What's LDO?

LDOJ is low dropout regulator, low dropout + linear + voltage regulator. "Low dropout": The output voltage drop is relatively low, for example, the input is 3.3V, and the output can reach 3.2V. "Linear": The MOS tube inside the LDO works on a linear resistance. "Voltage regulator" shows that the purpose of the LDO is to stabilize the power supply. Since the general LDO package is much smaller than DC-DC, and the cost is much lower, so in many factories, we will use LDO to convert the voltage we need. Of course, under the premise of choosing to use LDO, It is necessary to meet basic requirements such as response to noise and power consumption.
