Linear LDO Voltage Regulators Microchip Technology

WebLDO is an acronym that means Low Dropout. You can also call it a saturation or low-loss type of linear regulator. And it functions at a low PD (potential difference) between input and output voltage supply. The LDO regulator can only take input voltages that are a bit larger than the preferred output voltage. WebLow-dropout regulators are distinguished by their ability to maintain regulation with small differences between supply voltage and load voltage. For example, as a lithium-ion battery drops from 4.2 V (fully charged) to …

Linear LDO regulators are a simple solution for using an integrated circuit to regulate a higher voltage to a lower voltage without the use of an inductor. Power management is vital in a world driven by battery-powered small devices that require efficient power consumption and precision.

WebLDO would be adequate. Why not 2x bucks? Because a buck requires more components (inductor and better capacitor) than LDO. In this case, the combination of buck and LDO is a compromise of efficiency vs. cost and size. It's not uncommon to use an LDO to power RF communication, analog front ends, because these can be susceptible to the EMI.
