SE5117
Description
The
SE5117
is
an
efficient
linear
voltage regulator. It has extra low dropout voltage.
At light loads the typical dropout voltage is 5.5mV,
and at full load the typical dropout voltage is
650mV. The output voltage accuracy is better than
2%.
The SE5117 has low ground current, so it can
help prolong battery life. The SE5117 is specially
designed for hand-held, battery-powered devices.
Features
Typical 90mV dropout voltage at 150mA.
Guaranteed 1A output over the full operating
temperature range.
650mV typical dropout voltage at full load.
Extremely tight load and line regulation.
Low temperature coefficient.
Current and thermal limiting.
No-load stability.
Standard SOT-223 package.
