The document introduces the features of the ICL7663S/SA super programmable micro power positive voltage regulator product, including input and output voltage range, working temperature range, maximum static current, line regulation, load regulation and other characteristics
The ICL7663S is a low‑power, high‑efficiency positive voltage regulator that accepts 1.6 V to 16 V inputs and provides adjustable outputs from 1.3 V to 16 V. It features a 4 µA quiescent current, programmable output voltage set by two external resistors, and optional negative temperature‑coefficient output.
Designed for battery‑powered and portable instrumentation, the device includes logic‑controlled shutdown, current‑limit sensing, and can be boosted with an external transistor for currents above 40 mA. Typical applications include pagers, handheld instruments, LCD display drivers, and remote data‑loggers.
