KILAR KV1084 5A linear regulator : weekend die-shot

Remember good old times when you could feed CPU from single linear regulator? KILAR KV1084 came from this time.

Comparing to LM2940L or LM1117 there are more bonding pads per signal and obviously larger output transistors. Chip was soldered on copper heat spreader to help dissipate 10W+.

Die size 3075x3026 ┬Ám.
