SNOSDC0A October 2020 – December 2020 LM7310
The LM73100 devices are designed for a supply voltage range of 2.7 V ≤ VIN ≤ 23 V. An input ceramic bypass capacitor higher than 0.1 μF is recommended if the input supply is located more than a few inches from the device. The power supply must be rated higher than the set current limit to avoid voltage droops during overcurrent and short-circuit conditions.
The maximum negative voltage the device can handle at the input is limited to -15 V or VOUT – 21 V, whichever is higher. Any low voltage signals (e.g. EN/UVLO, OVLO, PGTH) derived from the input supply must have a sufficiently large pull-up resistor to limit the current through those pins to < 10 μA during reverse polarity conditions. Please refer to Absolute Maximum Ratings table for more details.
