S-19222 Series

Provides stable power supplies thanks to the industry’s highest* PSRR and the industry’s fastest* transient response!

The industry’s highest* PSRR helps deliver a stabilized power not impacted by input noise

The 75dB PSRR (at f=1.0kHz) of our S-19222 Series is about 45dB improvement over our conventional product. Since The S-19222 Series can be used with CIN 0.1 μF and COUT 1.0μF input / output capacitors, it helps make customer products more compact and lower cost.

PSRR: Power Supply Rejection Ratio

The industry’s fastest* transient response ensures a stabilized power not impacted by cranking

In the S-19222 Series undershoot and overshoot events, caused by fluctuations in power supply voltage, have been reduced to about 1/60th of those in our conventional product.
It effectively reduces fluctuations in output voltage during cranking without the use of large input / output capacitors.

The current consumption of the S-19222 Series is as low as 22.0µA typ. during operation. Despite high PSRR and fast transient response, it has helped lower the standby current of the overall system.
