AN80M27RSP

Overview

The AN80M27RSP is a 5-pin low dropout voltage regulator IC with standby function, delivering up to 0.5 A output current. It features a typical dropout voltage of 0.25 V and an output voltage accuracy of ±3%. The device operates within a supply voltage range of 3.2 V to 14.0 V. Standby consumption current is limited to a maximum of 3 µA. Ripple rejection ratio reaches 30 dB at 500 kHz. Output noise voltage is typically 40 µV. Overheat protection activates at a junction temperature of 150 °C.

Feature Summary

• Integrated standby function for minimizing power consumption during non-operation
• Low dropout characteristic enabling efficient regulation near input limits
• Built-in thermal protection and overcurrent limiting for circuit safety

Applications

• General use power supply circuits

Procurement Notes

Verify the specific part number against official Panasonic datasheets before procurement. Confirm package type compatibility and ensure operating conditions remain within absolute maximum ratings. Check for lead-free package updates if required by design specifications. Validate component suitability for the intended application environment.

Selection Notes

Select this regulator when low quiescent current in standby mode is critical. Ensure input voltage stays above the minimum dropout threshold for the desired load. Consider thermal management as power dissipation increases with higher load currents or larger input-output differentials. Verify noise requirements align with the specified ripple rejection capabilities.

Part Context

This component belongs to the AN80MxxRSP series of low dropout regulators. The series offers various fixed output voltages ranging from 1.8 V to 5.3 V. All variants share similar electrical characteristics and packaging, differing primarily in their regulated output levels. The SP-5SU package provides surface mounting convenience.
