Three Terminal, Precision Adjustable
Negative Voltage Regulator In TO-257 Package
(COTS) COMMERCIAL OFF-THE-SHELF 1.5 AMP NEGATIVE,
ADJUSTABLE VOLTAGE REGULAT OR IN T O-257 PKG
FEATURES
Built In Thermal Overload Protection
Short Circuit Current Limiting
DESCRIPTION
These three terminal negative regulators are supplied in hermetically sealed pack-
ages. All protective features are designed into the circuit, including thermal shutdown,
current-limiting, and safe-area control. W ith 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.
