SE9135 Datasheet, PDF (1/4 Pages) Seaward Electronics Inc. – 350mA Advanced Current Regulator

Description
The SE9135 is a low dropout current regulator
rated for 350mA constant sink current. The constant
sink current will ensure that the same amount of
power is applied to the power LED and
consequently maintain the uniform brightness
throughout the possible voltage variations from the
power source. The IC also features low quiescent
current and is typically at 212uA. This will minimize
the power consumption from the IC itself.
The IC has EN function built-in for applications
where EN function or Dim function is needed.
Please contact us directly if EN function is required.
SE9135 is presently available in low profile
SOT-89-3L and TO-252 packages.
