... that are direct replacements to the clumsy and crude 7805 regulator. With this device, just drop it in your circuit as if it\'s something like an LM317 (+Vin, ADJ, +Vout). You don\'t even have to worry about miswiring the pins; this pinout is exactly the same as the 7805\'s/LM317\'s pinout!
OK, so why swap? Because this device is a dedicated switching regulator, complete with a on-board precision oscillator and output MOSFET stage that does the actual hi-speedswitching. This differs from LM317/7805 operation, which does little more thanregulates an inputvoltage level to an imprecise output voltage or current level.
What does a precision switching effect have on the purity and efficiency of the +5Vdc output? It means you\'re getting a 95% efficient output. This is why you don\'t need a heatsink, and why the low, low20-60% efficiencies of 7805\'s do need a heat sink.

Some specificatuions:

• up to 500 mA current output
• pin compatible with LM7805 linear regulators
• non-isolated switching regulator
• high start-up current capability
• wide input voltage range
• efficiency 95%
• low ripple and noise
• short circuit protection
• ultra-compact SIP3 package
• -40°C to +85°C temperature range
