Product Summary

The TPS73033DBVR low-dropout (LDO) low-power linear voltage regulator features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses a small SOT23 package. TPS73033DBVR is stable, with a small 2.2-μF ceramic capacitor on the output. The TPS73033DBVR uses an advanced, proprietary BiCMOS fabrication process to yield low dropout voltages (e.g., 120 mV at 200 mA). TPS73033DBVR achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor) while consuming low quiescent current (170 μA typical). Applications with analog components that are noise-sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise features as well as the fast response time.
