General Description
The EM5201B is a small, ultra-low RON, single
channel load switch with controlled turn on. The device
contains an N-channel MOSFET that can operate over
an input voltage range of 0.8V to 5V and can support a
maximum continuous current of 4.5A.
The combination of ultra-low RON and high
current capability of the device makes it ideal for driving
processor rails with very tight voltage dropout
tolerances.
The EM5201B is available in a small, space-saving
SOT23-6 with integrated thermal pad allowing for high
power dissipation.
