Overview
The AP7217D-12YG-13 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.2 V output with a maximum continuous current of 600 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and features a typical dropout voltage of 250 mV at full load. It incorporates internal protection mechanisms including thermal shutdown and current limiting. The component is housed in a SOT-89-3 surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.
Feature Summary
- CMOS architecture designed for low quiescent current consumption
- Integrated thermal shutdown and current limit protection circuits
- Fixed 1.2 V output voltage option for precise rail generation
Applications
- Portable battery-powered equipment requiring efficient voltage regulation
- Embedded systems needing stable 1.2 V logic supply rails
- General-purpose power management in compact consumer electronics
Procurement Notes
Verify the specific suffix 'YG' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions, as variations exist within the AP7217 family. Confirm availability status directly with authorized distributors, as lifecycle notifications may indicate end-of-life or obsolescence phases for this specific part number.
Selection Notes
Select this component when a fixed 1.2 V output is required with moderate current demands up to 600 mA. Ensure the input voltage remains within the 2.5 V to 5.5 V operational window. Consider the SOT-89-3 package constraints for thermal dissipation if operating near maximum current limits in enclosed environments.
Part Context
This part belongs to the AP7217 series of CMOS LDO regulators from Diodes Incorporated. The series offers various fixed output voltages and packages, including SOIC-8 and SOT-89-3. The AP7217D variant specifically denotes the 1.2 V output version in the SOT-89-3 package, distinguishing it from other voltage options like 1.25 V or 3.3 V within the same product line.
Replacement Considerations
Direct substitutes include other AP7217 variants with identical pinouts but different output voltages if voltage adjustment is possible, or generic 600mA 1.2V LDOs in SOT-89-3 packages such as the AP7217C-12YG-13 if available. Verify electrical parameters and thermal characteristics before substitution.
