Overview
The AP7313-10SRG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.0V output with a maximum continuous 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 (PSRR) of 65dB at 100Hz. The component is housed in a SOT23R surface-mount package and supports an ambient operating temperature range from -40°C to +85°C.
Feature Summary
- Integrated protection mechanisms including current limit, short circuit, and thermal shutdown safeguard the IC against fault conditions.
- Fast transient response capability ensures stable voltage supply during rapid load transitions without significant overshoot or undershoot.
- Ultra-fast start-up time allows the device to provide full power rapidly after activation, supporting efficient standby mode operations.
Applications
- Portable devices requiring low power consumption
- Battery powered equipment
- Notebook and desktop computer peripherals
Procurement Notes
Verify that the specific part number suffix matches the required pinout configuration for your PCB layout. Confirm compliance with RoHS directives and check for any specific environmental certifications required by your manufacturing standards. Ensure the ordering quantity aligns with standard tape and reel packaging specifications provided by the manufacturer.
Selection Notes
Select this component when a fixed 1.0V rail is needed with minimal ground current draw. Verify that the input voltage remains within the 2V to 6V operational window. Ensure the application load does not exceed 150mA continuously. Check that the output capacitor meets the recommended ESR and capacitance values for stability.
Part Context
This regulator belongs to the AP7313 series, designed for portable electronics. The series emphasizes low quiescent current and fast transient response to extend battery life. It integrates essential protection circuits within a compact three-pin package, making it suitable for space-constrained designs in consumer electronics and computing peripherals.
Replacement Considerations
Compatible substitutes include AP7313-10SAG-7, which utilizes the standard SOT23 package instead of SOT23R. Other variants within the AP7313 family may be considered if different output voltages are acceptable, provided the electrical characteristics meet the design requirements.
FAQ
What is the minimum load requirement for the AP7313-10SRG-7?
No minimum load is required to keep the device stable. The regulator remains stable and regulated even under no-load conditions.
How does the device handle short circuit conditions?
When the output is shorted to ground or the output voltage drops below 200mV, short circuit protection triggers and clamps the output current to approximately 50mA to prevent damage.
