Function
Ground
Input Supply (LP38500 only). Input Supply pins share current and must be connected
together on the PC Board.
Enable (LP38502 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.
Input Supply. Input Supply pins share current and must be connected together on the PC
Board.
Regulated Output Voltage. Output pins share current and must be connected together on the
PC Board.
Sets output voltage
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.
