LD6918 - Leadtrend

LD6918 Low-Noise CMOS Dual LDO Regulators

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 ±1% and output current is up to 300mA. As well, the LD6918 can be stable with a 1μF low ESR ceramic output capacitor which reduces the board space and cost. The LD69.
