FAN2511S285X

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

The FAN2511S285X is a low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides a fixed positive output voltage of 2.85 V with a maximum output current of 100 mA. The device is housed in a SOT-23-5 surface-mount package and operates within an ambient temperature range of -40°C to +125°C. Key electrical specifications include a maximum dropout voltage of 180 mV at full load, a quiescent current of 50 µA, and a power supply rejection ratio (PSRR) of 43 dB at 120 Hz. The input voltage range extends up to a maximum of 6.5 V.
