description
The TPS773xx and TPS774xx are low-dropout
regulators with integrated power-on reset and
power good (PG) function respectively. These
devices are capable of supplying 250 mA of output
current with a dropout of 200 mV (TPS77333,
TPS77433). Quiescent current is 92
碌A
at full load
dropping down to 1
碌A
when device is disabled.
These devices are optimized to be stable with a
wide range of output capacitors including low ESR
ceramic (10
碌F)
or low capacitance (1
碌F)
tantalum capacitors. These devices have ex-
tremely low noise output performance (55
碌V
rms
)
without using any added filter capacitors.
TPS773xx and TPS774xx are designed to have
fast transient response for larger load current
changes.

The TPS773xx or TPS774xx is offered in 1.5-V, 1.6 V (TPS77316 only), 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 TPS773xx and TPS774xx families are
available in 8-pin MSOP (DGK) packages.
