General Description
The Maxim ICL7663 is a high efficiency positive voltage
regulator with a quiescent current of less than 10p.A. The
output voltage is set by two external resistors to any volt-
age 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 log-
ic 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 ICL76638 is a reduced input voltage range version
limited to a maximum of 10V input.
