Overview
The LD6836TD/36P,125 is a Low Dropout regulator (LDO) from the LD6836 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 3.6 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 is housed in a small SOT753 Surface-Mounted Device plastic package.
Feature Summary
- Includes an integrated pull-down switching transistor that provides a low-ohmic output state when disabled, functioning as an auto discharge mechanism.
- Features over-temperature protection and output current limiting for enhanced operational safety.
- Offers low quiescent current in shutdown mode and low RMS output noise voltage.
- Incorporates integrated ElectroStatic Discharge (ESD) protection up to 10 kV Human Body Model.
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 'P' indicates the pull-down output configuration with auto discharge functionality. Confirm the 'TD' designation corresponds to the SOT753 package type. Ensure the ordering code matches the required 3.6 V fixed output voltage specification. Cross-reference the manufacturer's official documentation to validate RoHS compliance and halogen-free status before procurement.
Selection Notes
Select this component when a fixed 3.6 V rail is required within a 2.3 V to 5.5 V input window. The pull-down feature is critical if rapid output discharge is necessary upon disablement. Consider the SOT753 package size constraints and the need for external capacitors between 0.7 µF and 1.0 µF to ensure stability under varying load conditions.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators designed for portable applications. The series includes variants in WLCSP4 and SOT753 packages with various fixed output voltages ranging from 1.2 V to 3.6 V. The 'P' suffix distinguishes it from 'H' versions by providing an active pull-down rather than a high-impedance state when disabled.
Replacement Considerations
LD6836TD/36H,125: Provides the same electrical specifications but lacks the auto-discharge pull-down function, resulting in a high-ohmic output state when disabled.
