NTE NTE1913

NTE1913
Integrated Circuit
Negative 3 Terminal Voltage Regulator,
–5V, 1.5A
Description:
The NTE1913 is a 3 terminal fixed negative voltage regulator in a TO3 type package suitable for numerous applications requiring up to 1.5A. This device employs internal current limiting safe area protection
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.
Features:
D Thermal, Short Circuit, and Safe Area Protection
D High Ripple Rejection
D 4% Preset Output Voltage

Note 2. Regulation is measured at a constant temperature by pulse testing with a low duty cycle.
Change in output voltage due to heating effects must be taken into account.
