FAN2514S28X

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

The FAN2514S28X is a fixed-output low-dropout linear regulator from the FAN2514/15 family, manufactured by onsemi. It provides a regulated output voltage of 2.8V with a maximum continuous output current of 200mA and supports peak currents up to 300mA. The device operates within an input voltage range of 2.7V to 6.5V and features a dropout voltage of 200mV at full load. It utilizes CMOS technology to achieve a ground pin current of 75µA at 200mA output. The component includes thermal limiting protection and an enable/shutdown control function that reduces shutdown current to less than 1µA.
