Overview
The LD6806TD/29H,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 2.9 V with a maximum continuous output current of 200 mA and peak capability up to 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V. It features ultra-low dropout performance, typically 60 mV at 200 mA, and low quiescent current of 1.0 µA in shutdown mode. The component includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.
Feature Summary
- Ultra-low dropout voltage ensures high efficiency and minimized power consumption during operation.
- Low noise output characteristic suitable for sensitive analog and digital interface applications.
- Integrated thermal watchdog and current limiter provide robust protection against overload conditions.
- High-ohmic (three-state) output state when disabled, isolating the load from the supply.
Applications
- Mobile phone handsets requiring component miniaturization
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix 'H' indicates the high-ohmic output configuration distinct from the 'P' variant. Confirm the package designation corresponds to SOT753 (TSOP5). Ensure environmental compliance requirements match the dark green compliant specification regarding halogen and antimony content.
Selection Notes
Select this part for designs requiring a precise 2.9 V rail from a variable 2.3 V to 5.5 V source. The SOT753 package offers a gull-wing surface-mount form factor suitable for standard PCB assembly. Consider the external capacitor requirements for stability and the specific enable pin logic levels for system control integration.
Part Context
This component belongs to the LD6806 series of small-size Low-DropOut regulators manufactured using monolithic silicon technology. The series supports multiple output voltages ranging from 1.2 V to 3.6 V and is available in various surface-mounted packages including WLCSP4, SOT886, and SOT753.

FAQ
What is the output state of the LD6806TD/29H when the enable pin is low?
The device enters a high-ohmic (three-state) state at the output pin, effectively disconnecting the regulator output.
Does the LD6806TD/29H require an external capacitor for stability?
Yes, an external load capacitance of at least 1.0 µF is required to guarantee stable regulator behavior.
