FAN2514SX

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

The FAN2514SX is a micropower low-dropout (LDO) voltage regulator manufactured by onsemi. It utilizes CMOS technology to deliver a continuous output current of 200 mA with a peak capability of 300 mA. The device features an adjustable output voltage range from 1.8 V to near the input voltage, determined by an external resistor divider connected to the ADJ pin. It operates within an input voltage range of 2.7 V to 6.5 V and maintains a maximum dropout voltage of 200 mV at full load. The regulator includes thermal limiting protection and an enable/shutdown control function that reduces ground current to less than 1 µA.
