MIC37502WU

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC37502WU is a Microchip Technology low-dropout (LDO) linear voltage regulator featuring a fixed 5.0V output and a 2.5A maximum continuous current capability. It utilizes the uCap technology, allowing stability with small ceramic capacitors. The device operates within an input voltage range of 3.0V to 6.0V and provides a typical dropout voltage of 550mV at full load. It includes integrated protection mechanisms such as overcurrent limiting and thermal shutdown. The component is housed in a compact SPAK-5 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.
