Products Data Sheet  
AnaSem  
Analog Semiconductor IC  
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  
HALOGEN  
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  
RoHS  
ESR capacitor as an output stabilization capacitor. The charged ESR  
capacitor can be discharged with an internal switch by making the EN=VSS  
COMPLIANCE  
,
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.
