300 mA automotive LDOs are 2.9 x 2.8 mm


The BUxxJA3DG-C series can accept input voltages up to 6V and output voltages of 1.2, 1.8, 2.5, 3.0 or 3.3V depending on the version, with a voltage drop below 370mV (except 500mV for version 1.2 V, table below).

Rohm pointed out the possibility of adjusting the 1.2 V sensor from the 1.8 V bus, and regarding the 3.3 V version added: “the noise of the output voltage is reduced to only 55 μV (rms value) [see schedule], which is about 40% lower than comparable 3.3V low-noise LDO regulators.”

OV at the enable input reduces the current to 10 µA (2 µA at +85 or below). °C). When off, ~40 ohms are internally connected to the output pins to discharge the output capacitance.
