Ultra-High PSRR LDO Regulators

onsemi Ultra-High PSRR LDO Regulators include the NCV816X and NCP16x families of linear regulators. The regulators are capable of supplying a 250mA to 700mA current output current. The NCV816x and NCP16x meet RF and analog circuit requirements. They provide low noise, high PSRR, low quiescent current, and very good load/line transients. onsemi Ultra-High PSRR LDO Regulators work with a 1µF input and a 1µF output ceramic capacitor.
