ZHCSI81L February 2009 – May 2018 LM26420
PRODUCTION DATA.
The LM26420 features an open drain power good (PG) pin to sequence external supplies or loads and to provide fault detection. This pin requires an external resistor (RPG) to pull PG high when the output is within the PG tolerance window. Typical values for this resistor range from 10 kΩ to 100 kΩ.
