TRACOPOWER Switching Regulator Through Hole 2.5 V dc Output Voltage 1 A Output Current TSRN 1-2425

TRACOPOWER TSRN 1-2425 Switching Regulator is a through hole, 1 A step-down switching power supply module specifically designed for high efficiency and reliable voltage conversion. This SIP package regulator supports output voltages of ±2.5 V DC, suitable for both positive and negative output circuits. It features a wide input voltage range up to 42 V DC and an efficiency of up to 95%, allowing full load operation without requiring additional heatsinks or forced air-cooling, making it ideal for energy sensitive and compact applications.

The device includes built-in filter capacitors and protection against over-temperature and short circuits, ensuring robust performance in demanding industrial, electronic, and laboratory settings. Its low standby current (only 1 mA for 5.0 V DC output models) reduces energy consumption. Furthermore, it exhibits excellent line regulation at ±0.2% and load regulation at ±0.4%, ensuring stable voltage supply under variable loads and input conditions.

The TSRN 1-2425 unit is commonly used in industrial power supplies, embedded systems, telecommunications equipment, instrumentation, and other electronics requiring precise voltage regulation. Its operating temperature range from -40°C to 85°C enables deployment in a wide variety of environmental conditions.

The package features a SIP form factor with through-hole mounting in a TO-220 compatible footprint, facilitating easy integration into printed circuit boards. The pin compatibility with LMxx linear regulators allows straightforward replacement or upgrade without PCB redesign. Notably, for input voltages exceeding 36 V DC, the use of a 22 μF / 50 V input capacitor is recommended for optimal performance.

Supports wide input voltage range up to 42 V DC for versatile application. No heatsink required due to high efficiency up to 95%. Includes over-temperature and short circuit protection for safety. Low standby current reduces energy consumption in standby mode.

Excellent line and load regulation ensures stable output voltages. Operates over a broad temperature range from -40°C to 85°C. Pin compatible with LMxx linear regulators for easy upgrades. SIP package fits TO-220 footprint for standard mounting.
