AP7361C-33Y5-13

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

The AP7361C-33Y5-13 is a fixed-output 3.3V, 1A low dropout linear regulator manufactured by Diodes Incorporated in the SOT89-5 package. It operates with an input voltage range of 2.2V to 6.0V and features a typical quiescent current of 60µA. The device provides high power supply rejection ratio (PSRR) of 75dB at 1kHz and includes built-in current limit, thermal shutdown, and fold-back short circuit protection. Output voltage accuracy is maintained within ±1%.

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

What is the minimum output capacitor value required for stability?

The AP7361C requires a minimum output capacitance of 2.2µF ceramic capacitor to ensure stability and improve transient response.

How does the enable pin function on this device?

The EN pin is active-high; setting it to a logic high level turns the regulator on, while pulling it low disables the output.
