The YB1210 family consists of a series of
300mA ultra-low-noise, low dropout (LDO)
linear regulators especially designed for
battery-powered
RF
and
wireless
applications. The YB1210 regulator
achieves a low 450mV dropout at 250mA
load current of 3.3V output, ultra-low output
voltage noise of 15µVrms and PSRR of
57dB at 1KHz.
The YB1210 regulators are also optimized
to work with low-ESR and low cost ceramic
capacitors reducing the amount of board
space critical in hand-held devices. The
YB1210 requires only 0.47 µF output
capacitor for stability with any load. The
YB1210 consumes less than 1µA in
shutdown mode.
