The STMicroelectronics BUCK voltage regulator with a precise voltage reference for MCU applications. All the regulators have internal power switches. The LPM allows the operation under light-load conditions reducing the quiescent current down to 50 μA typ. An internal programmable memory allows selecting the main device parameters like output voltages and switching frequencies. An SPI Interface can be used for diagnostics, programming, monitor and external window watchdog.
