Linear Regulators (LDO Regulators)

ABLIC’s linear regulators (LDO regulators) feature the low current consumption, high-withstand voltage, wide operating voltage range, super-small packages, and high ripple rejection ratio. Our LDO regulators contribute to the low power, stable operation and high reliability of power supply circuits. ABLIC offers a wide variety of product lines including a soft start circuit, a inrush current limit circuit, discharge shunt function, output voltage external setting, output capacitor-less, a supply voltage divided output to meet customers needs.

*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.
