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 +67°C ambient temperature without the need of any
heat-sink or forced cooling. The TSR 2 switching regulators provide other sig-
nificant 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.
