描述 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 250mA output current. The input voltage range is from 2.2V to 5.5V. The device is designed to work with a 1μF input and a 1μF 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 25mV steps.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
