AP7361E-28FGE-7

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

The AP7361E-28FGE-7 is a fixed-output linear regulator manufactured by Diodes Incorporated. It provides a regulated output voltage of 2.8V with a maximum continuous output current of 1A. The device operates within an input voltage range of 2.2V to 6.0V and features a typical dropout voltage of 340mV at full load. Key electrical parameters include a quiescent current of 60µA, power supply rejection ratio (PSRR) of 75dB at 1kHz, and output voltage accuracy of ±1%. Integrated protections include current limiting at 1.5A, fold-back short circuit protection at 400mA, and thermal shutdown at +150°C.

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

Verify the specific ordering suffix '28' confirms the fixed 2.8V output configuration. Confirm the package code 'FGE' matches the required U-DFN3030-8 (Type E) footprint. Ensure the reel quantity suffix '7' aligns with standard tape and reel specifications. Cross-reference the datasheet revision against manufacturing dates to ensure component availability and compliance status.

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

Select this component when a precise 2.8V rail is required from a 2.2V to 6.0V source. The integrated PG pin makes it suitable for systems requiring supply sequencing or status indication. Consider the low quiescent current for battery-powered designs. Verify that the thermal dissipation requirements fit within the U-DFN3030-8 package constraints for the target ambient temperature.
