AP7384-50V-A

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

The AP7384-50V-A is a positive voltage regulator IC from the Diodes Incorporated AP7384 series, designed for wide input voltage ranges up to 40V. It provides a fixed 5.0V output with a maximum current of 50mA. The device features low dropout voltage (500mV at 50mA), ultra-low quiescent current (2.5µA typical), and high output voltage accuracy within ±2%. It includes thermal shutdown and short-circuit protection functions. The component is housed in a TO-92 package with Ammo Packing and operates over a temperature range of -40°C to +125°C.
