This paper research and design a precision adjustable power supply. Thevoltage in the range of 3.3V to 3.4V, the ripple voltage and its peak value of not more than 100mV, power is about 1W, the power supply can be provided to theoptical module, its security is good, and can support the RF device,the power supply starting surge voltage time close to 0. In the choice of method of removing surge ripple, designed a rated output voltage 5V, rated output current of 1A low dropout linear regulator (LDO), the device is compared to the DC/DC circuit, effectively reducing the ripple. By experimental verification, the design scheme is feasible, and has good application value.
