Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for FAN2509S30X

FAN2509S30X

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

The FAN2509S30X is a micropower low-dropout (LDO) linear voltage regulator from the FAN2508/09 family, manufactured by onsemi. It provides a fixed 3.0V output with a maximum load current of 50 mA. The device utilizes CMOS technology to achieve ultra-low power consumption, featuring a ground pin current of 25 µA at full load and less than 1 µA in shutdown mode. It operates within an input voltage range of 2.7 V to 6.5 V and offers a typical dropout voltage of 50 mV at 50 mA. The component includes thermal limiting protection and an error flag output.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Integrated error flag output indicates when the regulated voltage drops below 95% of the nominal value due to faults such as input dropout or overheating.
Ultra-low quiescent current design minimizes power consumption, reducing supply current to less than 1 µA when disabled via the control pin.
Robust loop stability accommodates a wide variety of external capacitors with varying ESR values, simplifying circuit design.
