The A4402 simplifies power supply design for microcontrollers and DSPs by integrating a 2 MHz buck regulator and an LDO in a single package. This dual-output regulator offers adjustable output voltages, integrated power-on reset, a watchdog timer, and overcurrent/thermal protection for robust performance.
