AP7361C-12FGE-7

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

The AP7361C-12FGE-7 is a fixed-output linear regulator providing 1.2V at up to 1A output current, housed in an 8-pin U-DFN3030-8 package with exposed pad. It operates within a 2.2V to 6.0V input voltage range and maintains ±1% output voltage accuracy. The device features ultra-low dropout characteristics, typically 540mV at 1A load, and consumes approximately 60µA of quiescent current. It includes built-in current limit protection (1.5A typical) and thermal shutdown for fault conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low dropout performance ensures stable regulation even when the input voltage closely approaches the output level.
• Integrated enable pin allows precise power management control by switching the regulator on or off via logic signals.
• Built-in thermal shutdown and fold-back short circuit protection safeguard the component against overheating and overcurrent events.

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

• Portable electronic devices requiring efficient battery-powered voltage regulation
• Audio and video equipment needing low-noise power supplies
• Laptop computers utilizing multiple regulated voltage rails

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

Verify that the specific part number matches the required fixed 1.2V output configuration and the U-DFN3030-8 package type. Confirm compliance with RoHS and REACH directives as specified in the manufacturer documentation. Ensure the ordering suffix corresponds to the correct tape and reel packaging quantity before finalizing procurement orders.

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

Select this component when a fixed 1.2V rail is required with high efficiency under varying load conditions. The low quiescent current makes it suitable for battery-operated systems where standby power consumption must be minimized. Verify that the maximum power dissipation capabilities of the U-DFN3030-8 package can handle the expected thermal load based on the input-to-output voltage differential.

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

This device belongs to the AP7361C series of low dropout regulators manufactured by Diodes Incorporated. The series offers both adjustable and fixed output options across various packages including SOT89-5, SOT223, and SO-8EP. The AP7361C-12FGE-7 specifically denotes the 1.2V fixed version in the compact U-DFN3030-8 footprint designed for space-constrained PCB layouts.

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

AP7361C-12E-13 provides the same 1.2V fixed output but utilizes a SOT223 package instead of U-DFN3030-8.
