Two-terminal current source supplies 200 mA

摘要

Linear Technology Corp's new LT3092 two-terminal current source can supply 0.5 to 200 mA of current at a 1 % initial accuracy. The device operates at 1.5 to 40V and exhibits less-than-1-mV typical load regulation and less-than-0.001％/V typical line regulation. The device needs no bypass capacitance on the input or the output in most ranges of operation, even when you use it at 0.5V. The output is short-circuit-protected and can withstand reverse voltage, and a thermal-shutdown circuit prevents overheating. You can configure the devices in parallel for greater current, or you can stack them in series for greater voltage compliance.
