Description
The YB1200 family consists of a series of 150mA ultra-low-noise, low dropout (LDO) linear regulators especially designed for battery-powered RF and wireless applications. The YB1200 regulator achieves a low 250mV dropout at 150mA load current of 3.3V output, ultra-low output voltage noise of 15µVrms and PSRR of 57dB at 1KHz.
