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.
