STMICROELECTRONICS LD39015M18R Voltage Regulator

The LD39015 series is a low dropout voltage regulator designed for portable and battery-powered applications requiring up to 150 mA of output current. It operates over an input voltage range of 1.5 to 5.5 V, providing a typical dropout voltage of 80 mV at 100 mA load, and features ultra low noise without bypass capacitors. Its low quiescent current, low noise, thermal limit, short-circuit current limiting, and enable shutdown function make it ideal for mobile devices, PDAs, cordless phones, and other low power systems. It supports ceramic capacitors and operates across -40°C to 125°C.
