NTE NTE1913 Datasheet
NTE1913
Integrated Circuit
Negative 3 Terminal Voltage Regulator,
–5V, 1.5A
Description:
The NTE1913 i s a 3 t erminal fixed negative voltage regulator in a TO3 type package suitable for numerous applications r equiring u p t o 1 .5A. This device employs i nternal c urrent l imiting s afe a rea p rotection
and thermal shutdown for protection against virtually all overload conditions.
Low ground pin current allows output voltage to be easily boosted above the preset value with a resister divider. The low quiescent current rain of the NTE1913 with a specified maximum change with line
and load ensures good regulation in the voltages boosted mode.
