| NTE1915 Integrated Circuit Negative 3 Terminal Voltage Regulator -12V, 1.5A Description: The NTE1915 is a 3 terminal negative regulator in a TO3 type package with a fixed output voltage of -12V and up to 1.5A load current capability. Where other voltages are required, the NTE1911 provides an output voltage range of -1.2V to -37V. This device needs only one external component - a compensation capacitor at the output, making it easy to apply. Worst case guarantees on output voltage deviation due to any combination of line, load, or temperature variation assure satisfactory system operation. Exceptional effort has been made to make the NTE1915 immune to onerload conditions. This regulator has current limiting which is independent of temperature, combined with thermal overload protection. Internal current limiting protects against momentary faults while thermal shutdown prevents junction temperatures from exceeding safe limits during prolonged overloads. Although primarily intended for fixed output voltage applications, the NTE1915 may be programmed for higher output voltages with a single resistive divider. The low quiescent drain current of the device allows this technique to be used woth good regulation.

Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account separately. To ensure constant junction temperature, low duty cycle, pulse testing is used. The NTE1915 does have low thermal feedback, improving line and load regulation. On all other tests, even though power dissipation is internally limited, electrical specifications apply only up to PD. .135 (3.45) Max .350 (8.89) .875 (22.2) Dia Max Seating Plane .312 (7.93) Min VOUT .215 (5.45) .040 (1.02) 1.187 (30.16) .665 (16.9) .156 (3.96) Dia (2 Holes) .430 (10.92) .188 (4.8) R Max GND .525 (13.35) R Max VIN/Case |
