MIC5524 - High-Performance 500mA LDO

Description

The MIC5524 is a low-power, µCap, low dropout regulator designed for optimal performance in a very-small footprint.

It is capable of sourcing 500mA of output current and only draws 38µA of operating current to do so.

Features

  • Input voltage range: 2.5V to 5.5V Fixed output voltages down to 1.0V 500mA guaranteed output current High output initial accuracy (±1%) High PSRR 80dB Low quiescent current 38µA Stable with 2.2µF ceramic output capacitors Low dropout voltage 260mV @ 500mA Auto discharge and internal enable pulldown Thermal-shutdown and current-limit protection 4-pin 1mm x 1mm Thin DFN package Applicatio.

MIC5524 High-Performance 500mA LDO in Thin DFN Package General Description The MIC5524 is a low-power, µCap, low dropout regulator designed for optimal performance in a very-small footprint. It is capable of sourcing 500mA of output current and only draws 38µA of operating current to do so. The MIC5524 includes an auto-discharge feature on the output that is activated when the enable pin is low and it has an internal pull down resistor on the enable pin that will disable the output when the enable pin is left floating, this is ideal for applications where the control signal is floating during processor boot up. This high-performance LDO offers fast transient response and good PSRR in a 1mm × 1mm Thin (0.4mm ht.) DFN package.
