RT9086 Datasheet | Richtek

Description The RT9086 is a high performance positive low dropout (LDO) regulator designed for applications requiring very low dropout voltage and ultra-high Power Supply Ripple Rejection (PSRR) low noise, low quiescent current that can supply up to 250m A output current. The input voltage range is from 2.2V to 5.5V. The device is designed to work with a 1F input and a 1F output ceramic capacitor (no separate noise bypass capacitor is required). The RT9086 features a precise 2% output regulation over line, load, and temperature variations in WL-CSP-4B 0.67x0.67 (BSC) package. The output voltage is available from 1.2V to 4.5V in 25m V steps. The remended junction temperature range is - 40C to 125C, and the ambient temperature range is - 40C to 85C.
