The NCP1117DT50 is a Linear Integrated Circuit (IC) voltage regulator which is part of the family of voltage regulators produced by ON Semiconductor. This voltage regulator is an adjustable 3-terminal negative voltage regulator (otherwise known as a buck converter) which is designed to supply an adjustable output voltage from an input voltage of up to 35V DC. It has been designed for use in applications such as cameras, phones, computers and other electronic equipment, and is available in a surface mount 8-pin Dual Inline Package (DIP) configuration.

The NCP1117DT50 operates using Voltage Regulator Circuit (VRC) technology which provides a regulated output voltage that is independent of load current, line voltage and temperature variations. This ensures that the output voltage remains constant over a wide range of operating conditions. The device also uses an internal voltage reference which allows the output voltage to be set between 0V and the input voltage minus a tolerance of 1.5V. The maximum output current of the device is rated at 1.5A.

The NCP1117DT50 works by essentially increasing or decreasing the primary winding on a transformer to regulate the output voltage. It does this by controlling the amount of current that is allowed to pass through the primary winding. The current flowing through the transformer is regulated by a power transistor which acts as a switch. When the transistor is turned on, current flows through the primary winding, building up a magnetic field. When the transistor is turned off, the magnetic field collapses and causes the voltage in the secondary winding to be stepped up.

The amount of current flowing through the power transistor is determined by the voltage applied to the reference and control settings. When the voltage at the reference and control settings is increased, the current flowing through the power transistor increases, resulting in an increased output voltage. Similarly, when the voltage of the reference and control settings is decreased, the current flowing through the power transistor decreases, resulting in a decreased output voltage.

In summary, the NCP1117DT50 is an adjustable 3-terminal negative regulator IC which provides a regulated output voltage of up to 35V DC. It operates using Voltage Regulator Circuit (VRC) technology which ensures a constant output voltage regardless of line voltage, load current and temperature variations. The device features an internal voltage reference which allows the output voltage to be set between 0V and the input voltage minus a tolerance of 1.5V, and has a maximum output current rating of 1.5A.
