Overview
The AP1086TG-U is a low dropout positive adjustable or fixed-mode regulator manufactured by Diodes Incorporated. It provides an output current capability of 1.5A with a maximum dropout voltage of 1.4V at full load. The device operates within an input voltage range of 3V to 12V and supports fixed output voltages including 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V. It utilizes a TO-220-3L package and functions within a junction temperature range of 0°C to 125°C.
Feature Summary
- Provides stable regulation for low voltage IC applications such as high-speed bus termination and logic supplies
- Incorporates built-in thermal shutdown and output current limiting for enhanced protection
- Features fast transient response and good noise rejection characteristics
Applications
- High-speed bus termination circuits
- Low current 3.3V logic supply generation
- VGA card power regulation
Procurement Notes
Verify the specific suffix configuration against official documentation to confirm package type and output voltage settings. Confirm RoHS compliance status and lead-free finish requirements prior to integration. Ensure that the selected heat sink maintains junction temperatures below the maximum allowable limit during continuous operation.
Selection Notes
Select this component when a 1.5A output current is required with minimal input-to-output voltage differential. Consider the TO-220-3L package for through-hole mounting applications requiring robust thermal dissipation. Verify that the application load does not exceed the specified current limits to ensure reliable performance.
Part Context
This part belongs to the AP1086 series of low dropout regulators designed for efficient power management in portable and desktop electronics. The series offers both adjustable and fixed-mode configurations to accommodate various system voltage requirements while maintaining high efficiency under heavy load conditions.
Replacement Considerations
Direct substitutes include other 1.5A LDO regulators from Diodes Incorporated or equivalent manufacturers offering similar pinouts and electrical specifications. Verify thermal resistance values and package dimensions to ensure mechanical compatibility without redesigning the PCB layout.
