I have seen a number of circuits that use a small (~0.1 Ohm) resistor on th=
e
outputs to parallel them and handle increased current.  Why not use a
LM123/223/323.  They can supply 3A@5V but they come in a TO-3 or TO-220
case. =20

Subject: [EE] Regulators in parallel

Hey all,

I'm having trouble finding LDO linear regulators that can supply > 1 A at 5
V, so I'm thinking of stacking a few 250 mA or 500 mA regulators in
parallel. I want to draw around 1.1 A or so.

Is this a good idea? Is there anything I should watch out for?
