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.
