Overview
The LD6836TD/30P,125 is a fixed-output Low Dropout regulator in an SOT753 package. It provides a nominal output voltage of 3.0 V with a maximum 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 includes an integrated pull-down switching transistor for auto discharge functionality when disabled. Key electrical characteristics include a typical quiescent current of 70 µA, RMS output noise of 30 µV, and a Power Supply Rejection Ratio of 55 dB at 1 kHz.
Feature Summary
- Integrated pull-down switching transistor provides a low-ohmic output state during shutdown for rapid auto discharge.
- Ultra-low dropout performance ensures high efficiency and minimized power consumption under varying load conditions.
- Low noise architecture delivers stable regulation suitable for sensitive analog and digital interface circuits.
- Built-in protection mechanisms include over-temperature shutdown and output current limiting.
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Smartphones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific suffix '125' against official NXP documentation to confirm reel or tape specifications, as datasheet tables list type numbers without this suffix. Confirm the SOT753 package variant matches the required pinout and marking codes. Ensure compatibility with RoHS and halogen-free compliance requirements for the target assembly process.
Selection Notes
Select this component when a fixed 3.0 V output is required with active discharge capabilities upon disable. The SOT753 package offers a compact surface-mount solution compared to WLCSP options. Consider the 300 mA current limit and 2.3 V minimum input voltage for system headroom. Verify that the external capacitor ESR meets stability requirements for the chosen operating temperature range.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series encompasses various packages including WLCSP4 and SOT753, with options for high-ohmic (H) or pull-down (P) output states. The LD6836TD specifically denotes the SOT753 plastic surface-mounted device variant designed for portable applications requiring miniaturization.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult NXP technical support for cross-reference information regarding alternative LDOs with similar pinouts and electrical characteristics.
