FAN2502S30X

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

The FAN2502S30X is a micropower low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides a fixed output voltage of 3.0V with a maximum continuous output current of 150mA and a peak current capability of 300mA. The device operates within an input voltage range of 2.7V to 6.5V, featuring a typical dropout voltage of 150mV at full load. It incorporates CMOS technology for ultra-low power consumption, drawing only 25µA of ground current during operation. The component includes thermal limiting protection and an enable/shutdown control pin that reduces quiescent current to less than 1µA when disabled.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'S30X' to confirm the fixed 3.0V output configuration and bypass pin function. Ensure the ordering quantity aligns with the standard tape and reel packaging size of 3,000 units per reel. Confirm compatibility with the required PCB footprint for the SOT-23-5 package before finalizing procurement decisions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring a stable 3.0V rail from a single-cell lithium-ion or alkaline battery source. The wide tolerance for external capacitor ESR values simplifies bill-of-materials selection. Consider the thermal resistance characteristics of the SOT-23-5 package when designing for high ambient temperatures or sustained maximum load currents.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the FAN2502/03 family of 150mA CMOS LDO regulators. The FAN2502 variant distinguishes itself through Pin 4 functionality, which serves as a bypass pin for noise reduction in fixed-voltage versions like the S30X. This family offers improvements over older BiCMOS designs, providing better loop stability and lower dropout voltages.
