A linear regulator is a type of voltage regulator IC that acts as a variable resistor in response to changes in input voltage or output current in order to maintain output voltage regulation. There are two types of linear regulators: series regulators and shunt reg...
Linear regulator operating principle Internal configuration of a linear regulator ・What is an LDO (low dropout voltage regulator)? An LDO regulator is a linear regulator that can operate at a very low potential difference between the input and output voltage. A linear regulator is a type of ...
In a linear regulator Input power = Input voltage × Load current = 5.0V × 0.1A = 0.5W Output power = Output voltage × Load current = 2.5V × 0.1A = 0.25W Since efficiency = Output power ÷ Input power, the efficiency of a linear regulator is 50%. A switching regulator, however,...
Linear regulators adjust the internal driver's on resistance to 30 ohms.RD = 30 ohms and RL = 20 ohms will form divider resistors to output 2 V from 5 V.Therefore, the output voltage of linear regulator, Vout, is expressed as the voltage division of input voltage, Vin, by the ratio ...
Although controllability and observability are distinct properties, one of the fundamental-and most attractive-results of our field is the fact that (A, B) is controllable if and only if f (AT,BT) is observable. This duality provides a deep linkage between the linear-quadratic regulator (LQR)...
What is a voltage regulator? A power supply IC that produces a constant output voltage in response to the input voltage, output current, and load resistance is called a voltage regulator. This page explains linear voltage regulators that do not perform switching operations. ...
LDO is a low dropout regulator, a kind of low dropout linear regulator. Traditional linear regulators, such as the 78XX series of chips require the input voltage to be at least 2V ~ 3V higher than the output voltage, otherwise, it will not work properly. But in some cases, such conditi...
Why is a DC-DC converter needed?A DC-DC converter is needed to convert and stabilize the voltage. Power Supply IC TypesThere are two main types of power supply ICs: linear regulators and switching regulators. Linear RegulatorAs its name suggests, a linear regulator is one where a linear com...
LQR is a type of optimal control based on state-space representation. In this video, we introduce this topic at a very high level so that you walk away with an understanding of the control problem and can build on this understanding when you are studying the math behind it. This video wi...
Electromagnetic Compatibility (EMC) is the ability of a device or system to operate satisfactorily in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the ...
