YB1210

YB1210 – 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.
