MULTI-POWER SUPPLY
RV5VE0
×××
SERIES
OUTLINE
The RV5VE0
×××
series are multi-power supply ICs with high accuracy output voltage and detector threshold
and with ultra low supply current by CMOS process. Each of these ICs consists of four voltage regulators,two volt-
age detectors and control switches.These ICs can achieve the construction of an ideal power supply system in
accordance with the user's mask option.
Output Voltage and Detector Threshold can be independently set within each IC by laser trim. The package
are of 16pin SSOP(0.8mm pitch) and 16pin SSOP(0.65mm pitch).
