ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(V+ = +12V, T

A

= -40°C to +125°C, unless otherwise noted. Typical values are at T

A

= +25°C.) (Note 2)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Voltages Referenced to GND
V+ ...........................................................................-0.3V to +13V
IN+, IN-...................................................................-0.3V to +14V
N_OUT, P_OUT ............................................-0.3V to (V+ + 0.3V)
N_OUT Continuous Output Current (Note 1) ....................390mA
P_OUT Continuous Output Current (Note 1).....................100mA

Continuous Power Dissipation (T

A

= +70°C)

6-Pin SOT23 (derate 8.7mW/°C above +70°C)............696mW

Operating Temperature Range .........................-40°C to +125°C
Storage Temperature Range .............................-65°C to +150°C
Junction Temperature ......................................................+150°C
Lead Temperature (soldering, 10s) .................................+300°C

Note 1: Continuous output current is limited by the power dissipation of the SOT23 package.
