (DC). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Output Current (IOUT)       The output current (IOUT) is measured under specified conditions. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Volt Tolerance       The tolerance in plus and minus values of the principal output voltage or in the given range. The guarantee (in percentage) that the regulated output voltage will remain within a certain percentage. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Input Voltage (VIN)       The input voltage (VIN) is in continuous mode (DC) in accordance with minimum and maximum levels that can be applied to the integrated circuit (IC). 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Dropout Voltage (VD)       The dropout voltage is the minimum voltage drop across the regulator to maintain output voltage regulation. It is important to know that a voltage regulator that operates with smallest voltage across it dissipates the least internal power and has the highest efficiency. The LDO type requires the least voltage across it, while the standard type requires the most. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Quiescent Current (IQ)       Quiescent current (IQ) is measured in amperes (A) during the idling state. Quiescent current is also called operating current or ground current. Quiescent current never makes it to the load, but flows from the battery to power the regulator itself. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Operating Temperature:       This is the ambient temperature range through which the device is designed to operate. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
