Direct Paralleling, High Power Density LDO

Focus:

A new linear regulator architecture allows LDO output to be adjusted all the way down to 0 V using a single resistor. LDOs with this architecture can be easily paralleled for current sharing and for distribution of heat across the pc board and an all-surface-mount design.

What you’ll learn:

• How to understand operation of the LT3080 low dropout linear regulator (LDO)
• How to parallel LT3080 LDOs for current sharing and distribution of heat dissipation across the pc board
