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 wide range of output voltages. The very low-dropout voltage (0.2 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and in battery- powered systems. This device is pin-to-pin compatible with the L78L series. Furthermore, in the 8-pin configuration (SO-8), it uses a shutdown logic control (pin 5, Features TTL compatible). This means that when the Very low-dropout voltage (0.2 V typ.) device is used as a local regulator, a part of the Very low quiescent current (typ. 50 A in board can be put in standby, decreasing the total OFF mode, 0.5 mA in ON mode, no load) power consumption. In the three-terminal Output current up to 100 mA configuration (TO-92), the device is always in Output voltages: 3 V, 3.3 V, 4.5 V, 5 V, 8 V on-state. It requires a 2.2 F capacitor for Internal current and thermal limit stability, 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: Device summary Order code Output voltage (V) SO-8 TO-92 (Ammopack) TO-92 (tape and reel) LE30CD-TR 3 LE33CD-TR LE33CZ-AP LE33CZ-TR 3.3 LE45CD-TR 4.5 LE50ABD-TR LE33ABZ-AP 5 LE50CD-TR 5 LE80CD-TR 8 May 2017 DocID2573 Rev 15 1/24 www.st.com This is information on a product in full production.
