Preliminary
RT9184
500mA Dual LDO Regulator
General Description
The RT9184 is a dual-channel, low noise, and low
dropout regulator supplying up to 500mA current at
each channel. The output voltage ranges from 1.5V
to 3.3V in 100mV increment and 2% accuracy by
operating from a +2.7V to +6.5V input.
The RT9184 uses two internal PMOS as the pass
device, which consumes 185µA supply current (both
LDOs on) independent of load current and dropout
conditions. Other features include a current limiting
and over temperature protection.
Applications
