LT1121 5V Battery-Powered Supply with Shutdown

Apr 20th 1992
The LT1121/LT1121-3.3/LT1121-5 are micropower low dropout regulators with shutdown. These devices are capable of supplying 150mA of output current with a dropout voltage of 0.4V. Designed for use in battery-powered systems, the low quiescent current, 30µA operating and 16µA in shutdown, makes them an ideal choice. ...

LTC1453/LT1077/LT1121 Isolated 4 – 20mA Current Loop

Jan 1st 1987
This circuit is a computer-controlled 4 – 20mA current loop. It is designed to operate on a single supply over a range of 3.3V to 30V. The circuit’s zero output reference signal, 4mA, is set by R1 and calibrated using R2, and its full-scale output current is set by R3 and calibrated using R4. The zero and full-scale ...
