3 Description
The TPS780 family of low-dropout (LDO) regulators
offer the benefits of ultralow power, miniaturized
packaging, and selectable dual-level output voltage
levels with the VSET pin.
The ultralow-power and dynamic voltage scaling
(DVS) capability which provides dual-level output
voltages let designers customize power consumption
for specific applications. Designers can now shift to a
lower voltage level in a battery-powered design when
the microprocessor is in sleep mode, further reducing
overall system power consumption. The two voltage
levels are preset at the factory and are stored using
EPROM and are available on fixed output voltage
devices.
The TPS780 series of LDOs are designed to be
compatible with the TI MSP430 and other similar
products. The enable pin is compatible with standard
CMOS logic. The TPS780 series also come with
thermal shutdown and current limit to protect the
device during fault conditions. All packages have an
operating temperature range of TJ = –40°C to 125°C.
For more cost-sensitive applications requiring a dual-
level voltage option and only on par IQ, consider the
TPS781 series, with an IQ of 1.0 μA and dynamic
voltage scaling.
