The TPS771xx and TPS772xx are low-dropout
250
regulators with integrated power-on reset and
power good (PG) function respectively. These
200
devices are capable of supplying 150 mA of output
current with a dropout of 115 mV (TPS77133,
TPS77233). Quiescent current is 92 µA at full load
150
IO = 150 mA
dropping down to 1 µA when device is disabled.
These devices are optimized to be stable with a
100
wide range of output capacitors including low ESR
ceramic (10 µF) or low capacitance (1 µF)
50
tantalum capacitors. These devices have ex-

IO = 0 A
tremely low noise output performance (55 µV_rms)

without using any added filter capacitors.
TPS771xx and TPS772xx are designed to have
fast transient response for larger load current
changes.
The TPS771xx or TPS772xx is offered in 1.5 V,

1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0 V fixed-voltage versions and in an adjustable version (programmable over
the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The
TPS771xx and TPS772xx families are available in 8-pin MSOP (DGK) packages.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 mV
at an output current of 150 mA for 3.3 volt option) and is directly proportional to the output current. Additionally,
since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent
of output loading (typically 92 µA over the full range of output current, 0 mA to 150 mA). These two key
specifications yield a significant improvement in operating life for battery-powered systems.
