DESCRIPTION
The TPS715xx 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
(≥ 0.47 µF). The low dropout 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The usual PNP pass transistor has been replaced by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 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).
APPLICATIONS
• Ultra-Low Power Microcontrollers
• Cellular/Cordless Handsets
• Portable/Battery-Powered Equipment
