View All Products/Datasheets

A linear regulator (LDO regulator, low dropout voltage regulator) is a type of power supply IC that can output a steady voltage from an input voltage and is used in a variety of electronic devices.
ABLIC's linear regulators (LDO regulators) feature ultra-low current consumption, high-withstand voltage, a wide operation voltage range, ultra-small/thin packages, and a high ripple rejection ratio. They contribute to the low power, stable operation, and high reliability of power supply circuits. Furthermore, to meet customers' needs, ABLIC offers a wide variety of product lines including a soft-start circuit, an inrush current limit circuit, an open-loop protection function, a discharge shunt function, an output voltage external setting, and a supply voltage divided output.
With these features, ABLIC's linear regulators are used in a wide range of applications, including mobile devices, home electronics, housing equipment, and industrial equipment.。

*Our voltage regulator (LDO regulator) product line has been renamed to “linear regulator” (LDO regulator). This is a change in name only, which does not affect product specifications or performance. Please note that the previous name may still be used in some of our data sheets and other publications.
