RT9032
Programmable Dual Output Linear Regulator
General Description
Features
The RT9032 is a dual channels, low noise and low dropout
Wide Operating Voltage Ranges : 2.5V to 5.5V
voltage regulator souring up to 300mA at each channel.
Dual LDO Output
The output voltage range is from 1.1V to 3.3V by operating
Pin Programmable Output Voltage
voltage range from 2.5V to 5.5V.
Low-Noise for RF Application
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.
No Noise Bypass Capacitor Required
Fast Response in Line/Load Transient
