Key Features

• 4 channels of 5V output with minimal output voltage drops
• Programmable current limit and over-voltage protection
• Flexible thermal characteristics
• SMD ceramic package with integrated heat sink

Applications

The ADP1740ACPZ-0.75R7 is designed to withstand high temperature environments and power fluctuations, making it suitable for transportation applications like Automotive and Aerospace, as well as automotive accessories, printing machinery, and computer and networking equipment. Because of its robust design, it is well suited for applications where constant temperatures and power supplies are not reliably met. It is capable of handling both 12V and 24V supplies, and outputs can be set up to 5V with minimal drops in voltage.

Working Principle

At its core, the ADP1740ACPZ-0.75R7 is a linear voltage regulator, meaning that it reduces the input voltage as needed. This is accomplished by using a three terminal device such as a Transistor, SCR, or FET as the input for the regulator. The input voltage is converted to a reference voltage which is compared to the output voltage via an error signal. If the output voltage is below the reference voltage, then the input voltage is increased. Conversely, if the output voltage is above the reference voltage, the input voltage is decreased. This continues until the output voltage is stable, at which point the regulator is said to be operating in a “steady state.”

Conclusion

The ADP1740ACPZ-0.75R7 is a specialized linear voltage regulator designed to operate in highly demanding, high temperature environments. Its SMD ceramic package with an integrated heat sink makes it ideal for transportation applications such as automotive and aerospace, as well as for computing and networking. It can be used to output up to 5V with minimal drops in voltage, and is capable of handling both 12V and 24V supplies. With its wide range of features and robust design, the ADP1740ACPZ-0.75R7 is a great choice for any application requiring reliable power regulation.
