The TPS73801-SEP is a low-dropout (LDO) regulator optimized for fast transient response. The device can supply 1 A of output current with a dropout voltage of 300 mV. Operating quiescent current is 1 mA and drops to less than 1 µA in shutdown. Compared to many other regulators, quiescent current is well controlled and does not rise in dropout. In addition to fast transient response, a very low output noise makes the TPS73801-SEP regulator ideal for sensitive RF supply applications.

Output voltage range is from 1.21 to 20 V and is stable with use of output capacitors as low as 10 µF. Small ceramic capacitors can be used without the necessary addition of ESR. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse-current protection. The TPS73801-SEP regulator is available with an adjustable 1.21-V reference voltage and in the 6-pin TO-223 (DCQ) package.
