RP1230

Preliminary RP1230 Portable Power Management 300mA Dual LDO Regulator General Description The RP1230 is a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The range of output voltage is from 1.2V to 3.6V by operating from 2.5V to 5.5V input. The RP1230 offers 2% accuracy, extremely low dropout voltage (240mV @ 300mA), and extremely low ground current, only 27µA per LDO. The shutdown current is near zero current which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. The RP1230 is short circuit thermal folded back protected. The IC lowers its OTP trip point from 165°C to 110°C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users. The RP1230 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RP1230 is available in fixed output voltages in the SOT-23-6 package.
