For power supply transistor regulation, the equivalent power line resistance is 3
Ω or greater.
*2 : The upper limit for VCC op is VCC max–2V.
[Design Note]
Select the target PO under the a rated load/rated supply voltage conditions of RL = 3 to 8Ω and VCC = 5 to 18V. Make
sure that it does not exceed the package Pd max of 37.5W. Note that heavy load and high VCC conditions would bring
about power efficiency deterioration depending on the drive design employed.
