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.
