NTE1914

NTE1914 3 Terminal Positive Voltage Regulator 12V, 1A Description: The NTE1914 is a positive 3–terminal voltage regulator in a TO3 type package suitable for numerous applications requiring up to 1A. One of these is local on card regulation, eliminating the distribution problems associated with single point regulation. Other applications include; logic systems, instrumentation, HiFi, and other solid state lectronic equipment. Although designed primarily as a fixed voltage regulator, the NTE1914 can be used with external components to obtain adjustable voltages and currents.

All characteristics are measured with a 0.22µF capacitor across the input and a 0.1µF capacitor across the output. All characteristics except noise voltage and ripple rejection ratio are measured using pulse tecniques (tw ≤ 10ms, duty cycle ≤ 5%). Output voltage changes due to changes in internal temperature must be taken into account separately. Electrical Characteristics (Cont’d): (0° ≤ TJ ≤ +125°C, VO = 12V, VIN = 19V, Note 2 unless otherwise specified) Parameter Line Regulation Symbol Test Conditions Min Typ Max Unit – 4 120 mV – – 120 mV 15V ≤ VIN ≤ 27V, IO = 500mA – – 120 mV 16V ≤ VIN ≤ 22V, IO ≤ 1A – – 60 mV TJ = +25°C 5mA ≤ IO ≤ 1.5A – 12 120 mV – – 60 mV 5mA ≤ IO ≤ 1A – – 120 mV TJ = +25°C, IO ≤ 1A – – 8.0 mA IO ≤ 1A – – 8.5 mA 5mA ≤ IO ≤ 1A – – 0.5 mA TA = +25°C, IO ≤ 1A, 14.8V ≤ VIN ≤ 27V – – 1.0 mA IO ≤ 500mA, 14.5V ≤ VIN ≤ 30V – – 0.5 mA TJ = +25°C 14.5V ≤ VIN ≤ 30V, IO = 500mA Regline 14.6V ≤ VIN ≤ 27V, IO ≤ 1A Load Regulation Regload 250mA ≤ IO ≤ 750mA Quiescent Current Quiescent Current Change IQ IQ Output Noise Voltage Vn TA = +25°C, f = 10Hz to 100kHz – 75 – µV Ripple Rejection Ratio RR TA = +25°C, 15V ≤ VIN ≤ 25V, f = 120Hz, IO ≤ 1A 55 72 – dB 15V ≤ VIN ≤ 25V, f = 120Hz, IO ≤ 500mA 55 – – dB TJ = +25°C, IO = 1A – 2.0 – V TJ = +25°C – 2.4 – A IO = 5mA – 1.5 – mV/°C Dropout Voltage Peak Output Current IOmax Average Temperature Coefficient of Output Voltage Note 2.
