Components used to adjustable voltage regulator:

MJE13003 Transistor

High voltage fast-switching NPN power transistor. The device is manufactured using high-voltage multi-epitaxial planar technology for high switching speeds and high-voltage capability. It uses a cellular emitter structure with planar edge termination to enhance switching speeds while maintaining the wide RBSOA.

Structure of MJE13003 Transistor

This is an NPN transistor. Features: High voltage capability, Low spread of dynamic parameters, Very high switching speed and Applications: Electronic ballast for fluorescent lighting (CFL), SMPS for battery charger

These devices are designed for high−voltage, high−speed power switching inductive circuits where fall time is critical. They are particularly suited for 115 and 220 V SWITCHMODE applications such as Switching Regulators, Inverters, Motor Controls, Solenoid/Relay drivers and Deflection circuits.

10k Variable Resistor

A variable resistor typically has three terminals: two fixed terminals at the ends of the resistive track and one movable terminal (the wiper). Depending on how the terminals are connected to a circuit, a variable resistor can function as a rheostat or a potentiometer.A resistor of which the ohmic resistance value can be adjusted. Either mechanically (potentiometer, rheostat) or electronically (digital potentiometer). A variable resistor is a resistor for which the electric resistance value can be adjusted. A variable resistor is in essence an electro-mechanical transducer and normally works by sliding a contact (wiper) over a resistive element. When a variable Resistor is used as a potential divider by using 3 terminals it is called a potentiometer.
