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 VOU T 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.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
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. 2. JA is measured with the component mounted on an evaluation PC board in free air.

PARA METER Input-Output Saturation Resistance (Note 3) Specifications Below Applicable to Both ICL7663S and ICL7663SA, Unless Otherwise Specified. V+IN = 9V, VOUT = 5V, TA = 25oC, Unless Otherwise Specified. Notes 4, 5. See Test Circuit, Figure 7 (Continued) SYMBOL RSAT TEST CONDITIONS V+IN = 2V, IOUT1 = 1mA V+IN = 9V, IOUT1 = 2mA V+IN = 15V, IOUT1 = 5mA Load Regulation VOUT IOUT Available Output Current (VOUT2) Negative Tempco Output (Note 4) Temperature Coefficient IOUT2 VTC ITC VTC T Minimum Load Current IL(MIN) Includes V SET Divider TA = 25oC 0oC < TA < 70oC -25oC < TA < 85oC NOTES : 3. This parameter refers to the saturation resistance of the MOS pass transistor. The minimum input-output voltage differential at low current (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 SET, 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.
