DC/DC Conversion

From Microchip Technology, Inc.
 

 
Closed loop control with linear regulators. Often the voltage source is "incompatible" with the load. A buffer needs to be placed between the source and load to regulate or control the voltage and/or current. Linear regulators provide closed loop control to "regulate" the voltage at the load. A basic linear regulator has three main components: an operational amplifier, a voltage reference and a pass transistor. The main purpose of a linear regulator is to produce a constant, accurate output voltage at a lower magnitude than the input voltage. Beyond the basics, linear regulators often offer additional features: over-current protection, thermal protection and reversed polarity protection to name a few. Microchip offers a line of CMOS, low dropout linear regulators. A low dropout regulator is a type of linear regulator designed to minimize the saturation voltage of the output transistor and to minimize the gate drive requirements. LDOs can operate with a very small input to output differential.
