Product Summary

The LAS1905 is a voltage regulator. The LAS1905 is monolithic integrated circuits designed for use in applications requiring a well regulated positive output voltage. Outstanding features include full power usage up to 5.0 amperes of load current, internal current limiting, thermal shutdown, and safe area protection on the chip, providing protection of the series pass Darlington, under most operating conditions. Hermetically sealed copper and copper/steel TO-3 packages are ytilized for high reliability and low thermal resistance, while the TO-247 package is intended for cost effective designes. A low-noise, temperature stable band gap reference is the key design factor insuring excellent temperature regulation of the LAS 1900 Series. This, coupled to a very low output impedance, insures superior load regulation.
