Performance Enhancement Techniques for Three-Terminal Regulators

Focus:

Adding some additional circuitry to a three-terminal voltage regulator can extend its performance by increasing output current capability, limiting power dissipation for improved efficiency, extending operation to higher voltages, increasing stability over time and temperature, and permitting operation off of different ac line voltages.

What you’ll learn:

• How to increase the current capability of three-terminal voltage regulators
• How to limit the power dissipation of a three-terminal regulator for improved efficiency and thermal management
• How to extend operation of a three-terminal regulator to high voltages while protecting against output shorts to ground

Notes:

Also: How to increase the stability of a three-terminal voltage regulator's output over time and temperature and How to power a three-terminal voltage regulator off of 110 Vac or 220 Vac without switching transformer windings and with no increase in regulator power dissipation at the higher line voltage.
