300mA CMOS LDO Regulator
LD6909
5/1/2006
REV:00
General Description
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 or
SC70-6 package.
