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

What is the function of the 'B' suffix in the model number?

The 'B' suffix indicates that the device includes an auto-discharge function which quickly lowers the output voltage to 0 V when the chip enable signal is switched to standby mode.

Can this regulator operate with ceramic output capacitors?

Yes, the RP154x series is designed to be compatible with ceramic capacitors, requiring a capacitance of 1.0 µF or more for stable operation.
