AP7315D-30FS4-7B

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

The AP7315D-30FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 3.0V output voltage and an X2-DFN1010-4 package. It supports an input voltage range of 1.7V to 5.25V with a guaranteed output current of 150mA. The device incorporates an integrated resistor network for high output voltage accuracy (±1%) and includes an enable pin for power control. Key electrical characteristics include a ripple rejection of 75dB at 1kHz, low output noise of 60µVrms from 10Hz to 100kHz, and a quiescent current as low as 35µA. It operates within an ambient temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated auto-discharge circuit that actively pulls the output voltage to ground when the enable pin is deactivated.
• High supply voltage ripple rejection capability designed to minimize noise in sensitive analog circuits.
• Low output noise performance suitable for powering RF modules and precision sensors.
• Built-in short-circuit protection and thermal shutdown mechanisms to safeguard against overcurrent conditions.

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

Verify the specific ordering suffix FS4-7B to confirm the X2-DFN1010-4 package and tape-and-reel packaging quantity. Ensure the D suffix is present to verify the inclusion of the internal discharge feature. Cross-reference the manufacturer part number with official Diodes Incorporated documentation to confirm RoHS compliance and lead-free status before finalizing procurement orders.

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

Select this component when a compact footprint is required alongside precise 3.0V regulation. The D variant is necessary if automatic output discharge upon shutdown is needed. Evaluate the dropout voltage requirements against the minimum input voltage to ensure stable operation under varying load conditions. Confirm that the 150mA current rating meets the peak demands of the target application circuitry.

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

This part belongs to the AP7315 series of CMOS low dropout regulators. The series offers various fixed output voltages ranging from 1.1V to 3.3V. The AP7315D-30FS4-7B specifically utilizes the X2-DFN1010-4 package, which provides a small surface area for dense PCB layouts. The 'D' designation distinguishes it from non-discharge versions within the same family.
