TRACOPOWER Switching Regulator, PCB Mount, 5V dc Output Voltage, 6.5 → 36V dc Input Voltage, 2A Output Current,

New and advanced ultra-compact range of SIP packaged step down regulators from Tracopower. The TSR 2 series offers a direct drop-in upgrade to the antiquated LMxx series. Boasting up to 96% efficiency without the need for extra heat dissipation such as a heat sink.
Another main benefit of the TSR 2 series is the significant advantage of using switching regulators over linear variants. Benefits for making the transition include better output accuracy and a lower standby current.

Compatible with the LMxx series linear regulators.
Integral short circuit protection.
