DESCRIPTION
This three terminal negative regulator is supplied in a hermetically sealed metal
package whose outline is similar to the industry standard TO-220 plastic package. 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 -47 volts.
