600mA Low-Noise LDO Regulator

YOBON TECHNOLOGIES,INC. 

YB1230 – 600mA

Low-Noise LDO Regulator

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).

The YB1230 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

YB1230 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 YB1230 regulators are

available in SOT-23 / SOT-25 / SOT-89

packages.
