Low Dropout Voltage Regulators

Low dropout voltage regulators are types of linear regulators that provide an inexpensive way of regulating output voltage with few external components. Linear regulators are used to maintain a steady voltage in electronic devices. Low dropout voltage regulators can regulate output voltage even when it's very close to the supply voltage. They have low noise and good ripple rejection making them crucial to maintaining a stable power supply in any power-management system.


What are low dropout voltage regulators used for?


Low dropout voltage regulators help to maintain system voltage independent of battery. This makes them useful for portable applications, as well as for equipment that needs a stable voltage while minimising the supply. You're likely to find low dropout voltage regulators in devices such as smoke detectors or alarm systems.


Choosing the right low dropout voltage regulator


There are various factors to consider when choosing the right regulator. These include required output voltage, maximum load current, minimum dropout voltage and the type and range of input voltage. Low dropout voltage regulators are the right choice if a more precise output voltage is necessary and there is a low power dissipation.
