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
μ
A at full load
dropping down to 1
μ
A when device is disabled.
These devices are optimized to be stable with a
wide range of output capacitors including low ESR
ceramic (10
μ
F) or low capacitance (1
μ
F)
tantalum capacitors. These devices have ex-
tremely low noise output performance (55
μ
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 1.8-V, 2.7-V, 2.8-V and 3.3-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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
This document contains information on products in more than one phase
of development. The status of each device is indicated on the page(s)
specifying its electrical characteristics.
