Package Information
1A Low Dropout Regulator
DESCRIPTION
The EP1117 is a low dropout three-terminal
adjustable or fixed-voltage regulator with 1A
output current capability. The EP1117 is
available in an adjustable version, with output
ranging from 1.25V to 10.7V and fixed output
voltages of 1.8V, 2.5V and 3.3V. Dropout voltage
is guaranteed at a maximum of 1.3V at 1A.
On-chip thermal limiting provides protection
against any combination of overload that would
create excessive junction temperatures. The
EP1117 is available in the industry standard
3-pin the low profile surface mount SOT-223
power packages which can be used in
applications where space is limited.
