Description

The NTE950, NTE951, and NTE977 are positive 3terminal voltage regulators in available in a TO92 type package.  With adequate heat sinking these regulators can deliver 100mA output current.  Cur-rent limiting of NTE951 is included to limit peak output current to safe value.  Safe area protection for the output transistors is provided to limit internal power dissipation.  If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from overheating.

When used as a zener diode/resistor combination replacement, these NTE951 usually result in an ef-fective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation.  Typical applications of NTE951 include use in logic systems, instrumen-tation, HiFi, and other solid state electronic equipment.  Although designed primarily as fixed voltage regulators these NTE951 can be used with external components to obtain adjustment voltages and currents.
