LNBH23TPPR

Special Purpose Regulators Overview

The LNBH23TPPR is a monolithic integrated circuit designed for Low-Noise Block downconverter (LNB) supply and control applications. It integrates a step-up converter, voltage regulator, and an I²C interface to manage power delivery in satellite reception systems. The device operates within a supply voltage range of 8V to 15V and supports a junction temperature range from 0°C to 85°C. It is housed in a 24-pin PowerBSOP package with a width of 7.50mm, providing a compact solution for signal conditioning and power management in analog and digital satellite receivers.

Special Purpose Regulators Feature Summary

• Integrates a step-up converter and voltage regulator for efficient power management
• Features an I²C interface for precise control and monitoring
• Designed specifically for LNB supply and control functions

Special Purpose Regulators Applications

• Satellite television (SatTV) receivers
• Set-top boxes (STB)
• Analog and digital satellite receiver systems

Special Purpose Regulators Procurement Notes

Verify the component status as End-of-Life (EOL) before procurement planning. Confirm tariff applicability for shipments to the United States, as costs may be calculated separately. Ensure compatibility with existing PCB footprints and design requirements given the discontinued manufacturing status.

Special Purpose Regulators Selection Notes

Select this component for designs requiring integrated LNB power control via I²C. Verify that the 24-PowerBSOP package fits the board layout constraints. Confirm that the 8V–15V input range matches the system power supply specifications. Consider alternative components if long-term availability is critical due to EOL status.

Special Purpose Regulators Part Context

The LNBH23 series belongs to STMicroelectronics' portfolio of special purpose regulators tailored for satellite communication equipment. These ICs consolidate multiple power management functions into a single chip, reducing component count and board space. The LNBH23TPPR variant specifically utilizes the PowerBSOP package for thermal and spatial efficiency in consumer electronics.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, engineers should consult official replacement guides or contact STMicroelectronics directly for qualified alternatives.
