Description
The YB1210R is a series of ultra-low-noise, low
dropout (LDO) linear regulators with 2.0% output
voltage accuracy. The YB1210R regulators achieve
a low 320mV dropout at 300mA load current of 3.3V
output and are available in voltages ranging from
1.2V to 3.6V with 0.1 V per step (custom voltage is
considerable at request).
The YB1210R regulators are optimized to work with
low-ESR and low cost ceramic capacitors, reducing
the amount of board space critical in portable
devices. The YB1210R requires only 1.0 μF output
capacitor for stability with any load and consumes
less than 1μA in shutdown mode.
Applications
Built-in thermal shutdown and short-circuit protect
offer secure protection against fault operation. The
YB1210R regulators are available in SOT-23 /
SOT-25 / SOT-89 packages.
