The TSRN 1-2433 is a 1-output Step-down Switching Regulator, suitable for positive or negative output circuits. It is a drop-in replacement for inefficient 78xx linear regulators. A high efficiency allows full load operation up to +70°C (+85°C with derating) ambient temperature without the need of any heat-sink or forced air cooling. It has better output accuracy (±2%), lower standby current of 2mA and no requirement of external capacitors.
