BH28NB1WHFV-TR Integrated Circuits (ICs)

BH28NB1WHFV-TR is a linear voltage regulator of Power Management Integrated Circuit (PMIC) family, specially designed for protecting electronic components from the harmful excessive amounts of voltage. This efficient regulator ensures that the voltage produced by the power source remains constant, protecting all the internal and external circuits from overvoltage conditions.

Principle of Operation

At the core of BH28NB1WHFV-TR is an error amplifier, which is responsible for regulating the output voltage by using the difference between the desired output voltage and the actual voltage output by the regulator. It takes the feedback signal from the output voltage and uses it to compare the output voltage to the reference voltage. The internal power transistor then adjusts the output voltage to the desired level by controlling the current that passes through it. This system ensures that the output voltage remains constant.

Application Field

The BH28NB1WHFV-TR is mainly used in applications where low voltage is required such as in low voltage computers, embedded systems, automotive applications, telecommunications and consumer electronic products. It is also suitable for bipolar and MOSFET linear voltage regulation.

The BH28NB1WHFV-TR can operate in a wide range of working conditions. Its operating temperature range is -40°C to +85°C and its output voltage range is 0.6V to 16V. This wide voltage range makes it ideal for applications requiring low-voltage supplies. Its current rating is up to 3A and it has a power dissipation of 4W. Its low quiescent current consumption of 1mA at 3V output makes it a power efficient choice.
