DESCRIPTION
The TPS783 family of low-dropout regulators (LDOs)
offers the benefits of ultra-low power (I_Q = 500nA),
and miniaturized packaging.
This LDO is designed specifically for battery-powered
applications where ultra-low quiescent current is a
critical parameter. The TPS783, with ultra-low I_Q
(500nA), is ideal for microprocessors,
microcontrollers, and other battery-powered
applications.
The absence of pulldown circuitry at the output of the
TPS783 LDO gives an application the flexibility to use
the regulator output capacitor as a temporary backup
power supply for a short period of time without the
presence of the battery when the LDO is disabled
(during battery replacement).
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 TPS783 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 TPS783 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 +105°C.
