Overview
The TPS73033DBVR is a low-dropout (LDO) linear voltage regulator from Texas Instruments, designed for use in noise-sensitive and battery-operated equipment. This regulator is part of the TPS730 family, which features high power-supply rejection ratio (PSRR), low noise, fast start-up times, and excellent line and load transient responses. The device is packaged in a small SOT-23 (DBV) package, making it ideal for portable applications such as handsets, PDAs, and other compact electronic devices.
