Overview
The AP7315D-22FS4-7B is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.2V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 1.7V to 5.25V and features a quiescent current as low as 35µA. It incorporates an enable pin for power control and includes an auto-discharge function when disabled. The component is housed in an X2-DFN1010-4 package.
Feature Summary
- Integrated resistor network delivers precise fixed output voltage accuracy
- Built-in discharge mechanism automatically pulls the output low upon shutdown
- CMOS process architecture ensures minimal power consumption during operation
- High ripple rejection capability effectively suppresses input supply noise
Applications
- Smart Phone/PAD
- RF Supply
- Cameras
- Portable Videos
- Wireless Communication
Procurement Notes
Verify that the specific part number matches the required output voltage, package type, and discharge feature before ordering. Confirm compliance with environmental directives such as RoHS and Halogen-free status. Ensure the supplier source is authorized to guarantee product authenticity and traceability. Review the datasheet for absolute maximum ratings to prevent operational damage.
Selection Notes
Select this variant specifically for applications requiring a 2.2V fixed output. The 'D' suffix indicates the inclusion of an internal auto-discharge resistor, which is critical for systems needing rapid output voltage decay. The FS4 designation confirms the X2-DFN1010-4 package, suitable for dense PCB layouts. Verify that the load requirements do not exceed the 150mA continuous current limit.
Part Context
This component belongs to the AP7315 series of low dropout regulators designed for low power handheld communication equipment. The series offers various fixed output voltages ranging from 1.1V to 3.3V. The AP7315D-22FS4-7B represents a specific configuration within this family, combining the 2.2V output option with the X2-DFN1010-4 surface mount package and the discharge feature.

FAQ
What is the function of the 'D' suffix in the part number?
The 'D' suffix indicates that the regulator includes an internal auto-discharge resistor. When the enable pin is pulled low, this resistor actively discharges the output capacitor to rapidly bring the output voltage to zero.
How does the enable pin operate on this device?
The enable pin controls the state of the regulator. Driving the pin high turns the regulator on, while pulling it low activates the shutdown mode and engages the auto-discharge function if present.
