FAN2514SX

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

The FAN2514SX is a fixed-output low-dropout (LDO) voltage regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a 3.0 V output with a maximum load current of 200 mA. The device utilizes CMOS technology and features a fast start-up capability enabled by an external capacitor or internal circuitry. It operates within an input voltage range up to 6.5 V and maintains regulation across a junction temperature range of -40°C to +125°C. The regulator is housed in a compact SOT-23-5 surface-mount package, designed for space-constrained applications requiring stable power delivery.
