FAN1086M25X

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

The FAN1086M25X is a fixed-output low dropout linear regulator manufactured by onsemi, providing a stable 2.5 V output with a maximum continuous current of 1.5 A. It operates within an input voltage range up to 7.5 V and features a typical dropout voltage of 1.3 V at full load. The device incorporates internal thermal limiting and trimmed current limit protection for robust operation. It is housed in a D2PAK-3 (TO-263-3) surface-mount package and supports an operating temperature range from 0°C to +125°C.
