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

Select this component for applications requiring stable 3.3V regulation from battery sources or single-cell supplies. The device is suitable where space constraints necessitate the SOT-23-5 package. Consider the thermal resistance characteristics when designing for high ambient temperatures or heavy loads to ensure junction temperature limits are not exceeded.

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

This part belongs to the FAN2504/05 family of 200mA CMOS LDO regulators. The 'XX' suffix indicates a fixed output voltage variant, specifically 3.3V in this instance. Pin 4 serves as a bypass connection for noise reduction, distinguishing it from adjustable or error-flag versions within the same series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official datasheets for cross-reference data. Verify pinout compatibility, particularly regarding the Bypass function on Pin 4, when evaluating alternative regulators.
