Description:
The NTE969 fixed-voltage regulator is a monolithic integrated circuit in a TO220 type package designed for use in a wide variety of applications including local, on-card regulation. This regulator employs internal current limiting, thermal shutdown, and safe-area compensation. With adequate heat sinking it can deliver output currents in excess of 1 amp. Although designed primarily as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.
Features:
- Output Current in Excess of 1A
- No External Components Required
- Internal Thermal Overload Protection
- Internal Short-Circuit Current Limiting
- Output Transistor Safe-Area Compensation
Absolute Maximum Ratings: (T
A = +25°C unless otherwise specified)
