Overview
The AP7315-15FS4-7B is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 1.5V output voltage and housed in an X2-DFN1010-4 package. It supports an input voltage range of 1.7V to 5.25V with a guaranteed maximum output current of 150mA. The device provides high output voltage accuracy of ±1%, ripple rejection of 75dB at 1kHz, and low output noise of 60µVrms from 10Hz to 100kHz. Quiescent current is as low as 35µA, and it operates within an ambient temperature range of -40°C to +85°C.
Feature Summary
- Includes an enable pin for power control and built-in short circuit protection
- Utilizes CMOS process technology for low quiescent current and low on-resistance
- Features integrated resistor network for precise fixed output voltage delivery
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify the specific ordering suffix FS4-7B confirms the X2-DFN1010-4 package and tape & reel packaging quantity. Ensure the part number matches the exact 1.5V output requirement. Confirm RoHS compliance and lead-free status if required by your manufacturing standards. Check for any automotive qualification requirements if intended for AEC-Q100 applications.
Selection Notes
Select this component when a stable 1.5V rail is needed with minimal footprint. The X2-DFN1010-4 package suits dense PCB layouts. Consider the 150mA current limit and 1.7V minimum input voltage for battery-powered designs. Verify that the low noise and high PSRR meet the sensitivity requirements of RF or camera modules.
Part Context
This part belongs to the AP7315 series of low dropout regulators designed for handheld communication equipment. The series offers various fixed output voltages ranging from 1.1V to 3.3V. It is available in multiple packages including SOT23, SOT25, and X2-DFN1010-4 to accommodate different space constraints.

FAQ
What is the function of the EN pin?
The EN pin enables or disables the regulator. Driving it high turns the regulator on, while pulling it low puts it into shutdown mode.
Does this part have an auto-discharge feature?
No, the AP7315-15FS4-7B does not include an auto-discharge feature. For parts with this capability, look for the 'D' suffix in the part number.
