FAN1086D285X

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

The FAN1086D285X is a positive fixed linear regulator from the FAN1086 family, manufactured by onsemi. It provides a fixed output voltage of 2.85 V with a maximum output current capability of 1.5 A. The device utilizes a TO-252AA (DPAK) surface-mount package and operates within an ambient temperature range of 25°C to 125°C. Key electrical specifications include a maximum input voltage of 7.5 V, a typical dropout voltage of 1.5 V at full load, and a power supply rejection ratio (PSRR) of 72 dB at 120 Hz. The component integrates overcurrent and thermal shutdown protection mechanisms.
