TSR-0.5SM is a series of step-down non–isolated switching regulators in compact

SIP package. These converters are an ideal alternative to LM78 linear regulators

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.

Models

1) For input voltage higher 24 VDC an input capacitor 22 µF/ 50 V is required

2) Input voltage must be higher than output voltage set:>1.5 V for 3.3–5.0V and >3 V for 6.5–15.0V
