3 Description
The TPS715 low-dropout (LDO) voltage regulators
offer the benefits of high input voltage, low-dropout
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
greater than or equal to 0.47 μF. 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The usual PNP pass transistor has been replaced by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 µA typically) is stable
over the entire range of output load current (0 mA to
50 mA).
