Introduction

The DS8571 series are low dropout (LDO) voltage regulators featuring a wide input voltage range (2.3V to 6V), low dropout voltage, low power consumption, and compact packaging. Their fast transient response makes them well-suited for applications requiring rapid load transitions. By selecting the variant with an enable (EN) pin and pulling it low, shutdown mode can be activated, with a typical shutdown current of only 100nA. These linear regulators maintain stability with ceramic output capacitors across the full input voltage range of 2.3V to 6V and output load current range of 0mA to 300mA.
