Selecting Voltage Regulators
Your design requirements determine which voltage regulator you need.
The key to selecting a voltage regulator is understanding the regulator
parameters and how they relate to the design.
The following checklist can help you select the proper regulator for your
design:

■
Choose a Regulator Type
If required, select either a linear, asynchronous switching, or
synchronous switching regulator based on your output current, regulator
efficiency, cost, and board-space requirements. DC-to-DC converters
have output current capabilities from 1 to 8 A. You can use a controller
with an external MOSFET rated for higher current for higher-output-
current applications.
Calculate the Maximum Input Current
Use the following equation to estimate the maximum input current based
on the output power requirements at the maximum input voltage:
Where
60% for linear 2.5-V-to-1.5-V conversion, 45% for linear 3.3-V-to-1.5-V
conversion, and 30% for linear 5.0-V-to-1.5-V conversion.
Once you identify the design requirements, select the voltage regulator
that is best for your design.
