NJM78LR05BU-TE1 Application Field and Working Principle

The NJM78LR05BU-TE1 is a BIPOLAR LINEAR VOLTAGE REGULATOR, which belongs to the PMIC (Power Management IC) voltage regulators product family of NJM Semiconductors. It is used as a 3-terminal, 500 mA , 5V low-dropout regulator that is designed to consume minimum power and space while still delivering excellent line/load regulation and low noise performance.

NJM78LR05BU-TE1 is also offered in extended temperature of up to −40°C to +125°C, making it ideal for applications that require high reliability and superior performance in extreme temperature environments. Additionally, the device provides short-circuit and overheating protection for maximum safety and reliability.

NJM78LR05BU-TE1 Application Field

The NJM78LR05BU-TE1 is a low-operating current and low-dropout voltage regulator, with a maximum output current of 500 mA, which makes it well suited for a variety of applications, such as in battery-powered systems, car audio systems, LCD drivers, server system power supplies, and portable industrial and medical instruments. As it only requires a small input to output differential, the NJM78LR05BU-TE1 can be used as well as an auxiliary voltage regulator device in any application requiring a heavily filtered and regulated voltage.

NJM78LR05BU-TE1 Working Principle

The NJM78LR05BU-TE1 has an internal voltage reference, an error amplifier, an output driver, and current limiting circuit. It works by comparing an internally generated voltage reference to an external voltage reference and then adjusting the output voltage by controlling the amount of current supplied to the output. The external voltage reference sets the desired voltage, while the internally generated reference sets the actual output voltage. The errors amplifier continuously calibrates the two so that the output voltage remains as close to the desired voltage as possible. Once the excess load current is identified, the current limiting circuit in the NJM78LR05BU-TE1 cuts off the supply, limiting the damage that may be caused by the excessive current.

Conclusion

The NJM78LR05BU-TE1 is a high-performance, low-dropout, 500 mA regulator for use in a wide range of applications. Its unique design ensures maximum efficiency, stability and short circuit protection. The device also offers protection against thermal runaway and allows for reliable operation over a wide temperature range of -40°C to +125°C. Additionally, its inherently low quiescent current and low voltage dropout make it ideal for use in battery-operated systems.
