Enable. Pull high to enable the output, low to disable the output. This pin has no internal bias and
must be tied to the input voltage, or actively driven.
Input Supply Pin.

Regulated Output Voltage Pin.
The feedback to the internal Error Amplifier to set the output voltage.
The Thin TO-263 DAP is used as a thermal connection to remove heat from the device to an
external heat-sink in the form of the copper area on the printed circuit board. The DAP is physically
connected to backside of the die. The DAP is internally connected to device ground. The DAP
should be soldered to the Ground Plane copper.
Regulated Output Voltage Pins. Pins 1 and 2 share current and must be connected together.
The feedback to the internal Error Amplifier to set the output voltage.
No internal connection

Enable. Pull high to enable the output, low to disable the output. This pin has no internal bias and
must be tied to the input voltage, or actively driven.
Input Supply Pin. Pins 7 and 8 share current and must be connected together.
The PSOP-8 DAP is used as a thermal connection to remove heat from the device to an external
heat-sink in the form of the copper area on the printed circuit board. The DAP is physically
connected to backside of the die, but is not internally connected to device ground. The DAP should
be soldered to the Ground Plane copper.
