IXD1421AB51ER-G

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

The IXD1421AB51ER-G is a dual low-dropout (LDO) voltage regulator manufactured by Zilog. It provides two independent positive fixed output channels, each capable of delivering up to 300mA of current. The device is housed in a compact 6-USPC package with dimensions of 1.8x2 mm. Classified under PMIC - Power Management ICs, it is designed for applications requiring small form factor and high-speed regulation capabilities.

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

Verify the manufacturer origin carefully, as Zilog has been acquired by IXYS and subsequently Littelfuse. Confirm that the specific suffix matches the required output voltage configuration. Ensure compatibility with the intended PCB layout given the small USPC package size. Check for updated datasheets reflecting any post-acquisition revisions or testing standards.

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

Select this component when a dual LDO solution is required within a minimal area constraint. The 300mA per channel rating suits moderate load applications. Consider the fixed output voltage determined by the model suffix during initial design phases. Evaluate thermal performance requirements based on the small surface mount package limitations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the IXD14xx series of dual high-speed LDO regulators from Zilog. The series is characterized by its ability to provide stable regulation in compact packages. The AB51 suffix typically denotes specific fixed output voltages for the dual channels, distinguishing it from other variants in the family with different electrical specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes may include other dual LDOs in 6-pin SOT-363 or similar tiny packages from manufacturers like TI or ST. Verify pin-to-pin compatibility and output voltage matching before substitution. Cross-reference with IXYS/Littelfuse portfolios for equivalent parts if Zilog stock is unavailable.
