Figure 1. Dropout Voltage Versus Output Current
Power good (PG) reports low output voltage and can be used to implement a power-on reset or a low-battery
indicator.
The TPS71xx 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 TPS71xx family is available in PDIP
(8 pin), SO (8 pin), and TSSOP (20-pin) packages. The TSSOP has a maximum height of 1,2 mm.

The D and PW packages are available taped and reeled. Add R suffix to device type (e.g., TPS7150QDR). The TPS7101Q is
programmable using an external resistor divider (see application information). The chip form is tested at 25°C.
