AP7315D-23FS4-7B

Overview

The AP7315D-23FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 2.3V 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.

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 and communication modules.
• Built-in short-circuit protection and thermal shutdown mechanisms to safeguard against overcurrent conditions.

Applications

• Smart Phone/PAD
• RF Supply
• Cameras
• Portable Videos
• Wireless Communication

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' designation matches system requirements for the integrated output discharge feature. Cross-reference the manufacturer part number with official Diodes Incorporated documentation to validate RoHS compliance and lead-free status before finalizing procurement orders.

Selection Notes

Select this component when a precise 2.3V rail is required alongside active output discharge functionality. The X2-DFN1010-4 package is optimal for designs prioritizing minimal PCB footprint and dense layout constraints. Evaluate the 150mA current limit against peak load demands to ensure adequate headroom. Consider the 75dB PSRR specification if the application involves noise-sensitive signal paths or RF sections requiring clean power delivery.

Part Context

This device belongs to the AP7315 series of CMOS low dropout regulators produced by Diodes Incorporated. The series offers various fixed output voltages ranging from 1.1V to 3.3V across multiple package options including SOT23, SOT25, and X2-DFN1010-4. The AP7315D variant specifically distinguishes itself through the inclusion of an internal discharge resistor, differentiating it from the standard non-discharge AP7315 models.
