LNBH25LSPQR ST Power Management IC | 24-VFQFN Exposed Pad | 0.8A, 15V

Product Overview

The LNBH25LSPQR is a monolithic voltage regulator and interface IC designed for satellite LNB (Low Noise Block) power supply and control. Manufactured by STMicroelectronics, this device integrates a step-up DC-DC converter, a linear regulator, and a DiSEqC (Digital Satellite Equipment Control) interface in a compact 24-VFQFN exposed pad package. It provides a regulated output voltage of 13V or 18V (selectable) with a maximum output current of 0.8A, making it ideal for powering LNB modules in satellite TV receivers, set-top boxes, and professional satellite communication systems.
