The UCC383TDKTTT-ADJ is a precision, high performance, adjustable linear voltage regulator that is included in the Part Number Database (PND) under Power Management Integrated Circuits (PMIC) – Voltage Regulators – Linear category. This model of regulator is designed to provide precise, precise and stable output voltage regulation while at the same time minimizing power dissipation.In general, linear voltage regulators work by actively controlling the voltage supply to the output terminals, utilizing the difference between the input and output voltages to control the amount of current into the output terminal, thereby regulating the output voltage. The working principles of Linear Voltage Regulators are relatively simple; they essentially consist of an operational amplifier (op-amp) and an output transistor, both connected to the positive input voltage and the negative reference voltage. The op-amp senses the voltage difference between the input and output, and adjusts its output voltage, causing the output transistor to increase or decrease its current regulating the output terminal.The UCC383TDKTTT-ADJ linear voltage regulator incorporates a unique design which includes an on-chip voltage reference regulator that is both precise and low-power. The on-chip voltage reference improves regulation accuracy, which is especially important when the regulator is used in power sensitive applications.The UCC383TDKTTT-ADJ linear voltage regulator also features an adjustable soft-start function that is used to prevent instability and increase regulator stability while reducing the time needed for the output voltage to reach its predetermined setting. The soft-start feature can also be used in applications that require a controlled ramp-up of the output voltage, thereby avoiding sudden current in-rush that may cause system instability during startup.The UCC383TDKTTT-ADJ is a highly efficient, precision linear voltage regulator, designed to meet the most demanding requirements of modern power systems. The wide operating voltage range (1.6V to 25V) makes the regulator suitable for use in a variety of applications, from low-voltage power supplies to high-end automotive applications. Thanks to its superior accuracy and low-power performance, the UCC383TDKTTT-ADJ is highly suitable for use in power management systems that require precise and stable output voltage regulation.
