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

Does the NCP606MN50T2G require a minimum load current for proper regulation?

Unlike some other regulators, the NCP605/606 fixed voltage versions have no limitation for minimum load current and can operate properly under no-load conditions.

What is the function of the SENSE/ADJ pin in the fixed version?

In the fixed voltage version, the SENSE/ADJ pin should be connected directly to the output capacitor to monitor the regulated output voltage.
