●No output or PSRR bypass capacitors required

●Improved “Click and Pop” suppression circuitry

●Very fast turn on time: 5ms (typ)

●Minimum external components

●2.6 - 5.5V operation

●BTL output can drive capacitive loads

●Ultra low current shutdown mode (SD Low)

●Applications

●Portable computers

●Desktop computers

●Multimedia monitors
