NTE NTE1271

NTE1271
Integrated Circuit
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.
Features:
D No Need for External Components
D Three Outputs @ 8.2V typ
D Noise Protection Circuitry
D Overload Current Protection and Thermal Protection Circuitry
D Good Mountability
D High Output Current: 200mA typical for VO2 output
100mA typical for VO0, VO1 outputs

Note 1. 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.
