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

What is the minimum required output capacitance for the AZ1117ID-1.5TRG1?

A minimum of 10µF output capacitor is required. The device is compatible with low ESR ceramic capacitors, provided their ESR is less than 20Ω.

How does the AZ1117ID-1.5TRG1 protect against overload conditions?

The device incorporates both current limiting and on-chip thermal shutdown. Current limiting is typically set at 1.35A, and thermal shutdown activates to prevent junction temperature from exceeding safe levels during high current or high ambient temperature scenarios.
