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 numer- ous 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 resist- er 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.

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. .135 (3.45) Max .350 (8.89) .875 (22.2) Dia Max Seating Plane .312 (7.93) Min .040 (1.02) V 1.187 (30.16) OUT .215 (5.45) .665 (16.9) .156 (3.96) Dia (2 Holes) .430 (10.92) .188 (4.8) R Max .525 (13.35) R Max GND V /Case IN
