TPS73047DBVRG4 Description
The TPS73047DBVRG4 low-dropout (LDO) low-power linear voltage regulators feature high power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses in a small SOT-23 package. NanoStarTM packaging gives an ultrasmall footprint as well as an ultralow profile and packages weight, making it ideal for portable applications such as handsets and PDAs. The TPS73047DBVRG4 is stable, with a small, 2.2-μF ceramic capacitor on the output.
