ABSOLUTE MAXIMUM RATINGS

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.

Input Supply Voltage ...........................................................+18V

Output Short Circuited to Ground.........................................1sec

LBO Output Sink Current ....................................................50mA

LBO Output Voltage ...............................................GND to VOUT

SHDN Input Voltage ....................................-0.3V to (VIN + 0.3V)

Input Voltages LBI, SET................................-0.3V to (VIN - 1.0V)

Continuous Power Dissipation

Plastic DIP (derate 9.09mW/°C above +70°C) ............727mW

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

CERDIP (derate 8.00mW/°C above +70°C) .................640mW

Operating Temperature Ranges

MAX667C_A........................................................0°C to +70°C

MAX667E_A .....................................................-40°C to +85°C

MAX667MJA ..................................................-55°C to +125°C

Note 1: Dropout Voltage is VIN-VOUT when VOUT falls to 0.1V below its value at VIN = VOUT + 2V.

Note 2: Short-Circuit Current is pulse tested to maintain junction temperature. Short-circuit duration is limited by package dissipation.
