Overview
The LD6806TD/28H,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 2.8 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 characteristics, low quiescent current in shutdown mode, and integrated thermal protection and current limiting circuits.
Feature Summary
- High-ohmic (three-state) output state when disabled
- Integrated temperature watchdog for thermal protection
- Low noise performance suitable for sensitive analog interfaces
- Active HIGH enable pin for power management control
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices requiring component miniaturization
Procurement Notes
Verify that the suffix 'H' confirms the high-ohmic output state requirement for your specific circuit design. Ensure the selected package variant matches the PCB footprint specifications provided in the datasheet. Confirm RoHS compliance status if required by local regulations.
Selection Notes
Select this part when a fixed 2.8 V rail is needed with minimal board space. The SOT753 package offers a gull-wing configuration for standard surface mounting. Consider the low quiescent current benefits for battery-operated applications requiring efficient shutdown states.
Part Context
This component belongs to the LD6806 series of ultra low-dropout regulators designed for mobile appliances. The series includes variants with different output voltages and package types, such as WLCSP4 and SOT886, all sharing the same monolithic silicon regulator design architecture.
