ICL7663S
FN3180.5
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 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.

*Add “-T” suffix to part number for tape and reel packaging.
**Pb-free PDIPs can be used for through hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
