Description: General Description
The LM1084 is a series of low dropout voltage positive
regulators with a maximum dropout of 1.5V at 5A of load
current. It has the same pin-out as National Semiconductor’s
industry standard LM317.
The LM1084 is available in an adjustable version, which can
set the output voltage with only two external resistors. It is
also available in three fixed voltages: 3.3V, 5.0V and 12.0V.
The fixed versions intergrate the adjust resistors.
The LM1084 circuit includes a zener trimmed bandgap reference,
current limiting and thermal shutdown.
The LM1084 series is available in TO-220 and TO-263 packages.
Refer to the LM1085 for the 3A version, and the
LM1086 for the 1.5A version.

Description: Opentracker is a lightweight BitTorrent tracker which uses minimal resources (it runs fine on your WLAN router). The software does not store any data or log any IP-addresses and is more stable and efficient than most other tracker software.
The Pirate Bay had been testing Opentracker for a few weeks before they completely abandoned Hypercube. They have now switched to the new software on all their trackers, 16 in total.
We asked TiAMO from The Pirate Bay why they decided to switch to Opentracker, he told us: “Well it’s faster than hypercube and uses less resources. Also it supports UDP tracking which hypercube did not.”
