AP7343-10W5-7

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

The AP7343-10W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 1.0V with a guaranteed maximum load current of 300mA. It operates within an input voltage range of 1.7V to 5.25V and features high power supply rejection ratio (PSRR) of 75dB at 1kHz alongside low output noise of 60µVrms from 10Hz to 100kHz. The device utilizes a CMOS process for low quiescent current consumption of 35µA and includes integrated thermal shutdown and current limit protection. It is housed in a surface-mount SOT-25 package suitable for dense PCB layouts.

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

Verify the specific ordering suffix W5 confirms the SOT-25 package configuration required for your assembly process. Ensure the non-discharge variant matches your system's power-down requirements, as discharge versions exist within the same family. Confirm RoHS compliance status aligns with your manufacturing standards before finalizing procurement orders.

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

Select this component when a fixed 1.0V rail is needed with minimal footprint constraints. The SOT-25 package offers a compact solution compared to larger regulators. Consider the 300mA current limit sufficient for your peak load demands. Verify that the input voltage remains above the dropout threshold across all operating temperatures to maintain regulation accuracy.

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

This part belongs to the AP7343 series of low dropout regulators designed for low-power handheld communication equipment. The series provides various fixed output voltages ranging from 0.9V to 3.6V. It is distinct from the automotive-compliant AP7343Q variant, which carries separate qualification standards. The standard commercial version focuses on cost-effective integration into consumer electronics.

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

AP7343D-10W5-7 serves as a direct substitute if output discharge functionality is required instead of the non-discharge feature found in the base model. Other voltage variants within the AP7343 series share identical pinouts and electrical characteristics but provide different fixed output levels.
