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

What is the recommended output capacitor for the S-L2980A37MC-TF-G?

A ceramic capacitor of 1.0 µF or more with an Equivalent Series Resistance (ESR) of 10 Ω or less is recommended for phase compensation and stability.

How does the ON/OFF pin function on this specific model?

As a Type A product, setting the ON/OFF pin to a High level activates the regulator, while a Low level shuts down internal circuits to minimize current consumption.
