AP7340-185FS4-7

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

The AP7340-185FS4-7 is a fixed-output linear low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 1.85V with an accuracy of ±1%. The device supports a maximum output current of 150mA and operates within an input voltage range of 1.7V to 5.25V. Key electrical characteristics include a quiescent current as low as 35µA, a ripple rejection ratio of 75dB at 1kHz, and an output noise voltage of 60µVrms from 10Hz to 100kHz. It features fold-back short circuit protection and is housed in an X2-DFN1010-4 package.

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

Verify the specific suffix FS4-7 corresponds to the required X2-DFN1010-4 package and tape-and-reel quantity. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation. Ensure the ordering part number matches the exact 1.85V output variant to avoid functional mismatches in the design.

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

Select this component when a stable 1.85V rail is required for portable electronics. The low quiescent current makes it suitable for battery-powered devices. Verify that the input voltage remains within the 1.7V to 5.25V range and that the load does not exceed 150mA. Consider the thermal dissipation capabilities of the X2-DFN1010-4 package for the intended PCB layout.

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

This part belongs to the AP7340 series of high PSRR low noise LDOs. The series offers various fixed output voltages ranging from 1.1V to 3.3V. The AP7340D variant includes an auto-discharge feature on the output when disabled, whereas the standard AP7340 does not. Both share similar electrical performance and packaging options.
