YB1253 شرح
YB1253
300mA, Low Power, High PSRR LDO Regulator
Description
The YB1253 is a series of ultra-low-noise,
high PSRR, and low quiescent current low
dropout (LDO) linear regulators with 2.0%
output voltage accuracy. The YB1253
regulators achieve a low 300mA dropout at
300mA load current of 3.6V output and are
available in voltages ranging from 1.2V to
3.6V with 0.1 V per step (custom voltage is
considerate at request).
The YB1253 regulators are optimized to
work with low-ESR and low cost ceramic
capacitors, reducing the amount of board
space critical in portable devices. The
YB1253 requires only 1.0μF output
capacitor for stability with any load and
consumes less than 1μA in shutdown
mode.
Built-in thermal shutdown and short-circuit
current limit offer secure protection against
fault operation. YB1253 regulators also
include an auto-discharge function. The
YB1253 regulators are available in SOT-23
/ SOT-25 / SOT-89 packages.
