CMOS Programmable Micropower
Positive Voltage Regulator
The ICL7663S Super Programmable Micropower Voltage
Regulator is a low power, high efficiency positive voltage
regulator which accepts 1.6V to 16V inputs and provides
adjustable outputs from 1.3V to 16V at currents up to 40mA.
It is a direct replacement for the industry standard ICL7663B
offering wider operating voltage and temperature ranges,
improved output accuracy (ICL7663SA), better temperature
coefficient, guaranteed maximum supply current, and
guaranteed line and load regulation. All improvements are
highlighted in the electrical characteristics section. Critical
parameters are guaranteed over the entire commercial
and industrial temperature ranges. The ICL7663S/SA
programmable output voltage is set by two external resistors.
The 1% reference accuracy of the ICL7663SA eliminates the
need for trimming the output voltage in most applications.
The ICL7663S is well suited for battery powered supplies,
featuring 4µA quiescent current, low VIN to VOUT differential,
output current sensing and logic input level shutdown
control. In addition, the ICL7663S has a negative
temperature coefficient output suitable for generating a
temperature compensated display drive voltage for LCD
displays.
