Overview
The LD6836TD/20P,125 is a Low Dropout regulator (LDO) from the LD6836 series manufactured by NXP. It provides a fixed nominal output voltage of 2.0 V with an operating input voltage range of 2.3 V to 5.5 V. The device supports a maximum output current rating of 300 mA and features a typical dropout voltage of 90 mV at full load. It utilizes a small SOT753 Surface-Mounted Device plastic package. In disabled mode, this specific variant contains a pull-down switching transistor to provide a low-ohmic output state for auto discharge functionality.
Feature Summary
- Features ultra-low dropout performance with minimal voltage drop at high current loads
- Includes integrated over-temperature protection and output current limiter
- Provides low quiescent current consumption in shutdown mode
- Offers low RMS output noise voltage for sensitive analog and digital interfaces
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Smartphones, mobile phone handsets, and cordless telephones
- Digital still cameras and portable media players
- Mobile internet devices and personal navigation devices
Procurement Notes
Verify the exact part number against official NXP documentation to confirm the 2.0 V fixed output specification and SOT753 packaging. Ensure compatibility with system requirements regarding the 2.3 V to 5.5 V input range and 300 mA output capability. Confirm that the pull-down auto-discharge function aligns with the design's power management needs during disabled states.
Selection Notes
Select this component when a compact LDO solution is required for portable applications needing a precise 2.0 V rail. Consider its low noise characteristics for powering sensitive RF or audio circuits. Evaluate the thermal resistance and PCB layout requirements to ensure adequate heat dissipation within the specified ambient temperature range.
Part Context
This device belongs to the LD6836 series of ultra-low dropout regulators designed for miniaturization. The series includes variants in WLCSP and SOT753 packages with various fixed output voltages. The TD suffix indicates the SOT753 surface-mount package, while the P suffix denotes the pull-down output configuration for rapid discharge upon shutdown.
Replacement Considerations
Consult official NXP documentation for confirmed substitute part numbers within the LD6836 family. Verify pinout compatibility and electrical specifications before replacing components.
