Overview
The LD6836CX4/22H,315 is a fixed-output Low DropOut regulator from the NXP LD6836 series. It provides a nominal output voltage of 2.2 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. In disabled mode, the 'H' suffix indicates a high-ohmic (3-state) output state.
Feature Summary
- Ultra low dropout performance with minimal power loss
- High noise suppression capability for sensitive analog circuits
- Integrated thermal protection and output current limiting
- Compact wafer-level chip-scale packaging for space-constrained designs
Applications
- Analog and digital interfaces in mobile appliances
- Smartphones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the package type and output behavior. Ensure compatibility with required PCB layout guidelines for WLCSP packages. Confirm RoHS compliance status through manufacturer datasheets before integration into production environments.
Selection Notes
Select this component when a stable 2.2 V supply is required for portable electronics. The high-ohmic output state upon disablement distinguishes it from pull-down variants. Consider the small footprint and low quiescent current benefits for battery-operated applications requiring efficient power management.
Part Context
This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series includes various output voltages and package options, such as SOT753 and WLCSP4. The CX4 designation specifically refers to the wafer-level chip-scale package variant designed for miniaturization.
Replacement Considerations
LD6836CX4/22P: Identical electrical specifications but features a pull-down switching transistor for auto discharge instead of a high-ohmic state.
