PT4404 Datasheet (PowTech) - Low Dropout Adjustable 350mA Current Regulator

PT4404, Low Dropout Adjustable 350mA Current Regulator

PT4404 is a low dropout current regulator with an adjustable constant sink current sink of up to 350mA.

The dropout voltage at 350mA is typically 110mVwith the quiescent current of only 100μA.

The enable pin is used to shutdown the chip or control the LED brightness with a PWM signal.
