Product Description

General Description

The CYP7901 series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and laser trimming technologies. The CYP7901consists of a high-precision voltage reference, an error amplification circuit, and a current limited output driver. Transient response to load variations have improved in comparison to the existing series.

Notes:

1. VOUT(S): Output voltage when VIN= Vout +2V, Iout=1 mA.
2. VDROP=Vin1 -(Vout(S)× 0.98)where Vin1 is the input voltage when Vout = Vout (S)× 0.98. 3.ILIM : Output current when Vin=Vout (S)+1V and Vout = 0.98*Vout (S).
