Programmable Postive Voltage Regulator

The Maxim ICL7663 is a high efficiency positive voltage regulator with a quiescent current of less than 10μA. The output voltage is set by two external resistors to any voltage in the 1.3-16V range, with an input voltage range of 1.5-16V. The ICL7663 is well suited for battery powered supplies, featuring low quiescent current, 40mA output current capability, low VIN to VOUT differential, and a logic input level shutdown control. In addition, the ICL7663 has a negative temperature coefficient output suitable for generating a temperature compensated display drive voltage for multiplexed LCD display systems.

The Maxim ICL7663A is an enhanced version of the ICL7663, with a 1% accurate voltage reference, which eliminates the need for trimming the output voltage in most applications.

The ICL7663B is a reduced input voltage range version limited to a maximum of 1 OV input.
