What is compensated voltage regulator?
A compensated voltage regulator of the type used in programming non-volatile memory cells of a memory cell matrix that is divided into sectors. The voltage regulator includes a comparator that is connected to a supply voltage. Further, a compensation circuit is powered by the supply voltage.
How do I choose a LDO regulator?
To select a voltage regulator for your system, start by assuming a linear regulator can be used if the input voltage is higher than the output. Only if that wastes too much power, then use a buck switching regulator. If you need an output voltage higher than the input, then use a boost switching regulator.
How does LDO regulator work?
A low-dropout regulator’s (LDO) nature is to regulate a voltage by turning excess power into heat, making this integrated circuit a good fit for low-power or small VIN-to-VOUT differential applications.
What is line regulation in LDO?
Line regulation is a measure of the LDO’s ability to maintain the specified output voltage with varying input voltage.
Is a potentiometer a voltage regulator?
A voltage regulator is an electronic device connected to the output of a power supply to maintain the output voltage at its constant rated value. The variable resistor can be adjusted so that the voltage output through the system can remain constant. One method is the potentiometer.
Which regulator is more efficient?
5. Which type of regulator is considered more efficient? Explanation: The switching element dissipates negligible power in either on or off state. Therefore, the switching regulator is more efficient than the linear regulators.
Where is LDO regulator used?
The special feature of an LDO is its ability to have a very low voltage drop across it when providing a regulated output voltage. This allows the LDO to be used in power critical battery applications where the battery voltage (input voltage) is close to the required regulated output voltage.
How is regulator load regulation calculated?
Load regulation (percent) = 100 x (voltage no load — voltage full load) divided by voltage full load. Line regulation is another measure of voltage regulation.
