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

parameters are guaranteed over the entire commercial and industrial temperature ranges.
programmableoutputvoltageis set bytwo 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 V 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.

NOTES:
1. Connecting any terminal to voltages greater than (V+IN + 0.3V) or less than (GND - 0.3V) may cause destructive device latch-up. It is recom­mended that no inputs from sources operating on external power supplies be applied prior to ICL7663S power-up.

NOTES:
3. Thisparameter referstothe saturation resistance of the MOS passtransistor.The minimum input-output voltage differential at lowcurrent(under 5mA), can be determined by multiplying the load current (including set resistor current, but not quiescent current) by this resistance.
4. This output has a positive temperature coefficient. Using it in combination with the inverting input of the regulator at V
, a negative

coefficient results in the output voltage. See Figure 9 for details. Pin will not source current.
5. All pins are designed to withstand electrostatic discharge (ESD) levels in excess of 2000V.
6. All significant improvements over the industry standard ICL7663 are highlighted.
