LNBR voltage regulator IC for satellite TV receivers

The device is a single-channel LNBR IC that offers industry-leading internal protection and robustness, an integrated boost MOSFET, current sensing, and compensation which simplifies the  design and minimises component count and PCB size. The A8303 has a low supply current to save energy, incorporates a high level of diagnostics, and features a resistor-programmed output current limit to minimise the boost inductor/diode size and hence costs.

The A8303SESTR-T is available in a 4 × 4 TQFN/MLP-20 package.
