Overview
The AP7313-25SAG-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 features a typical quiescent current of 65µA. It includes built-in current limit, short circuit, and thermal shutdown protections. The component is housed in a SOT-23 package and supports operation across an ambient temperature range of -40°C to 85°C.
Feature Summary
- Provides fast transient response suitable for DSP and GSM chipset applications
- Maintains stability using low ESR ceramic capacitors as small as 1µF
- Includes integrated protection against over-current, short circuits, and overheating
Applications
- Portable devices
- Battery powered devices
- Notebook and desktop computers and peripherals
- CD-ROM, DVD and LAN cards
Procurement Notes
Verify the specific ordering suffix 'SA' corresponds to the SOT-23 package variant rather than the SOT-23R option. Confirm that the '-7' suffix indicates tape and reel packaging. Ensure compliance with RoHS directives and check for any applicable exemptions before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 2.5V rail is required for low-power portable electronics. The low quiescent current makes it efficient for battery-operated systems. Verify that the input voltage remains between 2V and 6V and that the load does not exceed 150mA. Ensure the application environment stays within the specified operating temperature limits.
Part Context
This part belongs to the AP7313 series of 150mA low dropout regulators from Diodes Incorporated. The series offers various fixed output voltages ranging from 1.0V to 3.3V. The AP7313-25SAG-7 specifically denotes the 2.5V output version packaged in SOT-23 with green molding compound and tape-and-reel delivery.
Replacement Considerations
Other variants within the AP7313 family, such as AP7313-XXSRG-7, offer the same electrical characteristics but utilize the SOT-23R package. Direct substitution requires verifying pinout compatibility and physical footprint constraints on the PCB layout.
