Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific package type and output voltage accuracy against the datasheet specifications before procurement. Confirm that the ordering suffix corresponds to the required packaging format. Ensure compatibility with the system's input voltage range and thermal requirements. Cross-reference the part number with official manufacturer documentation to validate authenticity and revision status.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.4 V output is required with a maximum load of 200 mA. The B-series designation indicates the presence of the CL auto-discharge feature, which is necessary if rapid output discharge is required upon shutdown. Ensure the application environment stays within the -40℃ to +85℃ operating temperature range and that the input voltage does not exceed 6.0 V.

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

How does the XC6221B14AGR-G handle output discharge in standby mode?

As a B-type regulator, it utilizes an internal auto-discharge switch connected between the VOUT and VSS pins. This allows the electric charge on the output capacitor to be discharged quickly when the CE pin is set to a low level.

What is the logic level requirement for the CE pin?

The CE (Control Enable) pin operates with Active High logic. A high-level signal activates the regulator, while a low-level signal turns it off and engages the standby mode.
