Overview
The LD6816CX4/C12P,315 is a linear voltage regulator IC from Nexperia USA Inc., classified as a positive fixed LDO with one output. It delivers a maximum output current of 150mA and provides a fixed output voltage of 1.2V. The device supports an input voltage up to 5.5V and features a maximum dropout voltage of 0.075V. It is housed in a compact 4-WLCSP package measuring 0.76x0.76mm.
Feature Summary
- Provides a stable fixed output voltage for sensitive circuitry
- Operates with low dropout voltage for efficient power management
- Supports high output current within a small footprint
Applications
- Portable electronic devices requiring low noise power
- Battery-powered systems needing efficient voltage regulation
- Embedded circuits utilizing fixed voltage rails
Procurement Notes
Verify the complete part number including suffixes such as C12P and reel quantity indicators like ,315 against official Nexperia documentation. Confirm RoHS compliance status and lead-free specifications directly with authorized distributors or the manufacturer to ensure alignment with project requirements and regulatory standards.
Selection Notes
Select this component when a fixed 1.2V rail is required with minimal voltage drop under load. Ensure the input voltage does not exceed 5.5V and that the thermal performance of the WLCSP package suits the application environment. Compare against other LDOs if higher current or adjustable output is needed.
Part Context
This part belongs to the LD6816 series of low-dropout regulators designed for space-constrained applications. The CX4 designation indicates the specific package type, while C12P specifies the fixed output voltage variant. The series is intended for general-purpose voltage regulation in consumer electronics and portable devices.
Replacement Considerations
Check for direct substitutes within the LD6816 family offering different fixed voltages or currents. Verify pin compatibility and package dimensions before replacing with other manufacturers' LDOs to ensure mechanical and electrical fit without redesigning the PCB layout.
