NCP151 LDO Dual Output High PSRR Regulators

ON Semiconductor’s NCP151 are dual linear regulators capable of supplying two independent 300 mA output currents from 1.7 V input voltage. These devices provide a wide output voltage range from 0.8 V up to 3.6 V. To optimize performance for battery operated portable applications; the NCP151 employs the dynamic quiescent current adjustment for very low IQ consumption at no load.
