LP38690SD-ADJ
This is the input supply voltage to the regulator. For LLP package devices, both V
together for full current operation (500mA maximum per pin).
Circuit ground for the regulator. For the SOT-223 package this is thermally connected to the die and
functions as a thermal connection when the soldered down to a large copper plane.
Regulated output voltage.
The enable pin allows the part to be turned ON and OFF by pulling this pin high or low.
The adjust pin is used to set the regulated output voltage by connecting it to the external resistors R1
and R2 (see Typical Application Circuit).
LLP Only - The DAP (Exposed Pad) functions as a thermal connection when soldered to a copper
plane. See
