DESCRIPTION
The TPS715xx low-dropout (LDO) voltage regulators
offer the benefits of high input voltage, LDO voltage,
low-power operation, and miniaturized packaging.
The devices, which operate over an input range of
2.5 V to 24 V, are stable with any capacitor
(>0.47 μF). The LDO voltage and low quiescent
current allow operations at extremely low power
levels. Therefore, the devices are ideal for powering
battery-management ICs. Specifically, since 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The usual PNP pass transistor has been replaced by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 LDO
voltage, typically 415 mV at 50 mA of load current, is
directly proportional to the load current. The low
quiescent current (3.2 μA typ) is stable over the
entire range of output load current (0 mA to 50 mA).
