DESCRIPTION
This three terminal positive 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 57 volts using external resistors.

Notes:
1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The • denotes the specifications which apply over the full operating temperature range.
