Product details
Overview
ARG81300SESWTR from Allegro MicroSystems is a single LNB supply and control voltage regulator for satellite receiver and set-top-box applications. The device generates controlled 13V or 18V LNB supply outputs from a 9V to 16V input and includes tone and interface features required for LNB control systems.
As part of the ARG81300 product family, ARG81300SESWTR combines a boost regulator, LNB supply voltage selection, 22kHz tone generation and detection support, I2C-compatible control, output current limiting, diagnostic reporting, and a compact 3mm x 3mm QFN package. For engineers reviewing the ARG81300SESWTR datasheet, ARG81300SESWTR pinout, ARG81300SESWTR application, or ARG81300SESWTR equivalent, this device is widely used in satellite receivers, set-top boxes, LNB power supplies, antenna control modules, digital TV equipment, and compact RF distribution systems.
Technical Context
In satellite receiver systems, ARG81300SESWTR operates as an LNB voltage regulator that boosts a local 9V to 16V supply to the 13V or 18V levels required by LNB polarization control.
The device supports 22kHz tone generation and tone-detection functions used in satellite control signaling. The I2C-compatible interface allows system firmware to configure output and monitor fault or diagnostic conditions.
ARG81300SESWTR is commonly used when a compact QFN regulator must provide controlled LNB supply voltage, current limiting, tone signaling, and digital control in set-top-box or satellite front-end hardware.

Pinout & Package
The ARG81300SESWTR pinout includes input supply, boost switch/inductor pins, LNB output, tone-related pins, I2C interface pins, enable/control functions, fault/status pins, and exposed-pad ground.
For PCB design, the boost current loop should be compact, LNB output filtering should follow the tone and load-current requirements, and I2C/control traces should be routed away from the switching node.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A8293SESTR-T | Allegro LNB supply and control voltage regulator with different current and package details. | Used in similar satellite receiver LNB supply applications. | Compare output current, interface features, package, and tone behavior. |
| LNBH25LSPQR | STMicroelectronics LNB supply and control IC with different interface and protection behavior. | Used in satellite set-top-box LNB power systems. | Compare current limit, package, I2C behavior, and tone functions. |
Compared with A8293SESTR-T, ARG81300SESWTR should be selected when its compact 3mm x 3mm QFN package and current/tone feature set match the receiver design. ARG81300SESWTR vs LNBH25LSPQR selection depends on LNB output current, interface, protection, and package requirements.
Quality
ARG81300SESWTR should be sourced as original Allegro MicroSystems components through traceable supply channels. Quality checks may include package inspection, top-mark validation, solderability testing, rail output verification, protection behavior review, and thermal inspection.
Production validation should include startup behavior, output accuracy, load transients, thermal performance, protection response, and layout-sensitive switching behavior where applicable.
