The TCR2DG31 is an NSVF linear voltage regulator designed for use in PMIC applications such as power management. It provides a low-noise, low-dropout voltage solution to extend battery life and reduce system-level heat dissipation. This device is a low-power, low-dropout linear regulator, offering a low 500uA quiescent current in a variety of package options.The TCR2DG31 is offered in a choice of three fixed output voltages, 5V, 3.3V and 1.8V, each version with a ±2% regulation tolerance. The regulator features an input voltage range of 4.5V to 17V and an output current up to 250mA. This device has several operational characteristics that make it an attractive option for applications where higher output current is not required. The low noise operation, low operating current and available packages make this device ideal for use in portable equipment.The TCR2DG31 is an adjustable type of regulator, with the output voltage selected by an external resistor divider connected between the output pin and the adjust pin. In this way, the user can adjust the voltage to any value within the range of 1.5V and 24V. The device also features short circuit protection, inrush current limiting, thermal shutdown protection and output voltage trimming, providing a safe operation from start to finish.The working principle of the TCR2DG31 is to prepare and condition the power supply for use in the system. The input voltage is stepped down to an adjustable, regulated voltage, and is then transmitted to the components and devices in the system. The linear regulator acts as an electronic switch, opening and closing to allow a constant, regulated voltage to be supplied to the load. When the load current increases, the regulator senses these changes and increases the gate voltage to bring the output voltage back to the desired level.In summary, the TCR2DG31 is a low-dropout linear voltage regulator designed to provide a range of features and performance benefits for PMIC applications. It offers a wide input voltage range, adjustable output voltage and low noise operation. The device has been designed to work efficiently to extend battery life and reduce power dissipation, making it a great choice for applications that require low-power voltage regulation.
