FAN2500S285X

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

The FAN2500S285X is a micropower low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It utilizes CMOS technology to provide a fixed positive output voltage of 2.85 V with a maximum output current of 100 mA. The device operates within an input voltage range of 2.7 V to 6.5 V and features a typical dropout voltage of 2.5 mV at full load. It offers high line regulation of 0.3% per volt and load regulation of 2%. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation over an extended temperature range from -40°C to +125°C.
