Your power supply problems just got SOLVED! These DC/DC converter step-down switching regulators are drop-in replacements for inefficient 78xx linear regulators. The little module may look tiny but inside is a high efficiency converter (up to 91%) which can output 1 Amp at 3.3V with up to +60°C ambient temperature without the need of any heat-sink or forced cooling.

The TSR-1 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.

  • 3.3V regulated output from 4.75 – 32VDC input
  • Up to 91 % efficiency – No heat-sink required
  • Pin compatible with LMxx linear regulators
  • SIP-package fits existing TO-220 footprint
  • Built in filter capacitors
  • Operation temp. range –40°C to +85°C
  • Short circuit protection
  • Wide input operating range
  • Excellent line / load regulation
  • Low standby current
  • 3-year product warranty
