ADP2121ACBZ-1.8-R7

The ADP2121 has an input voltage range of 2.3 V to 5.5 V and can use a single Li+/Li-polymer battery, multiple alkaline/NiMH batteries, PCMCIA, and other standard power supplies. ADP2121 requires only three external devices with fixed output voltages of 1.80 V, 1.82 V, 1.85 V, and 1.875 V and a source current of up to 500 mA. Other key features of this device include: undervoltage lockout (UVLO) to prevent deep battery discharge; Soft start to prevent input current overshoot during start-up. During logic control shutdown, the input is disconnected from the output and the source current is less than 0.28 μA.
