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 replacem ent for the industry stan dard ICL7663B
offering wider operating voltage and temper ature ranges,
improved output acc uracy ( ICL7663SA) , better t empera ture
coefficient, guaranteed maximum supply current, and
guaranteed line and load regulation. All improvements are
highlighted in the electrical characteristics section. Critical
parameters ar e guaranteed over the entire commercial
and industrial temperature ranges. The ICL7663S/SA
programmable out put voltage is set by two ext ernal resist ors.
The 1% referen ce a ccuracy of the I CL766 3SA eli minates the
need for trimming the output voltage in most applications.
The ICL7663S is well suit ed for battery powered supplies,
featuring 4µA quiesce nt current , low V
output curren t sensing and logic input level shutdown
control. In addi tion, the ICL7663S has a negative
temperature coefficient output sui table for generating a
temperature compensated display drive voltage for LCD
displays.

NOTES:
3. This parameter refers to the saturation resistance of the MOS pass transistor. The minimum input-output voltage differential at low curre nt (u nder
5mA), can be determined by multiplying the load current (including set resist or curren t, 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 regul ator at V
coefficient results in the output voltage. See Figure 9 for details. Pin will not source current.
