Programmable Dual Output Linear Regulator

RT9032

Update Alert Share

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 32μA 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.
