About Linear Voltage Regulators
On Semiconductor Linear Voltage Regulators
Linear voltage regulators are electronic devices that regulate a voltage to a desired output. They work by adjusting the current, or quantity of electrical energy, to control the voltage output. They are typically used as part of a system to power electronics, including computers, laptops, phones, and other electronic devices. Linear voltage regulators can be either Step-down regulators, which reduce the input voltage to a lower output voltage, or Step-Up regulators, which increase the input voltage to a higher output voltage. Commonly used regulators feature LM7xx or LM1117 style parts, which are considered low dropout and can be used to regulate down or up to around 25V.
