微源芯片 LP3980S 500mA低壓差線性穩(wěn)壓器
General Description
The LP3980S is designed for portable RF and wireless applications demanding performance and space requirements. The LP3980S performance 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 LP3980S also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The LP3980S consumes less than 0.03µA 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.
