LD6836CX4/33H,315

Overview

The LD6836CX4/33H,315 is a fixed positive Low Dropout (LDO) regulator providing a nominal output voltage of 3.3 V. It operates within an input voltage range of 2.3 V to 5.5 V and supports a maximum output current of 300 mA. The device features a typical dropout voltage of 90 mV at full load and includes over-temperature protection and output current limiting. It utilizes a WLCSP4 package with a 0.4 mm pitch.

Feature Summary

• Provides high-ohmic (three-state) output when disabled
• Features integrated electrostatic discharge protection up to 10 kV Human Body Model
• Includes over-temperature protection and output current limiter

Applications

• Analog and digital interfaces in mobile appliances
• Smartphones and mobile phone handsets
• Cordless telephones
• Digital still cameras
• Portable media players

Procurement Notes

Verify the specific suffix '315' against official NXP documentation to confirm tape-and-reel specifications or marking codes. Ensure the component matches the WLCSP4 package dimensions and pinout configuration for your PCB layout. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this part for applications requiring a compact footprint and low quiescent current. The high-ohmic output state is suitable for bus-sharing scenarios where a high-impedance state is needed during shutdown. Ensure external capacitors meet the minimum ESR requirements for stability.

Part Context

This component belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'H' suffix indicates the high-ohmic output variant, distinguishing it from the pull-down 'P' version which includes an auto-discharge function.

Replacement Considerations

LD6836CX4/33P provides similar regulation but with a pull-down output state instead of high-ohmic.
