3 Description
The TPS782 family of low-dropout regulators (LDOs)
offers the benefits of ultra-low power and miniaturized
packaging.
This LDO is designed specifically for battery-powered
applications where ultra-low quiescent current is a
critical parameter. The TPS782, with ultra-low I_Q (500
nA), is ideal for microprocessors, microcontrollers,
and other battery-powered applications.
The ultra-low power and miniaturized packaging allow
designers to customize power consumption for
specific applications.
The TPS782 family is designed to be compatible with
the TI MSP430 and other similar products. The
enable pin (EN) is compatible with standard CMOS
logic. This device allows for minimal board space
because of miniaturized packaging and a potentially
small output capacitor. The TPS782 series also
features thermal shutdown and current limit to protect
the device during fault conditions. All packages have
an operating temperature range of T_J = –40°C to
125°C.
For high-performance applications that require a dual-
level voltage option, consider the TPS780 series, with
an I_Q of 500 nA and dynamic voltage scaling.
