AP7370-15Y-13

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

The AP7370-15Y-13 is a positive voltage regulator IC from Diodes Incorporated, featuring a wide input voltage range of 3.2V to 18V and a fixed output voltage of 1.5V. It provides an output current capability of 300mA with a maximum dropout voltage of 500mV at 100mA load. The device operates within a junction temperature range of -40°C to +125°C and includes thermal shutdown, short-circuit protection, and reverse current protection. Packaged in SOT-89, it utilizes a 13-inch tape and reel for surface-mount assembly.
