AO4801/MC4801

P-Channel 20-V (D-S) MOSFET

These miniature surface mount MOSFETs utilize a

high cell density trench process to provide low

r_DS(on)and to ensure minimal power loss and heat

dissipation. Typical applications are DC-DC

converters and power management in portable and

battery-powered products such as computers,

printers, PCMCIA cards, cellular and cordless

telephones.
