Overview
The AP7315D-11FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring an integrated resistor network for fixed output voltage. It operates within an input voltage range of 1.7V to 5.25V and guarantees an output current of 150mA. The device provides high output voltage accuracy with a tolerance of ±1% at room temperature. It incorporates an enable pin for power control and includes short-circuit protection. The component utilizes the X2-DFN1010-4 package.
Feature Summary
- Integrated auto-discharge circuitry that actively pulls down the output voltage when disabled
- High ripple rejection capability combined with low output noise for sensitive applications
- Low quiescent current consumption optimized for battery-powered portable devices
- Built-in thermal and current limit protection mechanisms
Applications
- Smartphones and tablet computers
- RF supply circuits
- Portable video players
- Wireless communication adapters
Procurement Notes
Verify the specific ordering suffix FS4-7B confirms the X2-DFN1010-4 package and tape-and-reel packaging quantity. Ensure the D designation matches the required discharge functionality for your design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this part when a fixed 1.1V output is required alongside active output discharge capabilities. The X2-DFN1010-4 package is suitable for dense PCB layouts requiring minimal footprint. Consider the 150mA current guarantee and low dropout characteristics for efficient power management in handheld equipment.
Part Context
This component belongs to the AP7315 series of low dropout regulators from 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 'D' variant specifically denotes the inclusion of an internal discharge resistor for faster shutdown times.
Replacement Considerations
AP7315-11FS4-7B serves as a direct substitute if output discharge functionality is not required in the application.
