DESCRIPTION
Input voltage pin. A minimum 0.1µF X5R/X7R capacitor is required for proper operation.
Pins have internal termination and can be left unconnected. Connection to ground is optional.
High on this pin enables the device.
Ground pin.
In the adjustable output voltage option, this pin is connected to the external feedback resistor divider which sets
the LDO output voltage. In the 3.3V and 5V options, this pin is not used and can be connected to ground.
Regulated output voltage. A 10µF X5R/X7R output capacitor is required for stability.
It is recommended to solder the EPAD to the ground plane.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil 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). Intersil
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.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL78307. For more information on MSL please see techbrief TB363.
