TSR 0.5 is a series of step-down non-isolated switching regulators in compact
SIP package. These converters are an ideal drop-in replacement to LM78 linear
regulators when energy efficiency is a parameter of the design. The high effi-
ciency up to 97% allows full load operation up to +80°C (+90°C with 50%
load) ambient temperature without the need of forced air cooling.
Excellent output voltage accuracy and low standby current are other features
that distinguish witching regulators from linear regulators.
