The AP7201 is a dual low-dropout (LDO) CMOS linear regulator. The device operates from 1.9V to 5.5V input and delivers up to 150mA per output channel.
The AP7201 includes a pass element, voltage reference, error amplifier, current limit and built-in phase compensation. Key features include individual logic-compatible enable/shutdown control inputs, fold-back current limit and thermal shutdown protections.
The AP7201 is fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. The fixed output voltage for each channel is set independently. Voltages are 100mV per step within a range of 1.0V to 3.3V.
The EN function allows the output of each channel to be turned off independently, resulting in greatly reduced power consumption. The AP7201 is available in the DFN2018-6 (USP-6B) package.
