LEXX Very low-dropout voltage regulator with inhibit function Datasheet - production data Description The LEXX is a very low-dropout voltage regulator available in SO-8, TO-92 packages and over a 3 2 1 wide range of output voltages. TO-92 SO-8 The very low-dropout voltage (0.2 V) and low Tape and reel TO-92 quiescent current make it particularly suitable for Ammopack Bag low-noise, low-power applications and in battery- powered systems. This device is pin-to-pin compatible with the L78L Features series. Furthermore, in the 8-pin configuration (SO-8), it uses a shutdown logic control (pin 5, Very low-dropout voltage (0.2 V typ.) TTL compatible). This means that when the Very low quiescent current (typ. 50 A in OFF device is used as a local regulator, a part of the mode, 0.5 mA in ON mode, no load) board can be put in standby, decreasing the total Output current up to 100 mA power consumption. In the three-terminal configuration (TO-92), the device is always in on- Output voltages: 3 V, 3.3 V, 4.5 V, 5 V, 8 V state. It requires a 2.2 F capacitor for stability, Internal current and thermal limit reducing the component size and cost. Small 2.2 F capacitor 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 Table 1.
