LD6918
LD6918-300mA, Low-Noise CMOS Dual LDO Regulators

General Description

The LD6918 is a dual micro power linear regulator, featuring low quiescent current, low-noise, low-dropout and high ripple rejection ration. The precision of feedback reference voltage is within ??% and output current is up to 300mA. As well, the LD6918 can be stable with a 1?�F low ESR ceramic output capacitor which reduces the board space and cost.

The LD6918 is available in SOT23-6; DFN-8L 3 x 3; DFN-8L 2 x 2 and DFN-6L 1.6 x 1.6 packages.
