NTE Electronics, Inc. Voltage Regulators - Linear NTE1974

The NTE1974 is a monolithic 3-terminal positive voltage regulator from Quarktwin Technology Ltd. It is designed to provide a fixed output voltage of 18V with an input voltage range of 21V to 33V. The device can deliver over 1A of output current when adequately heat-sinked and features internal current limiting, thermal shutdown, and safe-area compensation, enhancing its reliability and durability. The NTE1974 has a maximum power dissipation of 16W and operates within a junction temperature range of -30¬8C to +150¬8C. Its quiescent current is approximately 4.5mA at no load, and it exhibits load regulation of up to 180mV across a load current range of 0.005A to 1.5A. The line regulation is specified at 15mV for input variations within the specified range at a load current of 0.5A. Additionally, the NTE1974 provides ripple rejection of 59dB and an output noise voltage of 100¬µV, making it suitable for applications requiring stable voltage regulation with minimal noise. This regulator is ideal for local regulation in various electronic applications, particularly where space and efficiency are critical.
