july 2007 rev. 18 1/45 45 lfxxab lfxxc very low drop voltage re gulators with inhibit features very low dropout voltage (0.45v) very low quiescent current (typ. 50 a in off mode, 500 a in on mode) output current up to 500 ma logic-controlled electronic shutdown output voltages of 1.5; 1.8; 2.5; 2.7; 3; 3.3; 3.5; 5; 6; 8; 8.5; 9; 12v internal current and thermal limit only 2.2 f for stability available in 1% (ab) or 2% (c) selection at 25c supply voltage rejection: 80db (typ.) temperature range: -40 to 125c description the lfxxab/lfxxc are very low drop regulators available in pentawatt, to-220, to-220fp, dpak and ppak package and in a wide range of output voltages. the very low drop voltage (0.45v) and the very low quiescent current make them particularly suitable for low noise, low power applications and specially in battery powered systems. in the 5 pins configuration (pentawatt and ppak) a shutdown logic control function is available (pin 2, ttl compatible). this means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. in the three terminal configuration the device has the same electrical performance, but is fixed in the on state. it requires only a 2.2 f capacitor for stability allowing space and cost saving. to-220fp pentawatt to-220 dpak ppak table 1. device summary order codes lf15c lf27ab lf40c lf80ab lf15ab lf30c lf40ab lf85c lf18c lf30ab lf50c lf85ab lf18ab lf33c lf50ab lf90c lf25c lf33ab lf60c lf90ab lf25ab lf35c lf60ab lf120c lf27c lf35ab lf80c lf120ab www.st.com
