TPS73033DBVR Datasheet

Low Dropout Regulators - LDO


The TPS73033DBVR family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow-noise,fast start-up, and excellent line and load transient responses a small SOT23 package. Each device in capacitor on the output. The TPS730xx family uses an advanced, proprietary BiCMOS fabrication process to yield low dropout voltages (e.g., 120 mV at 200 mA, TPS73030). Each device achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor) while consuming low quiescent current (170 μA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 μA. The TPS73018 exhibits approximately 23 μVRMS of output voltage noise at2.8-V output with a 0.01-μF bypass capacitor. Appli- cations 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.
