A6303A
CMOS LOW DROPOUT REGULATOR (LDO)
300mA ULTRA-LOW NOISE, ULTRA-FAST RESPONSE
DESCRIPTION
The A6303A is designed for portable RF and
wireless applications with demanding
performanceand space requirements.
The A6303A performance is optimized for
battery –powered systems to deliver ultra low
noise and low quiescent current. Regulator
ground currentincreases only slightly in dropout,
furtherprolonging the battery life.
The A6303A also works with low-ESR ceramic
capacitors, reducing the amount of board space
necessary for power applications, critical in
hand-held wireless devices. The A6303A
consumes less than 0.01μA in shutdown mode
and has fast turn-on time less than 50μs. The
other features include ultra low dropout voltage,
high output accuracy,current limiting protection
and high ripple rejection ratio.
The A6303A is available in SOT-23, SOT-25 and
SC70-5 Packages.
