RP1228 - RichPower

RP1228 Portable Power Management 300mA Dual LDO Regulator

The RP1228 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 RP1228 offers 2% accuracy, extremely low dropout voltage (240mV @ 300mA), and extremely low ground current, only 27µA per LDO. The shutdown current is near zero cur.

Features

include current limiting, over temperature, output short circuit protection. The RP1228 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 RP1228 can operate stably with very small ceramic output capacitors, reducing required board space and component cost. The RP1228 is available in fixed output voltages in the SOT-23-6 package. Ordering Information Features Wide Operating Voltage Ranges : 2.5V to 5.5V Low-Noise for RF Application No Noise Bypass Capacit.
