Overview
The LD6806TD/20H,125 is a low-dropout regulator (LDO) from the NXP LD6806 series, housed in an SOT753 package. It provides a fixed nominal output voltage of 2.0 V with a maximum output current rating of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and maintains a typical dropout voltage of 60 mV at full load. Key electrical characteristics include a typical quiescent current of 70 µA, an RMS output noise voltage of 30 µV over a 10 Hz to 100 kHz bandwidth, and a power supply rejection ratio of 55 dB at 1 kHz. The component features integrated thermal protection and current limiting.
Feature Summary
- Ultra-low dropout performance ensures high efficiency and minimized power consumption during operation.
- Low noise architecture delivers stable regulation suitable for sensitive analog and digital interfaces.
- Integrated enable pin allows for precise control of device activation and shutdown states.
- Built-in thermal protection and current limiting safeguard against overload conditions.
Applications
- Mobile phone handsets requiring miniaturized power solutions
- Cordless telephones needing efficient voltage regulation
- Personal digital devices utilizing lower than standard supply voltages
Procurement Notes
Verify that the ordering suffix 'H' corresponds to the high-ohmic (three-state) output configuration as specified in the datasheet. Confirm the package type matches the SOT753 designation. Ensure compatibility with RoHS compliance standards and verify the specific output voltage tolerance requirements for your design before procurement.
Selection Notes
Select this component when a compact LDO with a fixed 2.0 V output is required for space-constrained designs. Consider the SOT753 package for surface-mount applications where leaded packages are unsuitable. Evaluate the need for a high-impedance output state upon disablement, which distinguishes the 'H' variant from the low-ohmic 'P' version.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators designed for component miniaturization. The series includes variants in WLCSP4, SOT886, and SOT753 packages. The LD6806TD/20H,125 specifically utilizes the SOT753 plastic surface-mounted package, offering a balance between size and thermal performance compared to smaller chip-scale options.
Replacement Considerations
Direct substitutes within the same family include other LD6806 variants with different output voltages or package types, such as LD6806TD/25H,125 for a 2.5 V output. Cross-manufacturer replacements like the TLV705 or LP2989AIM-33 may be considered but require verification of pinout compatibility and electrical parameter alignment.
