微源LDO穩(wěn)壓器 LP3983HAX5F SOT89-5封裝
General Description
The LP3983HAB5F is designed for portable RF and wireless applications with demanding performance and space requirements.
The LP3983HAB5F 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.
LP3983HAB5F also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices.
The LP3983H consumes less than 0.1μA in shutdown mode and has fast turn-on time less than 50μs.
The other features include ultra-low dropout voltage, high feedback accuracy, current limiting protection, and high ripple rejection ratio.
It is available in the 5-lead of SOT23-5 andSOT89-5 packages.
