YB1210 â 300mA
Ultra-Low-Noise, High PSRR LDO Regulator
Description
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.
Other features include high output voltage
accuracy and current limiting protection.
The YB1210 regulators are available in
SOT-23 / SOT-25 / SOT-89 packages.
