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.
