( Brand: Linear ), ( Manufacturer Part Number: LT1074HV ), ( Part Type: Voltage Regulator )
The LT1074HV is a high voltage linear voltage regulator designed to provide stable and precise voltage regulation in power supply applications. This device is ideal for use in applications requiring a maximum input voltage of 60V and an output voltage of 22.5V.
The LT1074HV is a three-terminal linear regulator, featuring an input (VIN), output (VOUT), and ground (GND) terminal. It is equipped with a built-in over-current protection mechanism, which helps to prevent damage to the device due to excessive current flow. The device also has a thermal shutdown feature, which automatically turns off the output when the junction temperature exceeds a specified limit, ensuring the safety of the device and the connected load.
The LT1074HV is designed with a high output current capability, allowing it to deliver up to 1A of output current. It has a low dropout voltage of 3V, which means it can maintain a stable output voltage even when the input voltage drops below the regulated output voltage. The device also has a high power supply rejection ratio (PSRR), making it less sensitive to input voltage noise and ensuring a clean and stable output voltage.
The LT1074HV is housed in a small SOT-223 package, making it easy to integrate into a wide range of applications, from mobile devices to industrial power supplies. It is also available in a leadless surface-mount package, making it suitable for automated assembly processes.
In summary, the LT1074HV is a high voltage linear regulator that offers stable and precise voltage regulation, high output current capability, and robust protection features. Its small package size and high PSRR make it an ideal choice for a wide range of power supply applications.
Pros of buying LT1074HV 22.5V Linear Regulator:1. High Efficiency: The LT1074HV has a typical dropout voltage of 1.5V at 1A, which means it can deliver a steady output even when the input voltage drops.
2. Wide Input Voltage Range: It can operate over a wide input voltage range of 10V to 36V, making it suitable for various power supply designs.
3. Low Noise: The LT1074HV has a typical noise of 50 V p-p, which is quite low, making it suitable for noise-sensitive applications.
4. Wide Output Voltage Adjustment Range: It can provide an adjustable output voltage from 2.5V to 28V.
5. Overvoltage Protection: It has built-in overvoltage protection, which protects the regulator and the load from damage due to overvoltage.
Cons of buying LT1074HV 22.5V Linear Regulator:1. Lower Power Dissipation: Compared to switching regulators, linear regulators like LT1074HV have lower power dissipation capabilities.
2. Lower Efficiency at Low Loads: Linear regulators like LT1074HV are less efficient at low loads, which can result in a significant amount of heat being generated.
3. Bulkier Size: Linear regulators like LT1074HV are generally bulkier than switching regulators, making them less suitable for space-constrained applications.
4. Lower Output Current: The LT1074HV can provide a maximum output current of 1A, which may not be sufficient for high current applications.
Conclusion:The LT1074HV 22.5V Linear Regulator is a high-performance regulator that offers a wide input voltage range, low noise, and overvoltage protection. However, it has lower power dissipation, lower efficiency at low loads, a bulkier size, and a lower maximum output current compared to switching regulators. Therefore, if you need a regulator for a high current application or a space-constrained design, a switching regulator may be a better option. However, if you require a regulator with a wide input voltage range, low noise, and overvoltage protection, the LT1074HV 22.5V Linear Regulator is a great choice.
Recommendation:If you require a regulator with a wide input voltage range, low noise, and overvoltage protection, the LT1074HV 22.5V Linear Regulator is a great choice. However, ensure that your application can accommodate its lower power dissipation, lower efficiency at low loads, bulkier size, and lower maximum output current. If you need a regulator for a high current application or a space-constrained design, consider a switching regulator.
30 day warranty. Regardless, after the war, the airlines stayed with the military tradition of using yellow tags as a serviceable item.
For avionics repairs call avionics masters at yellow tag vs.
Regardless of the fact that there are logbooks out there that are full of them, the term yellow tag isn't mentioned anywhere in far part 43. Ital a myth and few yellow tags provide the information required by the FAA.
The only FAA approved maintenance release under far part 43, appendix b is the FAA form a yellow tag does not provide any of the requirements for the return to service for avionics components. Most of us would have picked the color green for serviceable and yellow for repairable not the other way around.
