LNBH25PQR ST Power Management IC | 24-QFN (4x4) | 0.9A, 15V

Product Overview

The LNBH25PQR from STMicroelectronics is a highly integrated power management IC designed for satellite LNB (Low Noise Block) supply and control. It provides a regulated output voltage of 13V or 18V (selectable) with a maximum output current of 0.9A, supporting both DiSEqC 2.x and 22 kHz tone signaling. Packaged in a compact 24-QFN (4x4 mm), it offers high efficiency and low power dissipation, making it ideal for space-constrained applications.
