    Products Detail

    The RT9187C is a 600mA low-dropout (LDO) regulator with ultra-low noise, high PSRR, and ultra-fast transient response. It features a noise reduction pin for further output noise reduction, operates from 2.5V to 5.5V input, and requires only 2.2μF ceramic output capacitor for stability. Key protections include current limiting and thermal shutdown. The device consumes <0.1μA in shutdown mode and is designed for portable RF/wireless applications where board space is critical.

    Key Features

    • Ultra-Low-Noise for RF Application, Ultra-Fast Response in Line/Load Transient, <0.1μA Standby Current When Shutdown, Low Dropout: 100mV at 500mA, Wide Operating Voltage Ranges: 2.5V to 5.5V, TTL-Logic-Controlled Shutdown Input, Current Limiting Protection, Thermal Shutdown Protection, Only 2.2μF Output Capacitor Required for Stability, High Power Supply Rejection Ratio, RoHS Compliant and Halogen Free
