Available in 1.8 V, 1.9 V, 2.3 V, 2.5 V, 3 V,

voltage and low quiescent current allow operation at

3.3 V, 3.45 V, 5 V, and

extremely low power levels. Therefore, the devices

Adjustable (1.2 V to 15 V)

are ideal for powering battery management ICs.

Designed to Support MSP430 Families:

Specifically, because the devices are enabled as

soon as the applied voltage reaches the minimum

–

input voltage, the output is quickly available to power

continuously operating battery charging ICs.

–

2.3-V Version Ensured to Meet 2.2-V Minimum

The usual PNP pass transistor has been replaced by

a PMOS pass element. Because the PMOS pass

element behaves as a low-value resistor, the low

current, is directly proportional to the load current.

The low quiescent current (3.2 µA typically) is stable

over the entire range of output load current (0 mA to
