The LM2931AD-5.0R2G with LDO Voltage Regulators 5V 100mA w/Load Dump is a load dump protected, low dropout, low quiescent current, three-terminal adjustable LM2931 linear voltage regulator manufactured by ON Semiconductor. It has a fixed 5V output with a maximum output current of 100mA and works in a device-supplied input voltage range of 6V to Ultralow Dropout Voltage. It also features a wide range of protection features, including inrush current limiting, thermal shutdown, reverse-battery protection, and load-dump protection for load dump spikes up to 45V. The robust design makes it suitable for automotive applications in harsh conditions.
