LNBK20PD-TR

Specialized Overview

The LNBK20PD-TR is a dedicated voltage regulator designed for Low Noise Block downconverter (LNB) supply and control applications. Manufactured by STMicroelectronics, this component features a parallel interface for configuration. It provides two independent output channels, each capable of delivering a maximum output current of 0.4 A. The primary regulated output operates within a range of 17.3 V to 18.7 V, with a nominal setting of 18 V. The device is housed in a 15-terminal FLANGE MOUNT package (R-PZFM-T15). It is rated for an operating junction temperature range from -40 °C to +125 °C.

Specialized Feature Summary

• Dual-channel power regulation supporting simultaneous LNB supply and control line requirements
• Parallel interface architecture enabling straightforward digital control and configuration
• Robust thermal design suitable for flange mount installation in demanding environments

Specialized Applications

• Satellite communication receiver systems requiring stable LNB power
• Control voltage generation for satellite antenna positioning mechanisms
• Telecommunications infrastructure equipment utilizing parallel-controlled regulators

Specialized Procurement Notes

Verify the specific suffix 'PD-TR' against the manufacturer's official documentation to confirm tape-and-reel packaging status and exact pinout compatibility. Ensure the procurement source provides valid traceability for automotive or industrial grade specifications if required by the system design. Cross-reference the RoHS compliance status and ECCN code EAR99 with current export regulations before finalizing orders.

Specialized Selection Notes

Select this component when a dual-output regulator with precise 18 V control is needed for satellite front-end modules. The 0.4 A per channel limit suits standard LNB loads. Verify that the system can accommodate the 15-pin flange mount form factor. Confirm that the parallel interface logic levels match the host controller's I/O capabilities. Consider thermal dissipation requirements given the 125 °C maximum junction temperature rating.

Specialized Part Context

This part belongs to STMicroelectronics' specialized power management portfolio, specifically targeting niche telecommunications and satellite applications. Unlike general-purpose PMICs, it focuses on integrated supply and control functions for LNBs. The product line emphasizes reliability in harsh electromagnetic environments typical of satellite ground stations.

Specialized Replacement Considerations

Direct replacements are not explicitly listed in public datasheets. Evaluate generic dual-output linear regulators with parallel interfaces only if pinouts and electrical characteristics (18 V nominal, 0.4 A) are identical. Verify package compatibility for R-PZFM-T15 flange mount designs.
