3.3V, or an adjustable output voltage which
may be set from 800mV to 5.5V. The LDO
delivers up to 300mA of output current, with a
foldback current limit of approximately
400mA. At 300mA load, dropout voltage
measures only 170mV for a 3.3V output.
Tight load and line regulation is achieved
over the full output current and supply range.
The high bandwidth control loop provides fast
transient response to reduce output voltage
deviation using low cost external ceramic
capacitors in the 1uF range.
