FAN2515S33X

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

The FAN2515S33X is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a stable 3.3 V output with a maximum load current of 200 mA. The device operates within an input voltage range up to 6.5 V and features a typical dropout voltage of 200 mV at full load. It is housed in a compact SOT-23-5 surface-mount package. The regulator supports an enable pin for power management and includes internal protection mechanisms against overcurrent and thermal overload.
