FEATURES
● 3.3V/0.5A, 5V/0.5A or 12V/0.4A outputs; Pin and size-compatible with LM7805 & LM7812 regulators● Up to 95% efficiency – no heat sinks or thermal derating required!
● Two SIP-packages fit existing TO-220 footprints: Vertical-pin models occupy less than 0.1 square in. Optional horizontal pins provide 0.350 in. installed height
● +7.5-36Vdc operating input range; Low 3mA quiescent current
● Built-in filter capacitors – no external components required
● –40 to +70°C operation at full load; Short-circuit protection
● Excellent load (±0.2%) and line (±0.3%) regulation
● Ideal for powering instrumentation from 9V/12V/24V/28V supplies or batteries
● Can be used with unregulated dc supplies 3.3V/5V/12V Outputs High-Efficiency Switching Regulators with LM78XX Pinouts DATEL’s 7805SR (5V output), 7812SR (12V output) and 7803SR (3.3V output) step-down switching regulators are modern drop-in replacements for older, inefficient, LM7805 and LM7812 linear regulators. The 78XXSR's are pin- and sizecompatible with industry-standard TO-220 SIP packages.
