com 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.
