The ICL7663S is a low-power, high-efficiency positive voltage regulator that 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.
The ICL7663S is a CMOS programmable micropower positive voltage regulator designed for battery‑powered supplies. It accepts 1.6 V to 16 V inputs and provides adjustable outputs from 1.3 V to 16 V, with a typical quiescent current of only a few microamps and guaranteed line and load regulation over a wide temperature range.
Key features include 1 % output voltage accuracy (ICL7663SA version), current‑limit sensing, logic‑controlled shutdown, and the ability to generate temperature‑compensated output voltages. The device is offered in PDIP and SOIC packages and is RoHS‑compliant.
