General Description

The MIC5237 is a general-purpose low-dropout regulator capable of 500mA output current with better than 3% output voltage accuracy. Using Micrel’s proprietary Super ßeta PNP® process with a PNP pass element, these regulators feature less than 300mV dropout voltage and typically 8mA ground current at full load.

Features

• Guaranteed 500mA output over the full operating temperature range
