AP7343DQ-30FDUW-7

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

The AP7343DQ-30FDUW-7 is a fixed-output low dropout (LDO) voltage regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 3 V with a maximum output current of 300 mA. The device features a typical power supply rejection ratio (PSRR) of 75 dB and a quiescent current of 35 uA. It operates within an input voltage range of 1.7 V to 5.25 V and maintains a typical dropout voltage of 220 mV. The component is housed in a W-DFN2020-6 package and is qualified under the AEC-Q100 standard for automotive applications, supporting an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix FDUW corresponds to the W-DFN2020-6 (SWP) (Type UXD) package configuration as documented. Confirm AEC-Q100 automotive qualification status through official manufacturer datasheets or authorized distributor specifications before integration into safety-critical designs.

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

Select this component when automotive reliability and low static current are primary requirements. Ensure the input voltage remains within the 1.7 V to 5.25 V range to maintain regulation. Verify thermal dissipation capabilities given the 300 mA output capability and package thermal resistance characteristics.

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

This part belongs to the AP7343 series of low dropout regulators from Diodes Incorporated. The 'DQ' designation typically indicates automotive grade qualification, while '30' specifies the 3 V output voltage. The 'FDUW' suffix defines the specific tape and reel packaging and physical footprint variant.

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

AP7343DQ-30W5-7 offers similar electrical performance but utilizes a SOT-25-5 package instead of W-DFN2020-6. Verify pinout compatibility and thermal management requirements when substituting between these package types.
