RP101x Series
Low Supply Current/Low Noise 300mA LDO
The RP101x Series are CMOS-based LDO regulators featuring 300mA output. Various basic performances of the RP Series have been
improved by adopting a new manufacturing process. RP101x has the supply current as low as 18μA, which is far lower than current
products. Due to a built-in transistor with low on-resistance of 0.87Ω (at VOUT=2.8V) , RP101x provides a low dropout voltage. RP101x
also has an excellent line transient response, 75dB ripple rejection, and low noise. The output voltage accuracy has been improved
to ± 0.6% and the temparature drift coefficient of the output voltage is as low as ± 30ppm/°C

WHAT IS DFN(PLP)1612-4/DFN(PLP)1612-4B?
The DFN(PLP)package is a leadless package using an electroforming sheet in place of lead frame.
This extremely compact package features increased power dissipation and conversion to thinner type.
The name is representing a combination of the body size and the number of pins, i.e., DFN(PLP)1612-4
stands for the body size of 1.6mm×1.2mm and 4 pins.
DFN(PLP)1612-4 is 0.6mm thick while the thickness of DFN(PLP)1612-4B was reduced to 0.4 mm.
An environment-friendly, leadfree package with gold plated contacts complies with the RoHS Directive.
