FAN2502S30X

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

The FAN2502S30X is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a fixed 3.0V output with a maximum continuous load current of 150mA. The device operates from an input voltage range of 2.7V to 6.5V and features a typical dropout voltage of 200mV at full load. It includes internal protection mechanisms such as thermal shutdown and current limiting. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation over an extended temperature range of -40°C to +125°C.
