3 Description
The TPS797xx family of low-dropout voltage
regulators (LDOs) offers the benefits of low-dropout
voltage and ultra-low-power operation. The device is
stable with any capacitor greater than 0.47-μF.
Therefore, implementations of this device require very
little board space due to the miniaturized packaging
and potentially small output capacitor. In addition, the
family includes an integrated open drain active-high
power good (PG) output. Intended for use in
microcontroller-based, battery-powered applications,
the TPS797xx family low dropout and ultra-low-power
operation result in a significant increase in system
battery operating life. The small packaging minimizes
consumption of board space.
The device is enabled when the applied voltage
exceeds the minimum input voltage. 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pass transistor has been replaced by a PMOS pass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 dropout voltage is very
low (typically, 105 mV at 10-mA of load current), and
is directly proportional to the load current. The
quiescent current is ultra-low (1.2-μA, typically) and is
stable over the entire range of output load current
(0 mA to 50 mA). When properly configured with a
pullup resistor, the PG output can implement a
power-on reset or low-battery indicator.
