Description
The YB1230 is a series of low-noise, low dropout (LDO) linear regulators with 2.0% output voltage accuracy. The YB1230 regulators achieve a low 500mV dropout at 600mA load current of 3.1V output and are available in voltages ranging from 1.8V to 3.1 V with 0.1 V per step (custom voltage is considerable at request).
