The TPS73801 is a low-dropout (LDO)
regulator optimized for fast transient response. The device can supply 1.0A of
output current with a dropout voltage of 300mV. Operating quiescent current is 1mA,
dropping to less than 1µA in shutdown. Quiescent current is well controlled and does
not rise in dropout, which occurs with many other regulators. In addition to fast
transient response, the TPS73801 regulators have very low output noise, which makes
them designed for sensitive RF supply applications.
Output voltage range is from 1.21V to
20V. The TPS73801 regulators are stable with output capacitors as low as 10µF. 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 1.21V reference voltage. The
TPS73801 regulators are available in the 6-pin TO-223 (DCQ) packages.
