ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VRS+ = 0 to +28V, VCC = +3V to +28V, VSENSE = 0, TA = TMIN to TMAX, RLOAD = ∞ unless otherwise noted. Typical values are at

TA = +25°C.) (Note 1)

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.

VCC, RS+, RS- to GND .......................................... -0.3V to +30V

OUT to GND .............................................. -0.3V to (VCC + 0.3V)

Output Short-Circuit to VCC or GND ......................... Continuous

Differential Input Voltage (VRS+ - VRS-) ............................. ±0.3V

Current into Any Pin......................................................... ±20mA

Continuous Power Dissipation (TA = +70°C)

8-Pin SO (derate 5.88mW/°C above +70°C)............... 471mW

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

Operating Temperature Range .......................... -40°C to +85°C

Storage Temperature Range ............................ -65°C to +150°C

VRS+ > +2.0V

(Note 2)

Guaranteed by PSR test

VSENSE = +100mV, VCC = +12V, VRS+ = +12V

VSENSE = VRS+ - VRS-

VCC = +12V, VRS+ =+12V, VSENSE = +6.25mV

(Note 4)

VSENSE = +100mV, VCC = +12V, VRS+ = +0.1V

VRS+ ≤ +2.0V

VRS+ > +2.0V

VRS+ > +2.0V, VCC = 12V

VCC = 0

VRS+ > +2.0V

VSENSE = +100mV, VCC = +28V, VRS+ = +28V

VRS+ ≤ +2.0V

VSENSE = +100mV, VCC = +12V, VRS+ = +12V,
