ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VIN = V SHDN = +5V, CIN = 10µF, COUT = 22µF, CFLY = 2.2µF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at

TA = +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.

IN ..............................................................................-0.3V to +6V

CAP+, FB, LIN/SKIP.....................................-0.3V to (VIN + 0.3V)

SHDN........................................................................-0.3V to +6V

OUT, CAP-................................................................-6V to +0.3V

Continuous Output Current ...............................................135mA

Output Short-Circuit Duration to GND (Note 1) ....................1sec

Continuous Power Dissipation (TA = +70°C)

(derate 5.88mW/°C above +70°C) ...............................450mW

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

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

Storage Temperature Range .............................-65°C to +160°C

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

Note 1: Shorting OUT to IN may damage the device and should be avoided.
