RT9182

Preliminary RT9182 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 +5.5V input. The RT9182 uses an internal PMOS as the pass device, which consumes 165μA supply current (both LDOs on) independent of load current and dropout conditions. The EN1 and EN2 pins control each output respectively. When both outputs shutdown simultaneously, the chip will be turn off and consumes nearly zero operation current which is suitable for battery-power devices. Other features include a current limiting, and over temperature protection.
