AP7344D-2833RH4-7

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

The AP7344D-2833RH4-7 is a dual-channel low-dropout regulator from Diodes Incorporated, housed in an X2-DFN1612-8 package. It provides fixed output voltages of 2.8V on Channel 1 and 3.3V on Channel 2. The device guarantees a continuous output current of 300mA per channel with a wide input voltage range of 1.7V to 5.25V. Key electrical characteristics include ±1% output accuracy at +25°C, 75dB ripple rejection at 1kHz, and 60µVrms output noise. Quiescent current is 50µA when one channel is active, dropping to 0.1µA in standby.

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

Verify the component status before procurement as the datasheet explicitly states the AP7344 series is not recommended for new designs. Confirm that the specific ordering suffix matches the required output discharge configuration and packaging format. Ensure compatibility with existing board layouts due to the small X2-DFN1612-8 package dimensions.

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

Select this component for applications requiring two distinct regulated rails within a minimal space constraint. The dual-channel architecture allows for synchronized or independent operation via dedicated enable inputs. Consider the dropout voltage characteristics relative to the minimum input voltage to ensure stable regulation under maximum load conditions.
