Introduction

Mains IC39150-1.65BT is a linear regulator designed for use in electronic systems which are powered by low-voltage input sources of up to 18V. This voltage regulator, like any other linear voltage regulator, is designed to produce a constant regulated voltage output when used in the power supply of a device. It is a simple, cost-effective solution to regulate and stabilize the supply voltage in equipment, while also doing its part to reduce heat generated by the voltage source.

Application Field

The MIC39151-1.65BT is rated for an output current of up to 1.65A, making it suitable for optimally supplying voltage to components such as sensors, actuators, and microcontrollers that require low current, yet consistent power. It is ideal for applications such as battery-powered devices, medical and industrial equipment, test and measurement instruments, and automotive systems.

Design and Working Principle

This voltage regulator is comprised of several passive components such as resistors and capacitors in addition to signal transistors. It makes use of an \'error amplifier\' as feedback circuit to regulate the output voltage. This amplifier monitors the voltage level of both the reference voltage and output voltage and compares the two to modify the output voltage appropriately. The reference voltage is preset at the 1.65V desired level, but this voltage can be adjusted via the adjustment pin if required.The Mains IC39150 regulator is driven by an internal oscillator, which is used to prevent the power supply from generating noise and muffling other electronic circuits. The oscillator has a frequency of 1MHz and its primary tasks is to regulate the current loop, which helps to prevent any excessive current spikes and jerks on the output side. The linear regulator is also designed to achieve a high output voltage accuracy of 0.3% or better. The input capacitor of the Mains IC39150-1.65BT voltage regulator is used to store energy and ensure the input voltage is stable before regulation. The output capacitor helps to minimize output voltage disturbances and ripple due to changes in the input voltage.

Conclusion

The Mains IC39150-1.65BT linear voltage regulator offers a reliable, cost-effective way to deliver consistent power to multiple components at once. This voltage regulator offers excellent protection from high-voltage and current surges and its oscillator helps prevent system noise from interfering with other circuitry. With its high level of accuracy, it can easily be adjusted to precisely regulate any voltage requirements.
