I have a pulse that is approx 5ma at 3.3V
This needs to drive a device that needs 50-100ma at 3.3V
I can supply 3.3V or 5A for operational voltage.
any idea what IC I could use for this ?
I know I can build a current gain circuit from a npn transistor, but I am hoping that a low power current amp is available as a standalone IC.
EDIT: Just got pointers to use a MOSFET for gain.
My requirements are very similar to this thread.

Boncuk suggested this
V(BR)DSS=30V, RDS(ON)=0.08Ω, ID=3.5A, VGS(th)=0.7V, package SOT23
ZETEX ZXMN3B14F.
