The TPS73801 is a low-dropout (LDO) regulator optimized for fast transient response. The device can supply 1.0 A of output current with a dropout voltage of 300 mV. Operating quiescent current is 1 mA, dropping to less than 1 µA in shutdown. Quiescent current is well controlled; it does not rise in dropout as it does with many other regulators. In addition to fast transient response, the TPS73801 regulators have very low output noise, which makes them ideal for sensitive RF supply applications.

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