Overview
The LD6806TD/12P,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 1.2 V with a maximum continuous output current of 200 mA and peak currents up to 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V. It features a typical dropout voltage of 60 mV at 200 mA and low quiescent current in shutdown mode. The component utilizes a SOT753 (TSOP5) surface-mounted package.
Feature Summary
- Low-ohmic output state when disabled via integrated pull-down switching transistor
- Ultra-low noise performance with typical RMS output noise of 30 µV
- Integrated thermal protection and current limiter for enhanced reliability
- High power supply rejection ratio ensuring stable operation under varying input conditions
Applications
- Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances
- Mobile phone handsets and personal digital devices
- Cordless telephones
Procurement Notes
Verify the specific suffix '125' against official documentation to confirm packaging details such as tape and reel specifications or RoHS compliance status. Ensure the ordering code matches the exact SOT753 package variant required for your design. Cross-reference the manufacturer's latest datasheet revision to confirm availability and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component for designs prioritizing miniaturization and low noise in portable electronics. The SOT753 package offers a compact footprint suitable for space-constrained layouts. Consider the low-ohmic output feature if active discharge of the load capacitance is required upon shutdown. Ensure the application input voltage remains within the 2.3 V to 5.5 V range for optimal regulation.
Part Context
This part belongs to the LD6806 series, a family of small-size Low-DropOut regulators designed for applications requiring component miniaturization. The series includes variants with high-ohmic outputs (suffix H) and low-ohmic outputs (suffix P). The LD6806TD/xxx designation specifically indicates the TSOP5 plastic surface-mounted package version, distinguishing it from WLCSP4 and SOT886 package options available in the same family.
Replacement Considerations
Direct substitutes within the LD6806 family include other output voltage variants in the SOT753 package, such as LD6806TD/18P,125 or LD6806TD/25P,125, provided the different fixed output voltage meets system requirements. Verify pin compatibility and electrical characteristics before substitution.
