Output Voltage (Vout): Determine whether a fixed or adjustable output is required. Common output levels include 1.8V, 3.3V, and 5V.
Load Current (Iout): Estimate both average and peak current demands during operation.
These parameters will help you filter between linear and switching regulator topologies.
