Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to confirm the exact output voltage and packaging configuration. Ensure that the ordering information matches the required electrical specifications and environmental compliance standards before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.5V rail is required with minimal ground current consumption. The wide input voltage tolerance allows flexibility in power supply design. Verify that the application load does not exceed the 150mA continuous rating and that the PCB layout accommodates the necessary decoupling capacitors for optimal performance.
Part Context
This component belongs to the AP7311 series of low dropout regulators designed for portable applications. The series offers both adjustable and fixed output options within a compact surface-mount package. The specific model provides a fixed voltage setting, simplifying circuit design compared to adjustable variants while maintaining the same core performance characteristics.

FAQ
What is the minimum capacitance required for stable operation?
The device requires a minimum of 1µF ceramic capacitor on both the input and output pins to ensure stability.
How does the enable pin function?
The EN pin turns the regulator on when set to a logic high level and turns it off when pulled low.
