High speed, Low dropout, ±1% High output accuracy with On/Off circuit CMOS Voltage Regulator

VRH Series

GENERAL DESCRIPTIONS

The VRH series are positive voltage regulators with high 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 switch by making the EN=VSS,

as a result the VOUT quickly returns to the VSS level. To make the current

capacity of the output transistor not exceeded, the over-current protection

circuit is built in.
