open-in-new Find other Linear regulators (LDO)

Description

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, 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-SEP regulator has very low output noise, which makes it ideal for sensitive RF supply applications.

Output voltage range is from 1.21 to 20 V. The TPS73801-SEP regulator is 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 device is available as an adjustable device with a 1.21-V reference voltage. The TPS73801-SEP regulator is available in the 6-pin TO-223 (DCQ) package.
