Datasheet LMR1901YG-M (Rohm) - 3

LMR1901YG-M Absolute Maximum Ratings (Ta = 25 °C)
Parameter Symbol Rating Unit Supply Voltage (VDD - VSS) VS 7.0 V Input Pin Voltage (+IN, -IN) VI (VSS - 0.3) to (VDD + 0.3) V Input Pin Current (+IN, -IN) II ±10 mA Maximum Junction Temperature Tjmax 150 °C Storage Temperature Range Tstg -55 to +150 °C
Caution 1:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operate over the absolute maximum ratings.
Caution 2:
Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating.
