LX8211 I N T E G R A T E D P R O D U C T S 150mA CMOS Low Dropout Regulator P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES W W W. Microsemi . COM The LX8211 fixed/adjustable voltage linear regulators combines low dropout, high accuracy, ultra-low ground current and fast response in a very small footprint. Using the Enable pin the regulators is switched on with TTL logic levels, which is especially useful for batteryoperated equipment. Other features include independent Thermal and Short Circuit Current protection. The regulator is stable with a low value ceramic output capacitors. For ultra low noise operation a Bypass pin is brought out to connect an optional capacitor. Significant performance improvements over Bipolar technology are achieved designing in CMOS: increased regulator efficiency by minimizing operating ground current (typ<140uA) and it is nearly eliminated (typ<1uA) in shutdown. The PMOS output transistor allows for ultra low dropout typically less than 300mV at 100mA. ! Dropout Voltage typically 175mV @ 100mA ! Ultra low shutdown Current typically less than 1uA ! High Output accuracy trimmed to 0.25% ! Standard pinout in SOT-23-5 ! Noise Bypass feature available ! Current and Over Temperature protection !
