Re: Samsung LN-S3251D
LDO is a specific type of linear regulator: Low Dropout. Which means that if it's a 5V regulator, you can give it 6V and it still works (or less depending upon several factors), whereas a non LDO linear regulator is going to need at least 6.5V-7V to operate.
Linear Regulators are regulators that generate the required voltage by dissipating the excess voltage as heat. A switching regulator does not do that, but "switches" the current on and off at a high frequency. After that... well, that's beyond this post...
It may be connected to the heatsink, it may not, all depends upon how much current it's expected to deliver. It doesn't have to be on the PSU either...
I assume you don't have a scope? So finding it's going to be difficult.
