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.
