AP7333-20SRG-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7333-20SRG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 2.0V output with a maximum load current of 300mA. It operates within an input voltage range of 2V to 6V and features a typical quiescent current of 65µA across the full load spectrum. The device incorporates comprehensive protection mechanisms including current limit, short circuit, and thermal shutdown. Designed for surface-mount assembly, it utilizes the SOT23R-3 package and maintains stability using low ESR ceramic capacitors.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the specific ordering suffix matches the required package type and output voltage configuration. Confirm compliance with environmental directives such as RoHS standards before finalizing procurement. Ensure the supplier provides official datasheets to validate electrical characteristics against application requirements.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.0V rail is required with moderate current demands up to 300mA. Evaluate the input voltage headroom to ensure operation remains within the specified dropout limits under maximum load conditions. Consider the thermal resistance characteristics of the SOT23R package for adequate heat dissipation in enclosed designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AP7333 family of low dropout regulators designed for portable electronics. The series offers various fixed output voltages ranging from 1.0V to 3.3V. The SRG suffix indicates the SOT23R package variant with Green molding compound, distinguishing it from the standard SA package while maintaining identical electrical performance profiles.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Cross-reference with other AP7333 variants sharing the same SOT23R package if different output voltages are needed. Verify pinout compatibility with existing PCB layouts before substituting with alternative LDO families.
