LD6909 - Leadtrend

LD6909 300mA CMOS LDO Regulator

The LD6909 is a micropower linear regulator, featuring low-noise, low-dropout and high ripple rejection ration. The precision of feedback reference voltage is within ±2% and output current is up to 300mA. As well, the LD6909 can be stable with an output capacitor of 1µF which reduces the board space and cost. The LD6909 is available in a space saving SOT23-5.
