Product Summary
The TPS73018DBVR is a low-dropout (LDO) low-power linear voltage regulator. It 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 of the TPS73018DBVR in the family is stable, with a small 2.2-μF ceramic capacitor on the output. The SOT23-5 uses an advanced, roprietary BiCMOS fabrication process to yield low dropout voltages. Each device of the TPS73018DBVR achieves fast start-up times 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 TPS73018DBVR exhibits approximately 23 μVRMS of output voltage noise at 2.8-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.
