Description

Description
The YB1231 is a series of ultra-low-noise, low dropout (LDO) linear regulators with 2.0% output voltage accuracy. The YB1231 regulators achieve a low 440mV dropout at 600mA load current of 4.5V output and are available in voltages ranging from 3.2V to 4.5V with 0.1 V per step (custom voltage is considerable at request).
The YB1231 regulators are optimized to work with low-ESR and low cost ceramic capacitors, reducing the amount of board space critical in hand-held devices. The YB1231 requires only 2.2 μF output capacitor for stability with any load and consumes less than 1μA in shutdown mode.
Built-in thermal shutdown and short-circuit protect offer secure protection against fault operation. The YB1231 regulators are available in SOT-23 / SOT-25 / SOT-89 packages.
