Low-Dropout (LDO) linear regulators are a simple solution for using an integrated circuit to regulate a higher voltage to a lower voltage without the use of an inductor. Power management is vital in a world driven by battery-powered small devices that require efficient power consumption and precision. LDO regulators span a wide spectrum of specialized uses and can be widely implemented in today’s electronics due to their simplicity and low cost.
