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 regu-
lators when energy efficiency is a parameter of the design. The high efficiency up
to 97 % allows full load operation up to +80°C (+90°C with 50% load) ambient
temperature without the need of forced aircooling.
Excellent output voltage accuracy and low standby current are other features that-
distinguish switching regulators from linear regulators.
