Overview
The AP7313-25SRG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 2.5V output with a maximum load current of 150mA. The device operates within an input voltage range of 2V to 6V and maintains a typical quiescent current of 65µA across the full load spectrum. It features a typical dropout voltage of 150mV at 150mA and offers a power supply rejection ratio of 65dB at 100Hz. The component supports fast transient response with an 80µs start-up time and remains stable using only a 1µF ceramic output capacitor.
Feature Summary
- Very low quiescent current consumption over the entire load range
- Fast transient response capability for rapidly changing loads
- Stable operation with low ESR ceramic capacitors
- Integrated protection against overcurrent, short circuits, and thermal overload
Applications
- Battery powered devices
- Portable devices
- Notebook and desktop computers and peripherals
- CD-ROM, DVD and LAN cards
Procurement Notes
Verify that the ordering suffix SRG-7 corresponds to the SOT23R package, Green molding compound, and Tape & Reel packaging format as defined in the manufacturer's ordering guide. Confirm compliance with RoHS directives and lead-free finish requirements during procurement. Ensure the specific 2.5V output variant matches the design requirement before finalizing orders.
Selection Notes
Select this component when a fixed 2.5V rail is required from a 2V to 6V source. It is suitable for applications demanding minimal ground current and rapid recovery from standby modes. Verify that the PCB layout accommodates the SOT23R footprint and that the input/output capacitors meet the specified ESR and capacitance values for stability.
Part Context
This part belongs to the AP7313 series of 150mA low dropout regulators. The series includes multiple fixed output voltages ranging from 1.0V to 3.3V. Variants are available in both SOT23 and SOT23R packages. All members share common electrical characteristics including low quiescent current, fast transient response, and integrated protection circuitry.
Replacement Considerations
Other AP7313 variants with different output voltages (e.g., AP7313-33SRG-7) may be considered if the voltage level can be adjusted. Cross-referencing pinouts and package dimensions is essential when substituting with components from other manufacturers.
