2 / 6 page ![]() Data Sheet G12826EJ3V0DS00 2 µµµµPC317 ABSOLUTE MAXIMUM RATINGS (TA = 25°C, unless otherwise specified.) Parameter Symbol Rating Unit Input-Output Voltage Differential VIN − VO –0.3 to +40 V Total Power Dissipation (TC = 25 °C) PT 15 Note W Operating Ambient Temperature TA –20 to +80 °C Operating Junction Temperature TJ –20 to +150 °C Storage Temperature Tstg –65 to +150 °C Thermal Resistance (junction to case) Rth (J–C) 5 °C/W Thermal Resistance (junction to ambient) Rth (J–A) 65 °C/W Note Internally limited. When operating junction temperature rise up to 150°C ( ≤200°C), the internal circuit shutdown output voltage. Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded. RECOMMENDED OPERATING CONDITIONS Parameter Symbol MIN. TYP. MAX. Unit Input-Output Voltage Differential VIN – VO 3 38.7 V Input Voltage VIN 4.3 40 V Output Voltage VO 1.3 30 V Output Current IO 0.01 1.5 A Operating Junction Temperature TJ –20 +125 °C Caution The recommended operating range may be exceeded without causing any problems provided that the absolute maximum ratings are not exceeded. However, if the device is operated in a way that exceeds the recommended operating conditions, the margin between the actual conditions of use and the absolute maximum ratings is small, and therefore thorough evaluation is necessary. The recommended operating conditions do not imply that the device can be used with all values at their maximum values. |
