Power good (PG) reports low output voltage and can be used to implement a power-on reset or a low-battery
indicator.
The TPS71Hxx is offered in 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable version
(programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2%
over line, load, and temperature ranges (3% for adjustable version). The TPS71Hxx family is available in a
TSSOP (20-pin) thermally enhanced surface-mount power package. The package has an innovative thermal
pad that, when soldered to the printed-wiring board (PWB), enables the device to dissipate several watts of
power (see Thermal Information section). Maximum height of the package is 1.2 mm.

The PWP package is only available left-end taped and reeled, as indicated
by the LE suffix on the device type. The TPS71H01Q is programmable using
an external resistor divider (see application information).
