LExxAB LExxC Very low drop voltage regulators with inhibit Features ■ Very low dropout voltage (0.2 V typ) ■ Very low quiescent current (typ. 50 µA in OFF MODE, 0.5 mA in ON MODE, no load) ■ Output current up to 100 mA ■ Output voltages of 2.5; 2.7; 3; 3.3; 3.5; 4; 4.5; 4.7; 5; 8 V ■ Internal current and thermal limit ■ Only 2.2 µF for stability ■ Available in ± 1 % (A) or ± 2 % (C) selection at 25 °C ■ Supply voltage rejection: 80 dB (typ.) ■ Temperature range: -40 to 125 °C TO-92 Description The LExxAB and LExxC are very low drop voltage regulators available in SO-8 and TO-92 packages and in a wide range of output voltages. SO-8 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, maintaining the same electrical performances. It needs only 2.2 µF capacitor for stability allowing room and cost saving effect. The very low drop voltage (0.2 V) 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 compatible with the older L78Lxx series. Furthermore in the 8 pin configuration (SO-8) they employ a shutdown logic control (pin 5, TTL compatible). This means that when the device is used as a local regulator, Table 1.

Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach flag. 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. Table 3.

Test circuit Note: If the Inhibit pin is left floating, the regulator is in ON mode.
