GENERAL DESCRIPTION
The HT-LREG is a hybrid linear regulator designed to operate over an extremely wide temperature range. The regulator's control circuit is fabricated with Honeywell's dielectrically isolated high-temperature (HTMOSTM) process. A silicon-on-insulator MOSFET is the power device. The HT-LREG is designed specifically for severe hightemperature applications such as down-hole oil well, aerospace, turbine engine and industrial control.

Shutdown
The HT-LREG is available with a calibrated +5, +10, or +15V output. Output current is 300 mA over the specified temperature range, while quiescent current is 2.0 mA. Internal short circuit protection is provided which includes current limit and foldback. All parts are burned in at elevated temperature to eliminate infant mortality. Additionally, each part is tested over -55 to +225°C to provide guaranteed performance over the entire temperature band. The HT-LREG is a high-reliability part designed specifically for applications with an extremely wide operating temperature range.
