3 Description
The TPS783 family of low-dropout regulators (LDOs)
offers the benefits of ultralow power and miniaturized
packaging.
This LDO family is designed specifically for battery-
powered applications where ultralow quiescent
current is a critical parameter. The TPS783, with
ultralow IQ (500 nA), is ideal for microprocessors,
microcontrollers, and other battery-powered
applications.
The absence of pulldown circuitry at the output of the
LDO provides the flexibility to use the regulator output
capacitor as a temporary backup power supply (for
example, during battery replacement).
The ultralow 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 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 TPS783 family also features thermal
shutdown and current limit to protect the device
during fault conditions. All packages have a specified
operating temperature range of TJ = –40°C to 105°C.
