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 4?A 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.
