LD6911 - Leadtrend

LD6911 Ultra-Fast CMOS LDO Regulator

The LD6911 is a micropower linear regulator, featuring low-noise, low-dropout and high ripple rejection ratio. The precision of feedback reference voltage is within ±2% and output current is up to 300mA. As well, the LD6911 can be stable with a 1μF output capacitor, which will reduce the board space and cost. The LD6911 is available in a space saving SOT23-5.
