FAQ
What type of output capacitor is recommended for stability?
The device is stable with low ESR ceramic capacitors ranging from 1µF to 4.7µF, specifically those with X7R or X5R temperature characteristics.
How does the device handle short-circuit conditions?
Short-circuit protection triggers when the output voltage drops below 200mV, clamping the output current to approximately 50mA to protect the regulator.
