These devices are capable of supplying 150 mA of output current with a dropout of 115 mV (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 ceramic (10 µF) or low capacitance (1 µF) 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 1.8-V, 2.7-V, 2.8-V and 3.3-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. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. This document contains information on products in more than one phase of development. The status of each device is indicated on the page(s) specifying its electrical characteristics.
