Detailed description
LD3980
TA is the ambient temperature
θ JA thermal resistance.
The device's pins perform the dual function of providing an electrical connection as well as
channeling heat away from the die. Use wide circuit-board traces and large, solid copper
polygons to improve power dissipation. Using multiple vias to buried ground planes further
enhances thermal conductivity.

Output capacitance
The device is specifically designed to employ ceramic output capacitors as low as 1µF.
Ceramic capacitors below 10µF offer significant cost and space savings, along with high
frequency noise filtering. Higher values and other types of capacitor may be used, but their
equivalent series resistance should be maintained in the range of the table.
