Product details
Overview
LNBP13SP-TR from STMicroelectronics is a monolithic linear voltage regulator in PowerSO-10 package, designed to supply and control LNB downconverters via coaxial cable in dual-port satellite receivers. It delivers 13 V (typ.) or 14 V (typ.) output at up to 650 mA, features factory-trimmed 22 kHz tone generation (±2 kHz tolerance), dynamic overload protection with 4.7 µF CEXT timing, and backward current limiting to 3 mA in stand-by mode. Used in analog/digital satellite set-top boxes requiring remote LNB powering and DiSEqC™ encoding.
For engineers reviewing the LNBP13SP-TR datasheet, LNBP13SP-TR pinout, LNBP13SP-TR application, or LNBP13SP-TR equivalent, key selection criteria include dual-voltage output logic control (VSEL/LLC), integrated tone oscillator start-up time for burst coding, thermal shutdown at 150 °C, bypass switch functionality for slave operation, and line-length compensation capability.
Technical Context
The LNBP13SP-TR implements a dual-input linear regulator architecture with automatic VCC1/VCC2 selection: VCC1 (15–25 V) powers 13/14 V outputs, while VCC2 (22–25 V) supports higher-output configurations. Its internal 22 kHz oscillator enables DiSEqC™ burst signaling via ENT pin control, with fast start-up facilitating precise tone gating.
Overload protection operates dynamically using an external capacitor on CEXT to set off-time (1100 ms typ. with 4.7 µF); OLF provides open-collector diagnostic flagging. The device integrates back-current protection (0.2–3 mA max) when EN is low, and supports master/slave topology via MI-to-LNBA bypass switch (0.35–0.6 V drop at 300 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 13 V (typ.) or 14 V (typ.) selectable via VSEL/LLC logic inputs - enables standard LNB biasing and coaxial voltage-drop compensation. |
| Max Output Current | 650 mA (typ.) - sufficient to drive high-capacitance LNB loads without external boost circuitry. |
| Tone Frequency | 22 kHz ±2 kHz (factory trimmed) - meets DiSEqC™ 1.x specification without calibration components. |
| Dynamic Overload Off-Time | 1100 ms (typ., CEXT = 4.7 µF) - limits power dissipation during sustained short-circuit events. |
| Backward Current Limit | 3 mA (max, EN = LOW) - prevents reverse feed from shared coaxial lines in multi-receiver installations. |
| Thermal Shutdown | 150 °C junction temperature - protects die integrity under sustained overload or poor heatsinking. |
| Supply Input Range | VCC1: 15–25 V; VCC2: 22–25 V - allows optimized efficiency by selecting lowest viable input rail per output voltage. |
Pinout & Package
LNBP13SP-TR is housed in a surface-mount PowerSO-10 package (9.4–9.6 mm × 13.8–14.4 mm × 3.7 mm height), featuring exposed die pad for thermal conduction and ECOPACK® lead-free finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC1) | Primary supply input | 15–25 V rail used when 13/14 V output selected; lower voltage minimizes dissipation. |
| 2 (VCC2) | Secondary supply input | 22–25 V rail automatically engaged for higher output voltages; supports single-rail 23 V operation. |
| 3 (LNBA) | Main LNB output port | Delivers regulated 13/14 V to antenna port A; routed from MI pin in stand-by mode via internal bypass switch. |
| 4 (VSEL) | Voltage selection control | Logic input determining base output: LOW = 13 V, HIGH = 18 V - LLC modifies this by +1 V. |
| 5 (EN) | Enable/disable control | Active-HIGH logic enabling both outputs; LOW disables outputs and activates <3 mA backward current limit. |
| 7 (OSEL) | Port selection control | Not connected (NA) in PowerSO-10 variant - LNBB output disabled; only LNBA active. |
| 8 (CEXT) | Overload timing node | Connects external capacitor (e.g., 4.7 µF) to set dynamic protection cycle duration (toff ≈ 1100 ms). |
| 9 (ENT) | Tone enable input | Active-HIGH control of internal 22 kHz oscillator; enables DiSEqC™ tone modulation without external crystal. |
| 10 (GND) | Power and signal reference | Internally bonded to die frame; requires low-impedance PCB ground plane for thermal and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply input selection | Automatically switches between VCC1 and VCC2 based on VSEL/LLC state - reduces thermal stress by ~30% vs fixed-rail designs. |
| Factory-trimmed 22 kHz oscillator | ±2 kHz accuracy at 22 kHz - eliminates need for external tuning components and board-level calibration. |
| Dynamic overload protection | Self-resetting cycle (toff/ton ≈ 15:1) with user-defined timing - sustains operation during intermittent shorts without latch-up. |
| Master-slave bypass switch | MI-to-LNBA electronic switch (0.35–0.6 V drop) activated when EN = LOW - enables shared coaxial infrastructure in multi-receiver systems. |
| Line-length compensation | +1 V output offset via LLC pin - corrects coaxial voltage drop up to ~30 m RG-6 cable at 500 mA load. |
Applications
| Satellite Set-Top Box (Dual-Port) | Single-Dish Multi-Receiver System |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LNB supply and control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LNBP12SP-TR | Fixed 13 V output (no LLC compensation); same PowerSO-10 package and pinout. | Lacks line-length compensation - unsuitable for long coax runs (>15 m) at full load. | Select when system uses short cables and cost sensitivity outweighs voltage-drop margin. |
| LNBP14SP-TR | Supports 14 V/19 V outputs (VSEL+LLC HIGH); identical protection and tone features. | Enables higher-voltage LNBs requiring 19 V bias - not compatible with standard 13/18 V LNBs without firmware update. | Select for new designs targeting extended LNB compatibility or future-proofing against evolving LNB specs. |
Compared with LNBP12SP-TR, LNBP13SP-TR adds 1 V line-length compensation for longer coaxial drops; compared with LNBP14SP-TR, it avoids overvoltage risk on legacy 13/18 V LNBs while retaining full DiSEqC™ functionality and thermal robustness.

FAQ
What is the purpose of the CEXT pin on LNBP13SP-TR?
The CEXT pin connects an external capacitor (typically 4.7 µF) to configure the dynamic overload protection timing. When an LNB short occurs, the device cycles between OFF time (toff ≈ 1100 ms) and ON time (ton ≈ toff/15), reducing average power dissipation while maintaining self-recovery capability. This avoids thermal shutdown lockout and supports hot-plug LNB insertion.
Can LNBP13SP-TR drive both LNBA and LNBB outputs simultaneously?
No. In the PowerSO-10 package (LNBP13SP-TR), the OSEL pin is not bonded out, and LNBB functionality is disabled. Only LNBA is active. Dual-output operation requires the PowerSO-20 variant (e.g., LNBP20PD-TR). This package limitation is explicitly documented in Table 1's "vs SALES TYPE" column for LNBP13SP-TR.
How does the LLC pin affect output voltage?
The LLC pin adds +1 V (typ.) to the base voltage set by VSEL: when VSEL = LOW (13 V), LLC = HIGH yields 14 V; when VSEL = HIGH (18 V), LLC = HIGH yields 19 V. This compensates for coaxial cable voltage drop - for example, a 14 V output maintains ≥13 V at the LNB after 25 m of RG-6 cable at 500 mA load.
Is external filtering required on VCC1/VCC2 inputs?
Yes. The datasheet specifies CI = 0.22 µF ceramic capacitor on each supply input (VCC1 and VCC2) for stability and transient suppression. Omitting these capacitors risks oscillation under load transients and may trigger premature thermal shutdown due to localized heating at the input stage.
