6/6/2008
300mA, Low Noise, Ultra-Fast CMOS LDO Regulator with
Soft Start Function
REV: 00
General Description
The LD6915 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 LD6915 can be
stable with an output capacitor of 1μF which reduces the
board space and cost.
The LD6915 is available in a space saving SOT23-5,
SC70-5 and SC82-4 package.

Chip Enable, High=Enable, Low=Disable
This pin combines noise reduction and soft start function. Connect a
capacitor to GND to adjust soft start time. For soft start operation
Css>1nF is recommended. Open this pin to disable soft start function.
