Texas Instruments TPS73033 | Demoboard TMDSCNCD280049C

Description

The TPS730 family of low-dropout (LDO) regulators has been optimized for use in noise-sensitive, batteryoperated equipment. The device features extremely low dropout voltages, high PSRR, ultra-low output noise, lowquiescent current (170 μA typically), and enable-input to reduce supply currents to less than 1 μA when theregulator is turned off.

Features

200-mA RF Low-Dropout RegulatorWith linear voltage regulators features high power-supply Enable rejection ratio (PSRR), low noise, fast start-up, and

• Available in Fixed Voltages from 1.8 V to 3.3 V excellent line and load transient responses in a smalland Adjustable Voltages (1.22 V to 5.5 V) SOT-23 package. NanoStar™ packaging gives an
• High PSRR (68 dB at 100 Hz) ultrasmall footprint as well as an ultralow profile andpackage weight, making it ideal for portable - Low Noise (33 μVRMS, TPS73018)applications such as handsets and PDAs. Each
