- Low-power embedded circuits
Procurement Notes
Verify the exact part number suffix and manufacturer origin when sourcing. Confirm that the received components match the specified 2.9V output and 150mA rating. Ensure the packaging type corresponds to the 4-WLCSP format. Check for compliance with relevant environmental standards such as RoHS if required by your specific application regulations.
Selection Notes
Select this component when a precise 2.9V fixed output is required from a linear regulator. Consider the 150mA current limit to ensure it meets the load requirements of the target circuit. The small WLCSP footprint makes it suitable for space-constrained designs. Evaluate thermal performance based on the expected power dissipation within the limited package size.
Part Context
This part is categorized under Voltage Regulators - Linear, Low Drop Out (LDO) Regulators within the Nexperia portfolio. It serves as a Power Management IC (PMIC) solution for providing stable voltage rails. The product line focuses on efficient power delivery for modern electronic systems requiring compact form factors and reliable regulation characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts and electrical specifications before considering alternative components from other manufacturers.
