Overview
The AP7313-18SRG-7 is a fixed-output linear regulator providing 1.8V at up to 150mA in an SOT23R package. It operates with input voltages from 2V to 6V and features a typical quiescent current of 65µA. The device offers a dropout voltage of 150mV at full load, 65dB PSRR at 100Hz, and fast transient response. Built-in protections include current limiting, short-circuit protection, and thermal shutdown.
Feature Summary
- Provides stable regulated output with low dropout characteristics for efficient power management
- Features ultra-fast start-up time and excellent load/line transient response capabilities
- Includes integrated over-current, short-circuit, and thermal shutdown protection mechanisms
Applications
- Battery powered devices
- Portable Devices
- Notebook and Desktop Computers and Peripherals
Procurement Notes
Verify the specific ordering suffix SRG-7 confirms the SOT23R package, Green molding compound, and Tape & Reel packaging format. Ensure compatibility with RoHS3 compliance standards and confirm the manufacturer's standard lead times align with project schedules before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1.8V rail is required within a 2V to 6V input range. It is suitable for applications demanding low ground current consumption and fast dynamic response to load changes. Verify that the PCB layout allows for the recommended 1µF ceramic output capacitor placement near the OUT and GND pins.
Part Context
This part belongs to the AP7313 series of 150mA low dropout linear regulators manufactured by Diodes Incorporated. The series provides various fixed output voltage options ranging from 1.0V to 3.3V. The AP7313-18SRG-7 specifically utilizes the SOT23R footprint variant for surface-mount assembly.
Replacement Considerations
AP7313-18SAG-7 (identical electrical specifications in SOT23 package)
FAQ
What is the minimum capacitance required for stable operation?
A 1µF ceramic capacitor is recommended on both the input and output pins to ensure stability and proper transient response.
How does the device handle short circuit conditions?
Short circuit protection triggers when the output voltage drops below 200mV, clamping the output current to approximately 50mA to prevent damage.
