Overview
The LD6836CX4/27P,315 is a fixed positive Low DropOut regulator from the NXP LD6836 series. It provides a nominal output voltage of 2.7 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 utilizes a WLCSP4 package with dimensions of 0.76 mm x 0.76 mm x 0.47 mm and a 0.4 mm pitch. The component includes over-temperature protection, output current limiting, and integrated ESD protection up to 10 kV HBM.
Feature Summary
- Features an auto discharge function via a pull-down switching transistor for low-ohmic output state when disabled
- Provides ultra-low dropout performance with minimal power consumption during operation
- Includes integrated electrostatic discharge protection rated up to 10 kV Human Body Model
- Offers high accuracy in maintaining nominal output voltage under varying line and load conditions
Applications
- Analog and digital interfaces requiring lower supply voltages in mobile appliances
- Smartphones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players

Selection Notes
Select this variant for applications requiring a precise 2.7 V fixed output. Ensure the design accommodates the WLCSP4 package size constraints. Verify that the external capacitor meets the minimum 0.7 uF requirement for stability. Confirm that the system input voltage remains within the 2.3 V to 5.5 V operating range.
Part Context
This component belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series offers various fixed output voltages between 1.2 V and 3.6 V. The CX4 designation indicates the Wafer-Level Chip-Scale Package format, which supports component miniaturization for portable electronics.
Replacement Considerations
Compatible substitutes include other LD6836CX4 variants with different output voltages or the LD6836TD series in SOT753 packages. Verify pin compatibility and output voltage requirements before substitution.
