YB1200R
150mA High PSRR with Auto-Discharge LDO Regulator
Description
The YB1200R is a series of ultra-low-noise,
low dropout (LDO) linear regulators with
2.0% output voltage accuracy. The
YB1200R regulators achieve a low 180mV
dropout at 150mA load current of 3.3V
output and are available in voltages
ranging from 1.2V to 3.6V with 0.1V per
step (custom voltage is considerable at
request).
The YB1200R regulators are optimized to
work with low-ESR and low cost ceramic
capacitors, reducing the amount of board
space critical in portable devices. The
YB1200R requires only 0.47μF output
capacitor for stability with any load and
consumes less than 1μA in shutdown mode.
YB1200R also deploys an auto-discharge
circuit which can de-energize the output
capacitor to prevent the system from
abnormal operation during shutdown.
Built-in thermal shutdown and short-circuit
protect offer secure protection against fault
operation. The YB1200R regulators are
available in SC-70 / SC-82 packages.
