Overview
The AP7313-12SRG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.2V output with a maximum continuous 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. 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 start-up times of approximately 80µs and functions reliably in ambient temperatures ranging from -40°C to +85°C.
Feature Summary
- Integrated thermal shutdown and current limit protection mechanisms prevent damage during fault conditions.
- Fast transient response capability ensures stable voltage supply for rapidly changing loads without significant overshoot or undershoot.
- Stable operation is maintained with small ceramic output capacitors, facilitating compact printed circuit board layouts.
Applications
- Battery powered devices
- Portable electronic equipment
- Notebook and desktop computer peripherals
Procurement Notes
Verify the specific ordering suffix SRG-7 confirms the SOT23R package, Green molding compound, and Tape & Reel packaging format. Ensure the part number matches the required 1.2V fixed output variant. Confirm RoHS compliance status and check for any recent design changes or pinout variations documented in official revision notices before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1.2V rail is required with minimal ground current consumption. The wide input voltage range accommodates single-cell battery applications. Verify that the PCB layout allows for adequate copper area to manage thermal dissipation, as the SOT23R package has limited heat spreading capabilities compared to larger packages under high load conditions.
Part Context
This component belongs to the AP7313 series of low dropout regulators designed for portable electronics. The series offers various fixed output voltages and utilizes CMOS technology to achieve low power consumption. The AP7313-12SRG-7 specifically denotes the 1.2V output version housed in the SOT23R surface-mount package with green molding compound.
Replacement Considerations
AP7313-12SAG-7 (identical electrical specifications in standard SOT23 package)
FAQ
What is the minimum recommended output capacitance for stability?
The device is stable with a minimum output capacitance of 1µF ceramic capacitor with low ESR characteristics.
How does the device protect against short circuits?
Short circuit protection clamps the output current to approximately 50mA when the output voltage drops below 200mV.
