  • Startup Voltage Tracking With MSK5910RH and 5922RH Low Dropout Radiation Hardened Regulators
    The MSK5910RH and MSK5922RH are 5A, radiation hardened, low dropout regulators. with input to output voltage tracking capability. Many FPGAs require a logic power. supply that is greater than the core voltage. Additionally the logic power supply often. cannot exceed the core voltage
  • The lowdown on lowdropout regulators
    Voltage regulators that maintain output control almost to the supply rail operate cooler and increase efficiency. Low-dropout regulators like this MCP1726 from Microchip Technology create a self-contained power regulator for embedded microprocessors. The MCP1726 maintains regulation within 150 mV
  • DC Performance Comparisons of CMOS vs Bipolar LDOs When Operating in "Dropout" (Vin = Nominal Vout) Mode (list devices)
    battery for their power source. Digital cameras contain high-speed memory ICs, which require tight voltage regulation at moderate loads to meet the required timing parameters of the system. Precision low dropout (LDO) regulator devices can be used to meet these requirements but in doing so, the LDO
  • DC/DC Conversion
    additional features: over-current protection, thermal protection and reversed polarity protection to name a few. Microchip offers a line of CMOS, low dropout linear regulators. A low dropout regulator is a type of linear regulator designed to minimize the saturation voltage of the output transistor
  • Pin-Compatible CMOS Upgrades to Bipolar LDOs
    Bipolar low dropout regulators (LDOs) have become common place in a variety of portable applications, such as cell phones, pagers and PDAs. Their popularity stems from small packaging, high output current capability and precision output voltage specifications. However, the bipolar process
  • LDO Thermal Considerations
    with very low input/output voltage differentials, hence the name "low dropout regulators" or LDOs. LDOs specify maximum output current and input voltage limits, but blindly operating the LDO within these limits will surely result in exceeding the maximum power dissipation capability.
  • MCP1701 vs MCP1701A vs MCP1702 Technical Brief
    the initial release of the MCP1701 2 µA Low 150°C. The LDO will remain shutdown until the junction Dropout Positive Voltage Regulator, Microchip temperature has cooled to the typical turn-on junction Technology Inc. has been addressing customer temperature of 130°C. At that point, the LDO will turn
  • Ripple and Noise Measurements with DC/DC Switch-Mode Power Supplies
    are recommended for the low noise levels typical found with non-switching low dropout linear reg. ulators (LDGs). The measurement examples will focus on SMPS buck (step-dawn) low voltage regulators.
