Your power supply problems just got SOLVED! These DC/DC converter step-down switching regulators are drop-in replacements for
inefficient 78xx linear regulators. The little module may look tiny but inside is a high efficiency converter (up to 91%) which can output 1 Amp at 3.3V with up to +60°C ambient temperature without the need of any heat-sink or
forced cooling.
The TSR-1 switching regulators provide other significant features over linear regulators,
i.e. better output accuracy (±2 %), lower standby current of 2 mA and no
requirement of external capacitors. The high efficiency and low standby power
consumption makes these regulators an ideal solution for many battery powered
applications.
