TPS73018 - Texas Instruments

TPS73018 200-mA Low-Dropout Linear Regulators

The TPS730 family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses in a small SOT-23 package. NanoStar™ packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable app.
