3 / 11 page Data Sheet G16444EJ1V0DS 3 µµµµPC37M31,37M32 RECOMMENDED OPERATING CONDITIONS Parameter Symbol MIN. TYP. MAX. Unit Input Voltage VIN 4.5 6.0 V Output Current 1 IO1 00.5 A Output Current 2 IO2 00.3 A Operating Ambient Temperature TA −40 +85 °C Operating Junction Temperature TJ −40 +125 °C Caution Use of conditions other than the above-listed recommended operating conditions is not a problem as long as the absolute maximum ratings are not exceeded. However, since the use of such conditions diminishes the margin of safety, careful evaluation is required before such conditions are used. Moreover, using the MAX. value for all the recommended operating conditions is not guaranteed to be safe.
