PMIC (Power Management Integrated Circuits) are widely used in the production of various electronic devices, especially for those requiring specific current and voltage ratings. Voltage-reference parts such as the LT1004IDRE4-2-5 are among the most popular for their precision and accuracy. In this article, we will discuss the application field and working principle of the LT1004IDRE4-2-5, a voltage reference from Linear Technology Corporation (Linear Tech).
The LT1004IDRE4-2-5 is a low-power, 4-terminal, precision voltage-reference device that shares many of the features of other voltage references in Linear Tech’s family of products, but with the added benefit of an internal diode-connected load. This device is designed using an innovative CMOS technology with precision trimmed thin-film resistors and a poly-silicon bandgaps to stabilize the output voltage. Featuring a high temperature stability and a low dynamic output impedance, it has a low input current, providing a high gate-source break down voltage ensuring a long operating life. It is available in several temperature ranges, including the –55°C to +125°C range, perfect for industrial applications.
The LT1004IDRE4-2-5 provides a precise TTL voltage reference with a relatively high output current capability. It has an output voltage that can be adjusted either up or down in approximately 0.2V increments from a nominal 4.2V output voltage. This allows it to be used as a voltage shifter or source for a digital circuit. Its full operating range (4.2V - 5.4V) allows its output voltage to range from 0.2V to nearly 5V - even allowing the device to generate up to 500mA of output current. A dedicated pin controls the current limitation of the device, allowing it to be accurately adjusted to customer specifications regardless of output current requirements.
The LT1004IDRE4-2-5 voltage reference works by means of feedback. It works in a similar fashion to many fixed-output regulators, by sensing the output of the device and adjusting the current through the internal diode-connected load to maintain the desired output voltage. This feedback system ensures that the regulated voltage output is highly stable and precise. On the other hand, the device works as a shift regulator, rapidly changing the output voltage in small increments by adjusting the current through the internal diode-connected load.
The LT1004IDRE4-2-5 is well suited for use in industrial applications, such as analog-to-digital converters, automotive systems, telecom systems, and power supplies. Its wide operating temperature range and its high stability make it an excellent choice for any system requiring precise and accurate voltage control. It is highly reliable, providing a solution that is stable over time and temperature. Furthermore, its extended life and minimal power consumption make it a very attractive solution for many industrial applications.
In conclusion, the LT1004IDRE4-2-5 is a versatile and reliable voltage reference from Linear Tech’s family of products. Its combination of precision and accuracy make it a great solution for industrial applications that require precise and stable voltage control. It is highly reliable and its extended life and minimal power consumption make it a very attractive solution for many industrial applications.
