  • Up to 96% efficiency – No heat-sink required
  • Pin compatible with LMxx linear regulators
  • SIP-package fits existing TO-220 footprint

The TSR 1 series step-down switching regulators are drop-in replacement for

  • Built in filter capacitors

inefficient 78xx linear regulators. A high efficiency up to 96% allows full load

  • Operation temp. range –40°C to +85°C operation up to +60°C ambient temperature without the need of any heat-sink

or forced cooling. The TSR 1 switching regulators provide other significant fea-

  • Short circuit protection

tures over linear regulators, i.e. better output accuracy (±2%), lower standby

  • Wide input operating range

current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution

  • Excellent line / load regulation

for many battery powered applications.

  • Low standby current
  • 3-year product warranty
