Linear Voltage Regulators are one of the most common and important components used in a wide range of power management systems. Typically their role is to regulate the output voltage to match a given DC input voltage. One of the main advantages of linear voltage regulators is the lack of electromagnetic interference (EMI) generated by the voltage regulator, avoid which can enable the use of smaller and less costly components, such as transformers and inductors. The TCR3DM285 is a common low-noise Linear Voltage Regulator that is used in a variety of fields of application.

The TCR3DM285 is designed for low-noise (<50µV) linear voltage regulation with a wide input operating range from 4.5V to 18V. Its output voltage is adjustable from 0.6V to 24V and can provide up to 1.5A of current. The device is housed in the SOT23-3 package, ideal for space constrained applications. A key feature of the TCR3DM285 is its low-noise LF (low-frequency) operation with a voltage ripple of <20mV, enabling the use of high-load DC/DC converters. As it is built to meet the requirements for compliant EMI and EMC (electromagnetic compatibility) standards, the device meets the standard for automotive applications as well as industrial and consumer applications.

The TCR3DM285 is also designed for flexibility and efficiency, allowing for dynamic switching between Step-up and Step-Down functionality, as well as allowing for a maximum of 6 adjustable output voltages in a single output mode. The device also features a low-voltage cutoff for protection against overload and over current, as well as a soft start function for an efficient and quieter startup. Additionally, the TCR3DM285 includes a reverse current protection to protect against short circuit in the case of output short circuit.

The working principle of the TCR3DM285 Linear Voltage Regulator is based on a voltage-current difference that occurs between the input and output sides of the device. As the input voltage increases, the difference between the output and the input voltage is reduced and thus, the load current is reduced. When the output voltage is greater than the input voltage, the output current increases accordingly. This process continues until the output current reaches the maximum allowable current of the device.

The output voltage adjustment is done by altering the resistor values. The output voltage is adjusted by setting the resistor values provided in the TCR3DM285 datasheet. The output voltage is then adjusted to the desired level based on the resistor values. The regulation of the output voltage is set to achieve the required output current limit and to help maintain the device stability over its entire operating range.

Overall, the TCR3DM285 Linear Voltage Regulator is a high-performance, low-noise, low-cost voltage regulator that is suitable for a broad range of fields and applications. It is designed to provide a high level of efficiency and flexibility as well as meeting the requirements of compliant EMI and EMC standards. It includes a range of features such as low-voltage cutoff, reverse current protection, and soft start function, making it an ideal choice for space-constrained applications.
