Product details

Satellite LNB supply regulator with dual output rails

It accepts a 4.5V to 20V input rail and delivers a regulated output that switches between 13.4V and 18.6V — the two standard supply voltages for LNB polarisation control.

The single output switches between 13.4V and 18.6V, which correspond to the vertical and horizontal polarisation supply levels required by satellite LNB front-ends.

Frequently asked questions

Is TPS65233-1RTET obsolete or end-of-life?

No.

What is the difference between TPS65233-1RTET and TPS65233-1RTER?

The suffix difference indicates packaging and reel quantity variants within the same TPS65233 base product family. Both share the same die and electrical specifications — the -1RTET and -1RTER suffixes denote different tape-and-reel configurations. Confirm the specific reel quantity and tape width with your distributor when ordering.
