LD6836CX4/30H,315

Overview

The LD6836CX4/30H,315 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 3.0 V with a maximum output current rating of 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 90 mV at full load. It utilizes a WLCSP4 package with a 0.4 mm pitch and dimensions of 0.76 mm x 0.76 mm x 0.47 mm. In disabled mode, the 'H' suffix indicates a high-ohmic state at the output pin.

Feature Summary

• Ultra-low dropout performance with minimal voltage loss at rated current
• Low noise operation suitable for sensitive analog and digital interfaces
• Integrated over-temperature protection and output current limiting
• High-ohmic output state in shutdown mode for efficient power management

Applications

• Smartphones and mobile phone handsets
• Cordless telephones
• Digital still cameras
• Mobile internet devices
• Portable media players

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and output configuration. Ensure compatibility with required PCB layout guidelines for thermal dissipation and stability. Confirm RoHS compliance status through manufacturer datasheets prior to integration.

Selection Notes

Select this component when miniaturization is critical due to its WLCSP4 footprint. Choose the 'H' variant if a high-impedance output state is required during disable cycles. Ensure external capacitors meet minimum ESR requirements for stable regulation under varying load conditions.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators designed for portable applications. The series offers various fixed output voltages between 1.2 V and 3.6 V. The CX4 designation specifically refers to the wafer-level chip-scale package format, distinguishing it from SOT753 plastic packages available in the same family.

Replacement Considerations

LD6836CX4/30P: Identical electrical specifications but features a pull-down auto-discharge function instead of a high-ohmic state.
