The new TSR-1SM series models of step-down switching regulators have a
high efficiency up to 96% which allows full load operation up to +65°C ambi-
ent temperature without the need of any heat transmission layer. Excellent out-
put voltage accuracy (±2%) and low standby current (~1 µA) are features that
distinguish these switching regulators from linear regulators.
