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 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.
