FAN1582D25X

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

The FAN1582D25X is a positive fixed linear voltage regulator IC from onsemi, delivering a maximum output current of 3A. It provides a fixed output voltage of 2.5V with a maximum input voltage rating of 7V. The device features a typical quiescent current of 6 mA and offers a power supply rejection ratio (PSRR) of 80dB at 120Hz. It operates within an ambient temperature range of -65°C to 150°C and includes overcurrent and overtemperature protection. Packaged in a TO-252-5 (DPAK) surface-mount case, it has a maximum dropout voltage of 1.18V at full load.
