LD6836CX4/C33P,315

Overview

The LD6836CX4/C33P,315 is a positive fixed linear voltage regulator IC manufactured by Nexperia USA Inc. It provides a single output of 3.3V with a maximum load current of 300mA. The device features a low dropout voltage of 0.16V and includes protection against over-current and over-temperature conditions. It operates within a supply voltage range up to 6V and draws a maximum supply current of 250µA. Packaged in a compact 4-WLCSP (0.76x0.76mm) format, it is designed for space-constrained applications requiring efficient power management.

Feature Summary

• Provides a stable 3.3V fixed output voltage with high accuracy
• Supports up to 300mA load current with minimal voltage drop
• Integrates over-current and over-temperature protection mechanisms
• Utilizes ultra-small 4-WLCSP packaging for board space efficiency

Applications

• Portable consumer electronics requiring low-power regulation
• Battery-powered devices needing efficient voltage conversion
• Embedded systems with strict space constraints
• IoT modules requiring stable 3.3V logic supplies

Procurement Notes

Verify the complete part number including suffix ,315 to ensure correct tape-and-reel packaging configuration. Confirm that the 3.3V output variant matches system requirements, as other voltage options exist within the LD6836 family. Check for RoHS compliance documentation if required by specific regional regulations. Ensure ESD handling procedures are followed due to the small WLCSP package size.

Selection Notes

Select this component when a fixed 3.3V output is required with moderate current capability. Consider the 0.16V dropout characteristic for applications operating near minimum input voltages. Evaluate the 250µA quiescent current impact on battery life. Compare thermal performance in the WLCSP package against alternative packages if high ambient temperatures are expected.

Part Context

This part belongs to the LD6836 series of low-dropout linear regulators from Nexperia. The series offers multiple fixed output voltages and current ratings. The CX4 designation indicates the specific pinout and package type. The C33P suffix specifies the 3.3V output version. This series is designed for portable applications where efficiency and size are critical factors.

Replacement Considerations

Direct substitutes include other LD6836 variants with different output voltages if voltage adjustment is acceptable. Cross-reference with similar 3.3V LDOs in 4-WLCSP packages from other manufacturers, ensuring pin compatibility and electrical specifications match. Verify thermal resistance values for equivalent heat dissipation capabilities.
