(Note 2)

SOP-8 (Exposed Pad) -------------------------------------------------------------------------- +60°C/W

TDFN-10 (3mmx3mm) ------------------------------------------------------------------------- +65°C/W

● Package Thermal Resistance, (θ

JC)

(Note 2)

SOP-8(Exposed Pad) --------------------------------------------------------------------------- +15°C/W

TDFN-10(3mmx3mm) -------------------------------------------------------------------------- +30°C/W

Note 1：Stresses beyond this listed

under “Absolute Maximum Ratings" may cause permanent damage to the device.

Note 2：

θJA is measured at 25°C ambient with the component mounted on a high effective thermal conductivity 4-layer

board of JEDEC-51-7.

θJC is measured at the exposed pad. The thermal resistance greatly varies with layout, copper

thickness, number of layers and PCB size.

Recommended Operating Conditions

● Supply Voltage V

IN ---------------------------------------------------------------------------- -------------- +4.5V to +18V

● Operation Temperature Range --------------------------------------------------------------------------- -40°C to +85°C
