ACE5050LA  
500mA High PSRR, Ultra-low Noise, Ultra-Fast CMOS LDO Regulator  
Description  
The ACE5050LA is designed for portable applications with demanding performance and space  
requirements. The ACE5050LAperformance is optimized for battery-powered systems to deliver ultra-low  
noise and low quiescent current. Regulator ground current increases only slightly in dropout, further  
prolonging the battery life. The ACE5050LA also works with low-ESR ceramic capacitors, reducing the  
amount of board space necessary for power applications, critical in hand-held wireless devices. The  
ACE5050LA consumes only 0.1µA current in shutdown mode and has fast turn-on time (Typical 100µs).  
The other features include ultra- low dropout voltage, high output accuracy, current limiting protection,  
and high ripple rejection ratio.
