description The TPS771xx and TPS772xx are low-dropout regulators with integrated power-on reset and power good (PG) function respectively. These devices are capable of supplying 150 m A of output IO = 150 m A current with a dropout of 115 m V (TPS77133, TPS77233). Quiescent current is 92 µA at full load dropping down to 1 µA when device is disabled. These devices are optimized to be stable with a wide range of output capacitors including low ESR IO = 10 m A ceramic (10 µF) or low capacitance (1 µF)

IO = 0 A

tantalum capacitors. These devices have ex- tremely low noise output performance (55 µVrms) without using any added filter capacitors. TPS771xx and TPS772xx are designed to have

fast transient response for larger load current

changes.

The TPS771xx or TPS772xx is offered in 1.5 V, 1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0 V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The TPS771xx and TPS772xx families are available in 8-pin MSOP (DGK) packages. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 m V at an output current of 150 m A for 3.3 volt option) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 92 µA over the full range of output current, 0 m A to 150 m A). These two key specifications yield a significant improvement in operating life for battery-powered systems.
