AP7344D-3330RH4-7

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

The AP7344D-3330RH4-7 is a dual-channel low-dropout regulator manufactured by Diodes Incorporated. It provides fixed output voltages of 3.3V on Channel 1 and 3.0V on Channel 2, with a guaranteed continuous output current of 300mA per channel. The device operates within an input voltage range of 1.7V to 5.25V and maintains an output voltage accuracy of ±1% at +25°C. Key electrical characteristics include a typical ripple rejection ratio of 75dB at 1kHz and a low output noise of 60µVrms across the 10Hz to 100kHz bandwidth. Quiescent current is specified as low as 50µA when one channel is active. The component utilizes an X2-DFN1612-8 package and supports an operating temperature range from -40°C to +85°C.

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

Verify that the specific ordering suffix matches the required output discharge configuration, as the 'D' suffix indicates built-in auto-discharge functionality. Confirm the package type corresponds to the X2-DFN1612-8 form factor. Ensure compatibility with RoHS compliance standards if applicable to your manufacturing process. Check for any specific handling requirements related to moisture sensitivity levels before assembly.

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

Select this component when dual isolated rails are required within a single small package. The 300mA current rating supports moderate load demands. Consider the dropout voltage specifications relative to your minimum input voltage to ensure regulation stability under full load conditions. Evaluate the thermal dissipation capabilities of the PCB layout against the expected power loss during operation.

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

This part belongs to the AP7344 series of dual LDO regulators designed for handheld communication equipment. It is based on a CMOS process technology.
