FAN1086D25X

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

The FAN1086D25X is a fixed positive low dropout linear regulator manufactured by Fairchild Semiconductor, now part of onsemi. It provides a stable 2.5V output with a maximum continuous current capability of 1.5A. The device utilizes a TO-252 (DPAK) surface-mount package to facilitate efficient thermal dissipation in compact designs. Key electrical characteristics include a typical line regulation of 0.05% and a load regulation of 0.4%. It incorporates internal protection mechanisms such as thermal limiting and current limiting to ensure reliability under overload conditions.
