BECE MODULE 6

• Integrated Circuit- versatile and relatively inexpensive and are available with features such as a programmable output, current voltage boosting, internal short circuit current limiting, thermal shutdown, and floating operation for high voltage application
• Voltage Regulator- comprises a class of widely employed ICs.Regulator IC units contains the circuitry for reference source, comparator amplifier, control device, and overload protection all in a single IC
• IC Voltage Regulator Types

  Fixed output voltage regulators positive and or negative output voltage

  Adjustable output voltage regulators positive or negative output voltage,

  Switching regulators - more efficient than the linear regulators

  Special regulators- Employed as control circuits in pulse width modulation, push-pull bridges, and series type switch mode supplies
