Linear Technology LTC1983-3/LTC1983-5 Datasheet
Datasheet 12 pages · 177 KB · EN
The LTC1983-3 and LTC1983-5 are inverting charge pump DC/DC converters that produce negative regulated outputs of -3V or -5V, respectively. These devices require only three tiny external capacitors and can provide up to 100mA of output current. They are designed for portable equipment, LCD bias supplies, and GaAs FET bias supplies, operating from a single supply voltage.
