150m A High PSRR with Auto-Discharge LDO Regulator Description The YB1200R is a series of ultra-low-noise, low dropout (LDO) linear regulators with 2.0% output voltage accuracy. The YB1200R regulators achieve a low 180m V dropout at 150m A load current of 3.3V output and are available in voltages ranging from 1.2V to 3.6V with 0.1V per step (custom voltage is considerable at request). The YB1200R regulators are optimized to work with low-ESR and low cost ceramic capacitors, reducing the amount of board space critical in portable devices. The YB1200R requires only 0.47μF output capacitor for stability with any load and consumes less than 1μA in shutdown mode. YB1200R also deploys an auto-discharge circuit which can de-energize the output capacitor to prevent the system from abnormal operation during shutdown. Built-in thermal shutdown and short-circuit protect offer secure protection against fault operation. The YB1200R regulators are available in SC-70 / SC-82 packages.
