UCC383TDTR-3 is a Linear Voltage Regulator developed by Texas Instruments. It belongs to the Power Management & Interface Circuit (PMIC) family, specifically the Voltage Regulators & Linear category. It is intended for applications in which a regulated output voltage is required. The device offers a wide variety of configurations, including both high and low range outputs.

The device has many features which makes it well-suited for use in both industrial and commercial applications. UCC383TDTR-3 is ideal for use in biomedical, automotive, and semiconductor applications which require a regulated power supply. It is also well-suited for distributed power systems which require regulation of both low and high range output voltages.

The UCC383TDTR-3 features a modulation frequency of up to 500KHz, allowing for high-speed switching over a wide range of input voltages. It also features a low quiescent current of 25µA and a low dropout voltage of 0.27V, ensuring a reliable and efficient regulator output. The device also has a wide temperature operating range of 0°C to 125°C and is protected against short circuits and excessive voltage and current.

The device is programmed to regulate the output voltage by applying a negative feedback signal to the error amplifier. This feedback signal is then used to compensate for variations in the input voltage, thereby maintaining a constant output voltage. This is accomplished by adjusting the current flowing through the output transistor. The output voltage is also adjustable by using a resistor divider.

The UCC383TDTR-3 also has the ability to sense load current and output current and can detect an overcurrent condition. It also has a low power standby mode, protecting the output when the load is removed, and a frequency compensation pin for easy tuning and stabilization.

The UCC383TDTR-3 is well-suited for a variety of applications, including distributed power supplies, battery-powered systems, and motor-drive applications. It is a reliable and efficient solution for applications requiring a high-speed, low quiescent current voltage regulator.
