LX8221-AIDU

IC REG LDO ADJ 0.15A 10MSOP

The LX8221 contains two fixed voltage linear regulators combines low dropout, high accuracy, ultra-low ground current and fast response in a very small footprint. Each device can be powered from a separate supply voltage or the same supply voltage for maximum system flexibility.Using the Enable pin, the regulators is switched on with TTL logic levels, which is especially useful for battery-operated equipment. Other features include independent Thermal and Short Circuit Current protection. The regulators are 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<100uA and it is nearly eliminated typ<1uA in shutdown. The PMOS output transistor allows for ultra low dropout typically less than 300mV at 100mA.
