Overview
The LD6836CX4/20H,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 utilizes a WLCSP4 package measuring 0.76 mm x 0.76 mm with a 0.4 mm pitch. Key electrical characteristics include a typical dropout voltage of 90 mV at full load, a quiescent current of 70 µA, and an RMS output noise of 30 µV over the 10 Hz to 100 kHz frequency band.
Feature Summary
- Provides high-ohmic (three-state) output when disabled
- Features integrated over-temperature protection and output current limiting
- Includes integrated ESD protection up to 10 kV Human Body Model
- Designed for ultra-low dropout operation and low noise performance
Applications
- 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 specifications or tape-and-reel packaging details. Ensure the component matches the WLCSP4 form factor and 2.0 V fixed output requirement. Confirm RoHS compliance status and lead-free manufacturing standards prior to integration into production designs.
Selection Notes
Select this variant when a compact footprint is required alongside a precise 2.0 V supply rail. The high-ohmic output state distinguishes it from pull-down versions, making it suitable for bus-sharing applications where a high-impedance state is necessary during shutdown. Evaluate thermal resistance requirements based on PCB layout constraints.
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 ranging from 1.2 V to 3.6 V in both WLCSP4 and SOT753 packages. The CX4 designation specifically identifies the wafer-level chip-scale package configuration optimized for portable electronics.
Replacement Considerations
LD6836CX4/20P provides identical electrical performance but features a pull-down auto-discharge function instead of a high-ohmic output state.
