Description:

The NTE1910 is a 3 t erminal fixed positive voltage r egulator i n a TO220 type package. S tabilized f ixed
output voltage is obtained from unstabe DC input voltage without the use of external components.

Features:

D No External Components
D Output Current in Excess of 1A
D Internal Short–Circuit Current Limiting
D Internal Thermal Overload Protection
D Output Transistor Safe Area Compensation

Coefficient

Note 1. The specified condition, TJ = +25°C, means that the test should be carried out with the test

time so short (within 10ms) that the drift in characteristic value due to the rise in chip junction
temperature can be ignored.
