onsemi NCP151 LDO Regulators

onsemi NCP151 LDO Regulators are dual linear Low Dropout Regulators capable of supplying two independent 300mA output currents from a 1.7V input voltage. The NCP151 provides a wide output voltage range from 0.8V up to 3.6V. This device delivers a high 70dB at 1kHz Power Supply Rejection Ratio (PSRR), and very good dynamic performance as load/line transients. In connection with low quiescent current, the NCP151 is very suitable for various battery-powered applications such as tablets, smartphones, and wireless devices. Each output is fully protected in case of output overload, output short circuit conditions, and overheating, ensuring a very robust design.

The NCP151 LDO Regulators are housed in a compact 1mm x 1mm DFN−4 package, ideal for space-constrained applications. These devices are Pb-free, Halogen-free, BFR-free, and RoHS-compliant.
