DESCRIPTION

The LT1085 voltage regulators are monolithic inte grated circuits designed for use in applications requiring a well regulated positive output voltage with low input-output differential voltage.

Features include full power usage of up to 3A load current, internal current limiting and thermal shutdown. Safe area protection on the die is also included, providing protection of the series pass Darlington transistor under most conditions.

The hermetically sealed TO–3 packages are utilised for high reliablitiy and low thermal resistance, whilst the SMD1 package is designed for surface mount applications.
