LFXX Very low drop voltage regulator with inhibit function Datasheet - production data Description The LFXX is a very low drop regulator available in TO-220, TO-220FP, DPAK and PPAK packages and in a wide range of output voltages. The low drop voltage (0.45 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and especially in battery- powered systems. In the 5 pin configuration (PPAK) a shutdown logic control function is available (pin 2, TTL compatible). This means that when the device is used as a local regulator, a part of the board can be put in standby, decreasing the total power consumption. In the Features three terminal configuration, the device has the  Very low-dropout voltage (0.45 V) same electrical performance, but it is fixed in ON  Very low quiescent current (typ. 50 µA in state. It requires a capacitor of only 2.2 µF for OFF mode, 500 µA in ON mode) stability, saving board space and costs. The  Output current up to 500 mA LFXX is available as automotive grade in DPAK  Logic-controlled electronic shutdown and PPAK packages, for the options of output voltages whose commercial part numbers are  Output voltages of 1.5; 1.8; 2.5; 3.3; 4.7; 5; shown in the order codes. These devices are 6; 8; 8.5; 9; 12 V qualified according to the specification  Automotive grade product: 1.8 V, 2.5 V, AEC-Q100 of the automotive market, in the 3.3 V, 5.0 V, 8.0 V, 8.5 V V in DPAK and OUT temperature range -40 °C to 125 °C, and the PPAK packages statistical tests PAT, SYL, SBL are performed.  Internal current and thermal limit  Only 2.2 µF for stability  Available in ±1% (AB), ±1.5% (AC) or ±2% (C) selection at 25 °C  Supply voltage rejection: 80 db (typ.)  Temperature range: from -40 to 125 °C May 2017 DocID2574 Rev 31 1/53 This is information on a product in full production. www.st.com
