It has an adjustable output voltage up to 1.35V and a maximum current of up to 5 Amps. With its ultra-low operating current and wide range of operating temperature, this linear voltage regulator can easily maintain good performance across the operating range.

Working Principle

The ISL9012IRJMZ is a Linear Voltage Regulator designed to provide the lowest possible electrical noise when working in its operating range. Its high power density and fast transient response make it ideal for many applications. Its maximum output current can be programmed by connecting an external resistor to the TN pin, which is used to control the current.The linear voltage regulator works on the principle of two physics laws of electron motion, namely voltage divider and current divider. The voltage divider law states that an electrical signal can be divided into two parts, depending on the resistance and impedance of the components forming the signal path. The current divider law states that the current flowing in an electrical signal can be equally divided among the components if the resistance and impedance of the components is the same.For the ISL9012IRJMZ, both the voltage and current dividers are used to provide higher efficiency. The voltage divider helps to reduce the power dissipation by reducing the difference between the input and output voltages. The current divider reduces the amount of power needed to generate a given output current by dividing the current equally among the components.

Conclusion

ISL9012IRJMZ is an excellent linear voltage regulator for applications that require a high power density and fast transient response time. With its adjustable output voltage and maximum current, it is suitable for a wide range of applications and can easily maintain good performance across its operating range. This linear voltage regulator works on the principle of voltage and current dividers, and its design helps to enhance the efficiency of the system.
