NTE1271

Control Voltage Generator Description: The NTE1271 control voltage generator with three outputs is fabricated with bipolar linear technology. Two alternately exchangeble outputs are provided for two stabilized output levels controlled by an external signal. The NTE1271 is packaged in a 8−Lead SIP package with a heat radiation fin to allow for large power dissipation.

Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should be restricted to the conditions as detailed in the operational sections of the data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
