The TPS779xx is a low-dropout regulator with
150
integrated power-on reset. The device is capable
of supplying 250 mA of output current with a
100
dropout of 200 mV (TPS77930). Quiescent
current is 92 µA at full load dropping down to 1 µA
50
IO= 0.05 A
when the device is disabled. The device is optimized to be stable with a wide range of output
0 –50 –30 –10 10 30 50 70 90 110 130
capacitors including low ESR ceramic (10 µF) or low capacitance (1 µF) tantalum capacitors. The
TJ – Junction Temperature – °C
device has extremely low noise output perfor.
