Description

General part information

TPS77401 Series

The TPS773xx and TPS774xx are low-dropout regulators with integrated power-on reset and power good (PG) function respectively. These devices are capable of supplying 250 mA of output current with a dropout of 200 mV (TPS77333, TPS77433). Quiescent current is 92 uA at full load dropping down to 1 uA when device is disabled. These devices are optimized to be stable with a wide range of output capacitors including low ESR ceramic (10 uF) or low capacitance (1 uF) tantalum capacitors. These devices have extremely low noise output performance (55 uVrms) without using any added filter capacitors. TPS773xx and TPS774xx are designed to have fast transient response for larger load current changes.

The TPS773xx or TPS774xx is offered in 1.5-V, 1.6 V (TPS77316 only), 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 TPS773xx and TPS774xx 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 200 mV at an output current of 250 mA 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 uA over the full range of output current, 0 mA to 250 mA). These two key specifications yield a significant improvement in operating life for battery-powered systems.
