FAN1117AD25X Description

Short technical summary and product information.

The FAN1117AD25X is a low dropout linear voltage regulator manufactured by On Semiconductor, designed for applications requiring a stable 2.5V output at up to 1A.

 

This device offers features such as a low dropout voltage, trimmed current limit, and on-chip thermal limiting for protection. The quiescent current flows into the load, contributing to higher efficiency compared to PNP type regulators. It operates within a temperature range of 0°C to 125°C.

 

The FAN1117AD25X is supplied in a TO-252-3, DPak (2 Leads + Tab), SC-63 surface-mount package, making it suitable for various electronic designs where space is a consideration. Its fixed 2.5V output and 1A current capacity make it a reliable choice for power management in many electronic systems.

 

Key electrical characteristics include a maximum input voltage of 18V and a maximum voltage dropout of 1.2V at 1A. The regulator also provides a Power Supply Rejection Ratio (PSRR) of 72dB at 120Hz.
