Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the maximum input voltage for continuous operation?

The maximum operational input voltage is 40V. While the device can survive voltages up to 55V, continuous operation above 40V may cause failure due to safe operating area limitations.

Is external output capacitance required for stability?

Yes, an output bypass capacitor is required. The datasheet specifies a capacitance range with an effective series resistance (ESR) between 0.3Ω and 8Ω to ensure stability.
