AP7361EA-25SP-13

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

The AP7361EA-25SP-13 is a fixed-output linear regulator from Diodes Incorporated, providing a stable 2.5V output at up to 1A load current. It operates within an input voltage range of 2.2V to 6.0V and features an ultra-low dropout voltage of 340mV (typical) at full load. The device includes an active-high enable pin, low quiescent current of 68µA, and high power supply rejection ratio of 75dB. It is housed in an SO-8EP package with thermal protection.

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

Verify the specific suffix 'SP' corresponds to the SO-8EP package configuration. Confirm that the '13' suffix aligns with the required tape and reel quantity specifications for your manufacturing process. Ensure compatibility with RoHS 3 compliance requirements before finalizing procurement orders.

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

Select this component when a fixed 2.5V rail is required with high efficiency under moderate loads. The SO-8EP package offers improved thermal dissipation compared to smaller footprints. Consider the 68µA quiescent current for battery-powered applications where standby power consumption is critical.

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

This part belongs to the AP7361EA family of 1A low dropout regulators. Unlike the standard AP7361, the EA variant explicitly supports adjustable and fixed modes with an enable pin across multiple packages including U-DFN3030-8, SOT89-5, SOT223, TO252, and SO-8EP. It is designed for low-to-medium power applications requiring high PSRR and fast transient response.

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

Does the AP7361EA-25SP-13 support adjustable output voltage?

No, the '25' suffix indicates a fixed 2.5V output version. Adjustable versions use a blank space in the output code position.

What is the minimum output capacitance required for stability?

The datasheet recommends a minimum of 2.2µF ceramic capacitor on the output for stability, though 4.7µF is typically used in application circuits.
