AP7340D-25FS4-7

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

The AP7340D-25FS4-7R is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.5V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features high power supply rejection ratio performance of 75dB at 1kHz. Quiescent current is specified as low as 35µA, while standby current drops to 0.01µA when disabled. Output voltage accuracy is maintained within ±1% at +25°C and ±1.5% across the full operating temperature range of -40°C to +85°C. The component utilizes an X2-DFN1010-4 package.

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

Verify the specific suffix '7R' indicates tape and reel packaging configuration. Confirm the 'D' designation corresponds to the version with integrated output discharge functionality. Ensure the ordering part number matches the required fixed voltage grade and package type from the manufacturer's official ordering information table.

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

Select this variant when a fixed 2.5V rail is required with strict space constraints due to the small package size. Consider the built-in discharge feature if rapid power-down of the load is necessary. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions.

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

This component belongs to the AP7340 series of low dropout regulators designed for handheld communication equipment. The 'D' suffix distinguishes it from the standard AP7340 by including an internal N-channel MOSFET for discharging the output capacitor when the enable signal is low. This series targets applications requiring low noise and high PSRR in portable devices.
