Pin Functions
DESCRIPTION
Sets output voltage
Enable (LP38502-ADJ only). Pull high to enable the output, low to disable the output.
This pin has no internal bias and must be either tied to the input voltage, or actively
driven.
Ground
Input supply (LP38500-ADJ only). Input supply pins share current and must be
connected together on the PC board.
Input supply. Input Supply pins share current and must be connected together on the
PC board.
In the LP38500-ADJ, this pin has no internal connections. It can be left floating or used
for trace routing.
Regulated output voltage. Output pins share current and must be connected together on
the PC board.
The DAP is used to remove heat from the device by conducting it to a copper clad area
on the PCB which acts as a heatsink. The DAP is electrically connected to the backside
of the die. The DAP must be connected to ground potential, but can not be used as the
only ground connection.
