VRHSeries
GENERAL DESCRIPTIONS
The VRH series are positive voltage regulators withhigh speed, low voltage dropout and high accuracy output achieved by low current consumption. The output voltage is guaranteed within ±1% within the given temperature range by Vref controlling the temperature characteristic. It corresponds to the low ESR capacitor as an output stabilization capacitor. The charged ESR
capacitor can be discharged with an internal switchby making the EN=VSS, as a result the VOUTquickly returns to the VSSlevel. To make the current capacity of the output transistor n ot exceeded, the over-current protection circuit is built in.
