LD6836TD/29H,125

Overview

The LD6836TD/29H,125 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 2.9 V with a maximum continuous 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 Device plastic package. In disabled mode, the 'H' variant maintains a high-ohmic state at the output pin.

Feature Summary

• Ultra low dropout performance with minimal voltage drop at rated current
• Low quiescent current consumption in shutdown mode
• Integrated over-temperature protection and output current limiter
• High-ohmic output state when disabled

Applications

• Analog and digital interfaces requiring lower than standard 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 matches the required output voltage and package type. Confirm RoHS compliance status for environmental requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity. Check datasheet revisions for any updates to electrical characteristics or application notes before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a stable 2.9 V rail from a variable input source between 2.3 V and 5.5 V. The SOT753 package is suitable for space-constrained designs. Consider the high-ohmic output behavior if bus isolation is needed during shutdown. Verify that external capacitor ESR values fall within the specified stability range to prevent oscillation.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series includes variants in WLCSP4 and SOT753 packages with various fixed output voltages ranging from 1.2 V to 3.6 V. The 'TD' designation indicates the SOT753 surface-mount package, while '29H' specifies the 2.9 V output and high-ohmic disable state.

Replacement Considerations

LD6836TD/29P,125 offers the same electrical parameters but includes an auto discharge function via a pull-down transistor in the disabled state.
