Overview
The LD6836TD/22P,125 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 2.2 V with a maximum continuous output current rating of 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 90 mV at full load. It utilizes a small SOT753 surface-mounted plastic package. The component includes integrated over-temperature protection, output current limiting, and ESD protection up to 10 kV Human Body Model.
Feature Summary
- Integrated pull-down switching transistor for low-ohmic output state in disabled mode
- Ultra-low noise performance with typical RMS output noise of 30 µV
- High power supply rejection ratio of 55 dB at 1 kHz frequency
- RoHS compliant and free of halogen and antimony
Applications
- Analog and digital interfaces requiring lower than standard supply voltages
- Mobile appliances such as smartphones and cordless telephones
- Digital still cameras and portable media players
- Personal navigation devices and mobile internet devices
Procurement Notes
Verify the specific suffix '125' against official manufacturer documentation to confirm tape-and-reel packaging specifications or lot traceability details. Confirm that the SOT753 package variant matches the required footprint for the target PCB design. Ensure compatibility with the 2.2 V fixed output requirement for the intended circuit application.
Selection Notes
Select this component when a compact LDO solution is required for portable electronics. The SOT753 package offers space efficiency compared to larger packages. The pull-down feature ensures rapid discharge of output capacitance upon shutdown, which is beneficial for power management sequences. Verify that the input voltage remains within the 2.3 V to 5.5 V operational window.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series includes variants in WLCSP4 and SOT753 packages with various fixed output voltages ranging from 1.2 V to 3.6 V. The LD6836TD specifically denotes the SOT753 package version, while the '/22P' indicates the 2.2 V output voltage with the pull-down output configuration.
Replacement Considerations
Compatible substitutes include other parts from the LD6836 family with matching output voltages and package types, such as LD6836TD/22H for high-ohmic output or LD6836CX4/22P for WLCSP4 packaging. Cross-family replacements require verification of pinout compatibility and electrical parameter alignment.
