Product Overview
The MC7918CTG is a -18V fixed output negative Linear Regulator. The device features current limiting, thermal shutdown and safe-area compensation making them remarkably rugged under most operating conditions. With adequate heatsinking the device can deliver output currents in excess of 1A.
- No external components required
- Internal thermal overload protection
- Internal short circuit current limiting
- Output transistor safe-area compensation
- 4% Output voltage tolerance
