NTE960

NTE960 Integrated Circuit 3–Terminal Positive Voltage Regulator, 5V The NTE960 fixed–voltage regulator is a monolithic integrated circuit in a TO220 type package designed for use in a wide variety of applications including local, on–card regulation. This regulator employs internal current limiting, thermal shutdown, and safe–area compensation. With adequate heatsinking it can deliver output currents in excess of 1.0 ampere. Features: D Output Current in Excess of 1.0 Ampere D No External Components Reguired D Internal Thermal Overload Protection D Internal Short–Circuit Current Limiting D Output Transistor Safe–Area Compensation Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Input Voltage, Vin . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35Vdc Power Dissipation (TA = +25°C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. Electrical Characteristics (Cont’d): (Vin = 10V, IO = 500mA, TJ = 0° to +125°C unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Quiescent Current IB TJ = +25°C – 4.3 8.0 mA Quiescent Current Change ∆IB 7V ≤ Vin ≤ 25V – – 1.3 mA 5mA ≤ IO ≤ 1A – – 0.5 mA 8V ≤ Vin ≤ 18V, f = 120Hz – 68 – dB TJ = +25°C, IO = 1A – 2 – V Ripple Rejection RR Dropout Voltage Vin – VO Output Noise Voltage Vn TA = +25°C, 10Hz ≤ f ≤ 100kHz – 10 – µV/VO Output Resistance rO f = 1kHz – 17 – mΩ Short–Circuit Current Limit Isc TA = +25°C, Vin = 35V – 0.2 – A TJ = +25°C – 2.2 – A – –1.1 – mV/°C Peak Output Current Imax Average Temperature Coefficient of Output Voltage TCVO .420 (10.67) Max .110 (2.79) GND .147 (3.75) Dia Max .500 (12.7) Max .250 (6.35) Max .500 (12.7) Min .070 (1.78) Max VIN .100 (2.54) VOUT GND
