voltage transients. By controlling the gate of an external n Adjustable Output Clamp Voltage N-channel MOSFET, the LTC4366 regulates the output n Controls N-Channel MOSFET during an overvoltage transient. The load may remain n Adjustable Protection Timer operational while the overvoltage is dropped across the n Internal 9-Second Cool-Down Timer MOSFET. Placing a resistor in the return line isolates the n Shutdown IQ < 14µA LTC4366 and allows it to float up with the supply; therefore, n 8-Lead TSOT and 3mm × 2mm DFN Packages the upper limit on the output voltage depends only on the availability of high valued resistors and MOSFET ratings.
