AP7384-28SA-7

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

The AP7384-28SA-7 is a positive fixed-output low dropout regulator from the AP7384 series, manufactured by Diodes Incorporated. It provides a stable 2.8V output with a maximum continuous current of 50mA. The device supports an input voltage range from 3.3V to 40V and operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a typical dropout voltage of 500mV at full load, a ground current of 25µA at maximum output, and a power supply rejection ratio of 60dB. Line regulation is specified at 0.05%/V, while load regulation is 0.5%. The component is housed in a space-saving SOT-23-3 surface-mount package.
