Overview
The LD6836CX4/20P,315 is a fixed positive Low DropOut regulator with a nominal output voltage of 2.0 V. It operates within an input voltage range of 2.3 V to 5.5 V and supports a maximum output current of 300 mA. The device features a typical dropout voltage of 90 mV at full load and includes an integrated pull-down switching transistor for auto discharge functionality in shutdown mode. Packaged in a 0.76 mm x 0.76 mm WLCSP-4 with 0.4 mm pitch, it provides over-temperature protection, output current limiting, and ESD protection up to 10 kV HBM.
Feature Summary
- Ultra-low dropout performance with a typical voltage drop of 90 mV at 300 mA output rating
- Integrated pull-down switching transistor providing a low-ohmic output state during disabled mode
- Low quiescent current consumption in shutdown mode, typically 0.1 µA
- High noise immunity with a typical RMS output noise voltage of 30 µV across the 10 Hz to 100 kHz frequency band
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 '315' against official NXP documentation to confirm reel packaging specifications. Confirm RoHS compliance status and halogen-free characteristics as stated in the datasheet. Ensure the component matches the WLCSP-4 package dimensions and pinout configuration required by the design. Validate that the 2.0 V fixed output aligns with system power requirements.
Selection Notes
Select this component when miniaturization is critical due to its small WLCSP footprint. Choose the 'P' variant specifically if an auto-discharge function is required to rapidly reduce output voltage upon shutdown. Ensure the application input voltage remains within the 2.3 V to 5.5 V operating range. Verify that the external capacitor meets the minimum capacitance and ESR requirements for stability.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators manufactured using monolithic silicon technology. The series offers fixed output voltages ranging from 1.2 V to 3.6 V. The CX4 designation indicates the Wafer-Level Chip-Scale Package format, which is distinct from the SOT753 plastic package variants available in the same family.
Replacement Considerations
LD6836CX4/20H: Identical electrical performance but features a high-ohmic (3-state) output instead of auto discharge.
FAQ
What is the behavior of the output pin when the enable signal is low?
The LD6836CX4/20P contains a pull-down switching transistor that provides a low-ohmic output state, actively discharging the output voltage.
How does the LD6836CX4/20P handle electrostatic discharge?
The device integrates ElectroStatic Discharge (ESD) protection rated up to 10 kV according to the Human Body Model (HBM).
