The EP1117 is a low dropout three-terminal adjustable
regulator with 1A output current capability. In order to
obtain lower dropout voltage and faster transient
response, which is critical for low voltage applications,
the EP1117 has been optimized.
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. Current limit is
trimmed to ensure specified output current and controlled
short-circuit current. 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.
