NTE1932 Integrated Circuit 3Terminal Positive Voltage Regulator, 10V, 1A The NTE1932 fixedvoltage regulator is a monolithic integrated circuit in a TO220 type package de- signed for use in a wide variety of applications including local, oncard regulation. This regulator em- ploys internal current limiting, thermal shutdown, and safearea compensation. With adequate heat- sinking it can deliver output currents in excess of 1.0 ampere. Although designed primarily as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.

Load and line regulation are specified at constant junction temperature. Changes in V due O to heating effects must be taken into account separately. Pulse testing with low duty cycle is used.Electrical Characteristics: (V = 16V, I = 500mA, C = 0.33F, C = 0.1F, T = 0 to +125C in O I O J unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Quiescent Current I T = +25C 4.3 8.0 mA B J Quiescent Current Change I 12.5V V 29V 1.0 mA B in 5mA I 1A 0.5 mA O Ripple Rejection RR 14V V 23V, f = 120Hz 56 71 dB in Dropout Voltage V V T = +25C, I = 1A 2 V in O J O Output Noise Voltage V T = +25C, 10Hz f 100kHz 58 V/V n A O Output Resistance r f = 1kHz 17 m O ShortCircuit Current Limit I T = +25C, V = 35V 420 mA sc A in Peak Output Current I T = +25C 2.2 A max J .420 (10.67) Max .110 (2.79) .147 (3.75) Dia Max .500 (12.7) Max .250 (6.35) Max .500 (12.7) Min .070 (1.78) Max V V IN OUT .100 (2.54) GND/Tab
