ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(Circuit of Figure 1, capacitors from Table 2, VIN = +5V, SHDN = IN, TA = -40°C to +85°C, 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.

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

C1+, SHDN to GND .....................................-0.3V to (VIN + 0.3V)

C1- to GND...............................................(VOUT - 0.3V) to +0.3V

OUT to GND .............................................................+0.3V to -6V

OUT Short-Circuit to GND ..............................................1 minute

Continuous Power Dissipation (TA = +70°C)

6-Pin SC70 (derate 3.1mW/°C above +70°C) .............245mW

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

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

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

Note 1: All devices are 100% production tested at TA = +25

°C. All temperature limits are guaranteed by design.

Note 2: Output resistance is guaranteed with capacitor ESR of 0.3

Ω or less.
