Overview
The AP7201-1011FMG-7 is a dual low-dropout (LDO) CMOS linear regulator manufactured by Diodes Incorporated. It operates from an input voltage range of 1.9V to 5.5V and delivers up to 150mA per output channel. The device features fixed output voltages of 1.0V on Output 1 and 1.1V on Output 2, with a typical quiescent current of 25uA. It includes individual logic-compatible enable/shutdown control inputs, fold-back current limit, and thermal shutdown protections.
Feature Summary
- Dual independent channels with individual active-high enable/shutdown control inputs for power reduction
- Compatible with low ESR ceramic capacitors to reduce cost and improve stability
- Includes built-in phase compensation, fold-back current limiting, and thermal shutdown protection
Applications

Procurement Notes
Verify the specific output voltage configuration matches the design requirements, as the suffix '1011' indicates 1.0V for Output 1 and 1.1V for Output 2. Confirm the package type is DFN2018-6 (USP-6B). Ensure the application environment stays within the specified operating temperature range of -40°C to +85°C. Check datasheet notes regarding custom laser trimming availability if non-standard voltage combinations are needed.
Selection Notes
Select this component when a dual-channel LDO solution is required for portable electronics. It is suitable for applications needing independent channel control via logic-compatible enable pins. Consider its low quiescent current for battery-powered devices. Verify that the load current does not exceed 150mA per channel and that the input voltage remains within the 1.9V to 5.5V range.
Part Context
The AP7201 series consists of dual low-dropout linear regulators designed for portable applications. This specific part number represents a variant with fixed 1.0V and 1.1V outputs. It belongs to the AP7201 family, which offers various fixed voltage combinations ranging from 1.0V to 3.3V. The device is housed in a compact DFN2018-6 package.

FAQ
What is the function of the EN pins?
The EN1 and EN2 pins are active-high enable inputs that allow each output channel to be turned on or off independently, reducing power consumption.
How does the AP7201 handle short circuits?
It employs a fold-back current limit mechanism that clamps the output current to approximately 300mA during excessive load conditions and reduces it to about 40mA during a short circuit to GND.
