1 / 10 page  Preliminary RT9182 DS9182-02 April 2002 www.richtek-ic.com.tw 1 Dual, Low-Noise, 200mA LDO Regulator General Description The RT9182 is a dual-channel, low noise, and low dropout regulator supplying up to 200mA current at each channel. The output voltage ranges from 1.5V to 3.3V in 100mV increments and 2% accuracy by operating from a +2.7V to +6.5V input. The RT9182 uses an internal PMOS as the pass device, which consumes 165 µA supply current (both LDOs on) independent of load current and dropout conditions. The SHDN pin controls both outputs simultaneously and consumes nearly zero operation current in the disable mode making the IC suitable for battery-power devices. Other features include a reference voltage bypass pin to improve low noise performance, current limiting, and over temperature protection. Ordering Information RT9182 Features • Up to 200mA Output Current (Each LDO) • Shutdown Function • 29µµµµVRMS Low Noise Output • Current Limiting and Thermal Protection • Short Circuit Protection • 120mV Dropout at 100mA Load • Two LDOs in SOT-26 Package Applications Cellular Phones Laptop, Notebook, and Palmtop Computers Battery-powered Equipment Hand-held Equipment Pin Configurations Part Number Pin Configurations RT9182 CE (Plastic SOT-26) TOP VIEW 1.
