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.
