General Description

The RT9032 is a dual channels, low noise and low dropout

voltage regulator souring up to 300mA at each channel.

The output voltage range is from 1.1V to 3.3V by operating

voltage range from 2.5V to 5.5V.

The output voltages of the RT9032 can be programmed by

setting the voltage of P1 and P2. There are 9 different

voltage settings in one chip. User can choose output

voltages easily by setting P1, P2 to VDD, GND or floating.

The RT9032 offers 3% accuracy, low dropout (330mV

@300mA) and extremely low ground current, only 32

μA

per LDO. The shutdown current is near to zero current

which is suitable for battery-powered device. Other

features include current limiting, over temperature

protection and output short circuit protection.

The RT9032 can operate stable with very small ceramic

output capacitors, reducing required board space and

component cost. The RT9032 is available in WDFN-8L

2x2 and WQFN-8L 1.6x1.6 (COL) packages.
