Overview
The NXP LD6806TD/28P,125 is a fixed-output Low-DropOut regulator in the SOT753 package. It provides a nominal output voltage of 2.8 V with a maximum continuous current rating 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. Key electrical characteristics include a typical dropout voltage of 60 mV at 200 mA, low quiescent current of 1.0 µA in shutdown mode, and an RMS output noise voltage of 30 µV across the 10 Hz to 100 kHz bandwidth.
Feature Summary
- Features a pull-down switching transistor that ensures a low-ohmic output state when the device is disabled.
- Includes integrated thermal protection and overcurrent limiting for robust operation under fault conditions.
- Provides high power supply rejection ratio (PSRR) to suppress input voltage ripple and noise.
- Offers fast turn-on time and integrated electrostatic discharge (ESD) protection.
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Mobile phone handsets and cordless telephones
- Personal digital devices and media players
Procurement Notes
Verify the specific suffix '28P' confirms the 2.8 V fixed output and low-ohmic disabled state. Confirm the 'TD' prefix corresponds to the SOT753 plastic surface-mounted package. Ensure the '125' suffix matches the required tape and reel packaging format for automated assembly processes.
Selection Notes
Select this component when a compact LDO with a 2.8 V fixed output is required for space-constrained designs. The SOT753 package offers a small footprint suitable for dense PCB layouts. Consider the low quiescent current and low noise specifications if powering sensitive analog circuits or RF sections in battery-operated portable devices.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators manufactured by NXP Semiconductors. The series utilizes monolithic silicon technology and is designed for applications demanding component miniaturization. The LD6806 family includes variants with different output voltages and package options, such as WLCSP4 and SOT886, to support diverse design requirements.

FAQ
What is the output state of the LD6806TD/28P,125 when the enable pin is low?
When the enable pin is low, the device enters a disabled state where the internal pull-down switching transistor activates, providing a low-ohmic output stage.
Does the LD6806TD/28P,125 require an external capacitor for stability?
Yes, the device requires an external load capacitance of at least 1.0 µF to guarantee stable regulator behavior and correct operation.
