Overview
The AP7313-33SAG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.3V 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 (PSRR) of 65dB at 100Hz. The component supports fast transient response with an 80µs start-up time and is compatible with low ESR ceramic capacitors.
Feature Summary
- Integrates built-in current limit, short circuit protection, and thermal shutdown circuitry to prevent damage during fault conditions.
- Delivers excellent load and line transient response suitable for applications requiring rapid changes in load current.
- Ensures stability with small value low ESR ceramic output capacitors without requiring a minimum load current.
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 matches the required package type and environmental compliance. Confirm the specific output voltage code aligns with system requirements. Check for RoHS3 and REACH status documentation. Ensure the supplier source is authorized to avoid counterfeit components. Review the latest product change notifications for any manufacturing updates.
Selection Notes
Select this regulator when a fixed 3.3V rail is needed with minimal ground current consumption. It is appropriate for designs utilizing standard ceramic capacitors for cost and size reduction. Consider the thermal resistance and ambient temperature limits if operating near the maximum load current. Verify that the input voltage remains within the specified operational range under all conditions.
Part Context
This component belongs to the AP7313 series of low dropout linear regulators from Diodes Incorporated. The series includes various fixed output voltage options ranging from 1.0V to 3.3V. The part is available in SOT23 and SOT23R packages. It is designed for low power applications where battery life and compact footprint are critical design constraints.
Replacement Considerations
Other variants within the AP7313 family offer different fixed output voltages such as 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, and 3.0V. The AP7313-33SRG-7 is the equivalent part in the SOT23R package. Ensure pinout compatibility and electrical specifications match before substitution.
