DESCRIPTION

The TPS71501 low-dropout (LDO) voltage regulators

offer the benefits of high input voltage, low dropout

voltage, low-power operation, and miniaturized

packaging. The device, which operates over an input

range of 2.5 V to 24 V, is stable with any capacitor

(≥0.47 mF). The low dropout voltage and low

quiescent current allow operation at extremely low

power levels. Therefore, the devices are ideal for

powering battery-management ICs. 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.

The usual PNP pass transistor has been replaced by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

dropout voltage, typically 415 mV at 50 mA of load

current, is directly proportional to the load current. The low quiescent current (3.2 mA typically) is stable

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

50 mA).
