FAN1582MX

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

The FAN1582MX is a low-dropout linear voltage regulator manufactured by onsemi, housed in a TO-263-5 surface-mount package. It provides an adjustable positive output voltage ranging from 1.3 V to 5.7 V with a maximum continuous output current of 3 A. The device operates within an input voltage range of 1.75 V to 6.5 V and features a typical dropout voltage of 1.05 V, with a maximum of 1.18 V at full load. Line regulation is specified at 3 mV, and load regulation at 5 mV. It includes thermal shutdown and overcurrent protection, operating reliably across a temperature range of -65°C to +125°C.
