TCR3UG50B,LF is a voltage regulator device belonging to the PMIC (Power Management Integrated Circuit) family. Specifically, the device is categorized under the Voltage Regulators - Linear subgroup. The device is manufactured, distributed, and sold by ROHM Co. Ltd, a Tokyo, Japan-based leader in the semiconductor and device industry.

The TCR3UG50B,LF is a low-dropout (LDO) 3A voltage regulator that is optimized for operation with low quiescent current (I_Q) and low minimum dropout voltage. The device provides a low-noise, low-ripple output even with a very low quiescent current and can be used in a wide range of applications, from general-purpose voltage regulation to management of digital power supply.

The TCR3UG50B,LF can deliver up to 3 A of continuous output current at up to 1.5 V in steps of 50 mV. The device has a wide input voltage range of 1.8 V to 6 V, making it suitable for use in a variety of configurations. The TCR3UG50B,LF can handle load transients while maintaining a stable output voltage, as well as provide a maximum of 80 dB of power supply rejection ratio (PSRR). The device is also capable of providing up to 1.5 µA of quiescent current, which makes it a great choice for battery-powered systems.

The TCR3UG50B,LF also comes with a wide range of features that enable its use in a variety of applications. These features include high accuracy of ±0.75 %, an output voltage range of 0.8 V to 1.5 V (in steps of 50 mV), low start-up delay of 10 µS, low temperature coefficient of ±2 mV/°C, and power on reset circuitry for a reliable start-up. The device also provides thermal shutdown circuit, over-current protection, and over-voltage protection for additional safety and reliability.

The TCR3UG50B,LF is designed to meet the PowerManagement IC (PMIC) - Voltage Regulators - Linear device category. The working principle of the device is based on the basic laws of electricity, and more specifically, it uses the characteristics of Voltage, Current and Resistors. This is termed linear regulation because the output is controlled by adjusting the input voltage and/or current to the device. For example, when the TCR3UG50B,LF is used as a voltage regulator, the input voltage is adjusted to maintain a constant output voltage.

In conclusion, the TCR3UG50B,LF from ROHM Co. Ltd is a 3 A linear voltage regulator that is designed for a wide range of applications. The device’s wide input voltage range, low quiescent current, high accuracy, and low temperature coefficient make it an attractive choice for many scenarios. Furthermore, the device features additional features such as over-voltage and over-current protection, thermal shutdown circuit, and power on reset circuitry.
