NTE NTE1910

NTE1910
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
9V, 1A
Description:
The NTE1910 is a 3 terminal fixed positive voltage regulator in a TO220 type package. Stabilized fixed
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
Absolute Maximum Ratings: (TA = 25°C unless otherwise specified)

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.
Note 2. When not specified, VI = 15V, IO = 500mA, CI = 0.33µf, and CO = 0.1µf.
