TRACOPOWER Switching Regulator Through Hole 3.3V DC Output Voltage 2A Output Current TSR 2-2433

TRACOPOWER TSR 2-2433 switching regulator is a high-performance, compact step-down power supply designed for electronic component applications requiring a stable 3.3V DC output voltage at a current capacity of 2 amperes. It features a through-hole mount and SIP package type, enabling straightforward integration into printed circuit boards for industrial, laboratory, manufacturing, and electronic system development use cases.

This switching regulator operates efficiently within an input voltage range from 4.75V up to a maximum of 36V DC, boasting an efficiency rating of 91%, significantly reducing the need for additional heat dissipation components such as heat sinks. The design incorporates integral short circuit protection, delivering robust reliability for demanding applications.

Key performance parameters include load regulation of 1%, line regulation of 0.5%, and output ripple and noise limited to 50mV peak-to-peak. It maintains stable operation within a broad ambient temperature range from -40°C to +85°C, suitable for harsh environments. The device complies with multiple safety and quality standards including IEC/EN 60950-1, UL 94 V-0, UL 60950-1, and MIL-STD-810F, ensuring dependable performance.

Physically, the module measures 14mm in length, 10.1mm in depth, and 7.5mm in width, with a lightweight 2.6g body. Its mean time between failures (MTBF) is rated at over 13 million hours, reflecting exceptional reliability. The TSR 2-2433 series stands as a modern replacement for older LMxx series linear regulators, offering improved output accuracy and lower standby currents.

Ultra-compact SIP package suitable for efficient PCB integration. Supports input voltages from 4.75V to 36V DC. High efficiency of up to 91%, reducing heat dissipation needs. Includes integral short circuit protection for enhanced reliability.

Operates reliably between -40°C and 85°C ambient temperature. Delivers low ripple and noise output of 50mV peak-to-peak. Complies with IEC/EN 60950-1 and UL 94 V-0 safety standards. Designed as a drop-in upgrade for legacy LMxx linear regulators.
