LD6836TD/14H,125

Overview

The LD6836TD/14H,125 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 1.4 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 small SOT753 surface-mounted plastic package.

Feature Summary

• Ultra-low dropout performance for high efficiency
• Low quiescent current in shutdown mode
• High-ohmic output state when disabled
• Integrated over-temperature protection

Applications

• Analog and digital interfaces requiring lower supply voltages
• Mobile appliances such as smartphones and cordless telephones
• Digital still cameras and portable media players

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact output voltage and package variant. Ensure compatibility with the required PCB footprint and thermal management requirements for the SOT753 package before finalizing procurement.

Selection Notes

Select this component for applications requiring a stable 1.4 V rail from a variable input source between 2.3 V and 5.5 V. Consider the high-ohmic output characteristic suitable for bus-holding or tri-state logic interfacing where low leakage is required during disable states.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series includes various output voltages and packages, including WLCSP and SOT753 options, designed for portable electronics requiring miniaturization and low power consumption.

Replacement Considerations

Consult official substitution lists for compatible LDOs with matching 1.4 V output and 300 mA capability. Verify pinout compatibility with the SOT753 package if replacing with devices from other manufacturers.
