Overview
The AP7311-33SNG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.3V output with a maximum current capacity of 150mA. The device operates within an input voltage range of 2V to 6V and maintains a typical dropout voltage of 250mV at full load. It features a quiescent current of 85µA and offers high power supply rejection ratio performance. The component is housed in a compact SOT-25 surface-mount package, suitable for space-constrained portable electronics applications.
Feature Summary
- Fixed 3.3V output voltage for precision regulation
- Compact five-pin SOT-25 surface-mount package
- Low quiescent current consumption for battery efficiency
- Integrated thermal shutdown protection
Applications
- Portable consumer electronics
- Battery-powered devices
- Embedded systems requiring stable 3.3V logic levels
Procurement Notes
Verify the specific suffix 'WG' or 'SNG' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required output current and voltage specifications for the target circuit design before procurement.
Selection Notes
Select this component when a fixed 3.3V rail is required with moderate current demands up to 150mA. Consider the SOT-25 package size constraints and the 2V to 6V input voltage window. Verify that the thermal dissipation requirements are met within the operating temperature range of -40°C to +85°C.
Part Context
This part belongs to the AP7311 series of low dropout regulators from Diodes Incorporated. The series includes various output voltage options and package configurations. The AP7311-33SNG-7 specifically denotes the 3.3V fixed output version in the SOT-25 package, designed for general-purpose linear regulation tasks.
Replacement Considerations
Direct substitutes include other AP7311 variants with different output voltages if voltage adjustment is possible, or equivalent 150mA LDOs in SOT-25 packages from other manufacturers. Verify pinout compatibility and electrical parameters such as dropout voltage and quiescent current.
