IPTION The LE00 regulator series are very Low Drop regulators available in SO-8 and TO-92 packages and in a wide range of output voltages. The very Low Drop voltage (0.2V) and the very low quiescent current make them particularly suitable for Low Noise Low Power applications and specially in battery powered systems. They are pin to pin patible with the older L78L00 series. Furthermore in the 8 pin configuration (SO-8) they employ a Shutdown Logic Control (pin 5, TTL patible). This means that when the device is used as a local SCHEMATIC DIAGRAM TO-92 regulator, it’s possible to put in stand by a part of the board even more decreasing the total power consumption. In the three terminal configuration (TO-92) the device is even in ON STATE, mantaining the same electrical performances. It needs only 2.2µF capacitor for stability allowing room and cost saving effect.

This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate area of copper on the printed circuit board is available for heatsinking. The external dimensions are the same as for the standard SO-8 TEST CIRCUITS Note: If the Inhibit pin is left floating, the regualtor is in ON mode. However, to avoid any noise picking-up, it is suggested to ground it when 2/25 LE00AB/C CONNECTION DIAGRAM AND ORDERING NUMBERS (top view) BOTTOM VIEW pin 1 = OUT pin 2 = GND pin 3 = IN SO-8 TO-92 ORDERING NUMBERS Type LE12AB LE12C LE15AB LE15C LE25AB LE25C LE27AB LE27C LE30AB LE30C LE33AB LE33C LE35AB...
