Analog Semiconductor IC
High speed, Low dropout, ±1% High output accuracy Dual CMOS Voltage Regulator
VRD Series
GENERAL DESCRIPTIONS
The VRD series are dual positive voltage regulators with high speed, low
voltage dropout and high accuracy output achieved by low current
consumption. Because each regulator is completely separated, the crosstalk
between each regulator can be reduced. 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 CE=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.
