NOTES:
1. Add “-T*” suffix for tape and reel.
2. These Altera Enpirion Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb
and Pb-free soldering operations). Altera Enpirion Pb-free products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

EPAD
Input voltage pin. A minimum 0.1µF ceramic capacitor is required for proper operation. Range 6V to 40V.
Enable pin. High on this pin enables the device. Range 0V to V_IN.
Ground pin.
This pin is connected to the external feedback resistor divider which sets the LDO output voltage. Range 0V to
3V.
Regulated output voltage. A 10µF ceramic capacitor is required for stability. Range 0V to 12V.
It is recommended to solder the EPAD to the ground plane.
