EZ1585CM.TRT Application Field and Working Principle

EZ1585CM.TRT class is a type of linear voltage regulator in the area of Power Management Integrated Circuits (PMICs), which is typically used for applications such as power supply and various motor control, instrumentation and automotive applications. It is designed to support a wide range of input, output and thermal characteristics and features tight output voltage accuracy and very low dropout voltage.

EZ1585CM.TRT Features

The EZ1585CM.TRT voltage regulator is designed to serve both applications where input and output are sharing the same outer ground plane, and applications where input and output are only connected via a common source. Main feature of this type of PMICs is its a low dropout voltage; it also has tight output voltage accuracy, adjustable current-limit protection and thermal shutdown protection. It offers up to 1.5 Amps of output current and output voltages range from 1.2 Volts to the regulator’s input.

Other features include fast transient response, low thermal resistance, superior EMI performance, low output noise, easy to use standard components and wide operating temperature from -40°C to +85°C. Moreover, the EZ1585CM.TRT also features an internal 2-second soft-start circuitry that limits inrush current during start up, making it very convenient to use in many applications.

EZ1585CM.TRT Working Principle

Working principle of the EZ1585CM.TRT voltage regulator is based on a standard linear regulator design. It consists of a pass element, power transistor in this case, a reference voltage, and a feedback loop with a error amplifier included. Voltage is regulated by measuring the voltage between the output and ground. If the voltage between the output and ground does not match the specified voltage, the error amplifier produces an electrical signal proportional to the error. This signal is then amplified and used to control the power transistor, in turn regulating the output voltage.

The output voltage is adjustable by means of an external resistor connected to the adjust pin. This resistance adjusts the ratio between output voltage and reference voltage. When voltage at the adjust pin is lower than the regulated voltage, pass element open, enabling current to flow from the input to the output. When the voltage at adjust pin is higher than the regulated voltage, the pass element is closed, blocking current flow.

EZ1585CM.TRT Application Field

Due to its low dropout voltage, adjustable current-limit protection and thermal shutdown protection, EZ1585CM.TRT voltage regulators are used in a variety of applications where an accurate, stable output voltage is needed. It is primarily used for various motor control and instrumentation applications, as its output can be immediately adjusted as the motor starts or stops, ensuring an improved protection for the motor in these scenarios.

It is also primarily used in automotive applications, like automotive power supplies and automotive modules. It is also used in non-automotive applications, such as digital TVs, industrial lighting, and devices having multiple output power supply requirements. This type of PMICs is also suitable for use in industrial, communication, and computer applications, where tight regulation and low dropout voltage is required.

Conclusion

The EZ1585CM.TRT PMICs are very versatile, enabling them to be used in a wide range of applications. Its features, like adjustable current-limit protection, thermal shutdown protection and low dropout voltage, make it an ideal component for motor control, instrumentation, and automotive applications. Its low output noise, fast transient response and low thermal resistance allows it to be suitable for use in a variety of industrial, communication, and computer applications.
