LD6836TD/13H,125

Overview

The LD6836TD/13H,125 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 1.3 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. Packaged in the small SOT753 surface-mount format, it includes integrated over-temperature protection, output current limiting, and high-ohmic disabled state characteristics.

Feature Summary

• Ultra-low dropout performance ensuring efficient power regulation under varying load conditions
• Low noise operation suitable for sensitive analog and digital interface circuits
• Integrated safety mechanisms including thermal shutdown and output current limiting
• High-ohmic output state when disabled, preventing unintended load discharge

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and output configuration. Ensure compatibility with the required PCB footprint for the SOT753 package. Confirm that the fixed 1.3 V output aligns with the target circuit design requirements before procurement.

Selection Notes

Select this component for applications requiring a compact LDO with low quiescent current and minimal noise. The SOT753 package is ideal for space-constrained designs. Verify that the input voltage remains within the specified 2.3 V to 5.5 V range and that the load does not exceed the 300 mA current rating.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series offers various fixed output voltages and packaging options, including WLCSP and SOT753. The LD6836TD variant specifically utilizes the SOT753 plastic surface-mounted device package, providing a balance between size and thermal performance.

Replacement Considerations

Consult the official datasheet for compatible alternatives within the LD6836 family or other NXP LDOs. Verify pinout compatibility and electrical specifications such as output voltage tolerance and current ratings before substituting.
