... LCD Display Systems Pagers Remote Data Acquisition GENERAL DESCRIPTION The ADM663/ADM666 are precision voltage regulators featur- ing a maximum quiescent current They can be used to give a fixed +5 V output with no additional external compo- nents or can be adjusted from 1 using two external resistors ...

... This is useful when powering liquid crystal displays over wide temperature ranges. The ADM666 has an additional comparator, C3 which com- pares the voltage on the Low Battery Input, LBI, pin to the in- ternal +1.3 V reference. The output from the comparator drives REV ...

... SET Low Supply or Low Battery Detection The ADM666 contains on-chip circuitry for low power supply or battery detection. If the voltage on the LBI pin falls below the internal 1.3 V reference, then the open drain output LBO will go low. The low threshold voltage may be set to any voltage above 1 ...

... A regulator’s minimum input-output differential or dropout voltage determines the lowest input voltage for a particular out- put voltage. The ADM663/ADM666 dropout voltage is 0 its rated output current. For example when used as a fixed +5 V regulator the minimum input voltage is +5 lower output ...
