Review NATIONAL SEMICONDUCTOR Semi 5a Adjustable Voltage Regulator Steel Body Military Grade
The LM138K, produced by National Semiconductor, is a robust and reliable 5-volt linear voltage regulator. This military-grade semiconductor device is housed in a robust steel body, making it suitable for various high-stress and high-reliability applications.
The LM138K is a 7-pin DIP (Dual In-line Package) integrated circuit. It is a monolithic voltage regulator that provides seven individual 5-volt outputs, each capable of delivering up to 150 milliamperes of current. This makes it an excellent choice for applications that require multiple low-current voltage supplies.
The LM138K features a wide input voltage range of 7 to 36 volts, ensuring flexibility in power sources. It also has a single adjustable voltage setting, which can be easily adjusted using an external resistor. The device is equipped with thermal shutdown protection, ensuring safe operation by turning off the output if the junction temperature exceeds the set limit.
The LM138K is designed to have a low noise output, with a typical output noise of less than 5 millivolts rms. It also has a high input and output impedance, ensuring minimal load effects and power supply ripple. The device can operate over a wide temperature range of -55 to 150 degrees Celsius, making it suitable for various environmental conditions.
In summary, the LM138K is a high-performance 5-volt linear voltage regulator that offers multiple low-current outputs, wide input voltage range, adjustable output voltage, thermal shutdown protection, low noise output, and high impedance. Its robust steel body and military-grade specifications make it an excellent choice for high-stress and high-reliability applications.
