COM137T
(COTS) COMMERCIAL OFF-THE-SHELF 1.5 AMP NEGATIVE, ADJUSTABLE VOLTAGE REGULATOR IN TO-257 PKG
Three Terminal, Precision Adjustable
Negative Voltage Regulator In TO-257 Package
FEATURES
•Built In Thermal Overload Protection
•Short Circuit Current Limiting
DESCRIPTION
These three terminal negative regulators are supplied in hermetically sealed packages. All protective features are designed into the circuit, including thermal shutdown, current-limiting, and safe-area control. With heat sinking, these devices can deliver up to 1.5 amps of output current. The unit also features output voltages that can be fixed from -1.2 volts to -37 volts using external resistors.
