Power management integrated circuits (PMICs) enable processor nodes in an integrated circuit (IC) system to perform their duties in an efficient and reliable manner. The LT1461CCS8-3#TRPBF, manufactured by Linear Technology, is a voltage reference series that can be used to stabilize output voltages, monitor power in critical circuits, support microprocessor-based systems, and ensure optimal conditions for reliable IC system operation. This article provides a description of the LT1461CCS8-3#TRPBF application field and its working principle, as well as thermal imaging of its package.

Application Field

The LT1461CCS8-3#TRPBF is designed for use in a wide range of applications such as audio systems, computer and communication equipment, lighting and power supply systems, automotive electronics, and more. In all these systems, the LT1461CCS8-3#TRPBF voltage reference series can be used to ensure that the system operates with stable and reliable output voltages. Furthermore, in these applications, the series can be used to provide precision tracking and regulation of the output voltage, while providing protection to power supplies against over or under voltage conditions.

The LT1461CCS8-3#TRPBF series is specifically designed for microprocessor-based systems, and offers a high accuracy of up to ±3% initial accuracy. Its low drop-out voltage ensures clean power for all microprocessor-based systems. Additionally, the series also features low power consumption, typically only 0.2 microamperes of total current. This power efficient design reduces the power drain and allows for more efficient system performance.

Working Principle

The LT1461CCS8-3#TRPBF series is a voltage reference, in which the output voltage is referenced against an internal reference. This reference is typically a bandgap or Zener diode, which is extremely stable, and also immune to temperature and other environmental influences. The output voltage of the voltage reference is regulated by an internal comparator which is regulated against the reference. The comparator is powered by this input voltage.

When the voltage across the comparator is lower than the reference voltage, the comparator will turn on the drive transistor which increases the output voltage. Once the output voltage reaches the reference voltage, the comparator is turned off and the output voltage does not increase any further. The comparator also monitors the output voltage for any drops which may be caused due to high load currents. If the output voltage drops, the comparator will turn on the drive transistor again and restore the output voltage to the reference voltage.

Thermal Imaging of Package

The LT1461CCS8-3#TRPBF package is small, measuring in at only 3x3x2 millimeters, but is considered very robust. Its hermetic SOT-23 package has a high thermal conductivity, ensuring efficient cooling and thermal dissipation. The package is built with gold-plated contacts, ensuring that the voltage reference can provide a strong connection without fuss. Thermal imaging of the LT1461CCS8-3#TRPBF package reveals that it is thermally efficient and can keep itself cool even under rigorous conditions.

Conclusion

The LT1461CCS8-3#TRPBF voltage reference series, manufactured by Linear Technology, can be used in a variety of applications to ensure stable output voltages, precision tracking and regulation, protection from over and under voltage conditions, low power consumption, and robustness. Its hermetic SOT-23 package has a high thermal conductivity that enables efficient cooling, and thermal imaging reveals that it is thermally efficient as well. With all of these features, the LT1461CCS8-3#TRPBF can provide reliable performance in critical power management applications.
