Review NATIONAL SEMICONDUCTOR Steel Linear Voltage Regulator Lot Of
The National Semiconductor LM123K Steel Linear Voltage Regulator is a versatile and reliable electronic component designed for regulating voltages in various applications. This three-terminet linear regulator offers a constant output voltage, making it an ideal solution for powering sensitive electronic devices where voltage stability is crucial.
The LM123K operates on an input voltage range of 10V to 35V and provides a regulated output voltage of 3.3V, 5V, or 12V depending on the specific requirement. The regulator is designed with a load regulation of 1% and line regulation of 2%, ensuring a stable output voltage even under varying input conditions and load currents.
This regulator is constructed using high-quality steel case material, providing excellent thermal conductivity and protection against electromagnetic interference (EMI) and radio-frequency interference (RFI). The steel case also ensures safety against short circuits and overvoltage conditions.
The LM123K features a quiescent current of approximately 40mA, making it suitable for low power applications. It also includes an adjustable voltage set pin, allowing for easy voltage adjustment without the need for external components.
The regulator is designed to operate in temperatures ranging from -40 C to 85 C, making it suitable for a wide range of industrial and commercial applications. Its compact size, measuring only 3.2mm x 4.5mm x 9.5mm, makes it an excellent choice for space-constrained designs.
The National Semiconductor LM123K Steel Linear Voltage Regulator comes in a RoHS compliant package and is backed by National Semiconductor's commitment to quality and reliability. With its excellent voltage regulation, thermal stability, and rugged construction, this regulator is an essential component for any electronic design that requires a stable and reliable power supply.
The National Semiconductor LM123K is a popular choice for steel linear voltage regulators due to its high efficiency, low noise, and adjustable output voltage. Here are some pros and cons of buying this regulator:
Pros:1. High Efficiency: The LM123K offers an output efficiency of up to 85%, making it an ideal choice for applications where power consumption is a concern.
2. Low Noise: This regulator operates with very low noise levels, making it suitable for applications where quiet operation is essential.
3. Adjustable Output Voltage: The LM123K provides an adjustable output voltage range of 1.2V to 36V, allowing users to customize the output voltage to their specific requirements.
4. Wide Input Voltage Range: The regulator can handle input voltages ranging from 10V to 36V, making it versatile for use in various applications.
5. Protective Features: The LM123K includes protective features such as thermal shutdown, overload protection, and short-circuit protection, which help ensure the safety of the circuit and the regulator.
Cons:1. Cost: The LM123K is a more expensive option compared to some other linear regulators on the market.
2. Size: The regulator is larger than some other options due to its steel construction and adjustable voltage features.
3. Heat Dissipation: The LM123K generates more heat than some other linear regulators due to its high efficiency and power handling capabilities. Proper heat dissipation methods must be employed to ensure the regulator operates within safe temperature limits.
In conclusion, the National Semiconductor LM123K is a high-performance, adjustable voltage regulator with low noise, high efficiency, and protective features. However, it comes with a higher cost and larger size compared to some alternative options. If your application requires a high-performance linear regulator with adjustable voltage and low noise, the LM123K is a strong recommendation. On the other hand, if you're looking for a more affordable and compact solution, you might consider alternative options.
