Low-Cost, Low-Dropout, Dual Linear Regulator

Maxim Integrated 

Low-Cost, Low-Dropout, Dual Linear Regulator

ABSOLUTE MAXIMUM RATINGS

IN1, IN2 to GND (Note 1).....................................................±12V

SET1, SHDN1, PWROK1 to GND.............. -0.3V to (VIN1 + 0.3V)

SET2, SHDN2, REF2 to GND ....................... -0.3V, (VIN2 + 0.3V)

Output Short-Circuit Duration ............................................Infinite

Continuous Power Dissipation (TA = +70°C)

16-Pin Narrow SO (derate 20mW/°C above +70°C) ............... 1W

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

Junction Temperature .....................................................+150°C

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

Lead Temperature (soldering, 10sec) ............................ +300°C

Note 1: Connect SHDN1 to IN1 and SHDN2 to IN2 through 20kΩ resistors to limit current flow in case a battery is reversed.

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.

ELECTRICAL CHARACTERISTICS (Notes 2, 3)

(VIN_ = VOUT_(TYP) + 1V, TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
