DESCRIPTION
The TPS782 family of low-dropout regulators (LDOs)
offers the benefits of ultra-low power (I_Q = 1mA), and
miniaturized packaging (2×2 SON).
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
(1mA), is ideal for microprocessors, memory cards,
and smoke detectors.
The ultra-low power and miniaturized packaging allow
designers to customize power consumption for
specific applications. Consult with your local factory
representative for exact voltage options and ordering
information; minimum order quantities may apply.
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 LDO is stable with any output capacitor
greater than 1.0mF. Therefore, this device requires
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 500nA and dynamic voltage
scaling.
