DC/DC Converter TSR 2 Series, 2 A Ultra compact SIP package 0.55 x 0.30 x 0.40 inch Up to 96 % efficiency - No heat-sink required Pin compatible with LMxx linear regulators Built in filter capacitors Operating temperature range -40C to +85C Excellent line / load regulation Short circuit protection 3-year product warranty The new TSR 2 series step-down switching regulators are drop-in replacement for inefficient LMxx linear regulators. A high efficiency up to 96 % allows full load operation up to +67C ambient temperature without the need of any heat-sink or forced cooling. The TSR 2 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.
