RichTek Technology Corporation Ldo, Adj, 0.5-3V, 1A, Wlcsp-6; Output Type Richtek RT9085AWSC

The RT9085A is an adjustable low dropout (LDO) linear regulator designed for applications requiring low input voltage and ultra-low dropout voltage. It supports an input voltage range from 0.8V to 5.5V and can provide an adjustable output voltage from 0.5V to 3V with a maximum output current of 1A. The device features an ultra-low dropout voltage of 60mV at 1A, making it suitable for scenarios where the output voltage is close to the input voltage. The RT9085A has a low quiescent current of approximately 35OºA in operating mode and only 0.5OºA in disable mode, which is advantageous for battery-powered and portable applications. It includes an output active discharge function and is stable with a 10OºF output ceramic capacitor. The device is housed in a compact WL-CSP-6B package measuring 0.8mm x 1.2mm, making it suitable for space-constrained designs. Additionally, it is RoHS compliant and halogen/Pb free, aligning with environmental standards.
