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.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective single layer thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Note 5. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
Note 6. It is guaranteed by design.
