RP101x Series
Low Noise 0.6% Accuracy 300mA LDO
The RP101x Series are CMOS-based LDO regulators featuring 300mA output. 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 VSET=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.
