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.
