GaAs FET Bias Supplies The LTCВ®1983-3 and LTC1983-5 are inverting charge
pump DC/DC converters that produce negative regulated
outputs. The parts require only three tiny external capacitors and can provide up to 100mA of output current. The
devices can operate in open loop mode (creating a –VIN
supply) or regulated output mode depending on the input
supply voltage and the output current.
The LTC1983-3/LTC1983-5 have many useful features for …
