LNBH25LSPQR ST Satellite LNB Supply | 24-QFN(4x4) | 0.8A, I2C

Product Overview

The LNBH25LSPQR is a monolithic voltage regulator and interface IC designed for satellite LNB (Low Noise Block) supply and control. Manufactured by STMicroelectronics, this device integrates a step-up DC-DC converter, a linear regulator, and I2C interface for DiSEqC (Digital Satellite Equipment Control) encoding. It provides a regulated output voltage of 13V or 18V (selectable) with a maximum output current of 0.8A, suitable for powering LNB modules in satellite TV receivers and set-top boxes. The device is housed in a compact 24-QFN (4x4 mm) package, enabling space-efficient designs.
