Overview
The LD6836CX4/22P,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 a 0.4 mm pitch and dimensions of 0.76 mm x 0.76 mm x 0.47 mm. This variant includes an integrated pull-down switching transistor for auto discharge functionality.
Feature Summary
- Features ultra-low dropout performance with a typical voltage drop of 90 mV at 300 mA output current.
- Includes an integrated pull-down switching transistor that provides a low-ohmic output state when disabled.
- Offers low quiescent current in shutdown mode and high power supply rejection ratio for noise-sensitive applications.
- Incorporates over-temperature protection and output current limiter for enhanced system reliability.
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Smartphones, mobile phone handsets, and cordless telephones
- Digital still cameras, mobile internet devices, personal navigation devices, and portable media players
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the package type and output configuration. Ensure compatibility with the required nominal output voltage and thermal management requirements for the target application environment.
Selection Notes
Select this component for designs requiring miniaturization due to its small WLCSP footprint. Consider the auto discharge feature if rapid output voltage decay is necessary upon disable. Verify that the external capacitor ESR meets stability requirements.
Part Context
This part 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 in both WLCSP and SOT753 packages, designed for portable consumer electronics.
Replacement Considerations
LD6836CX4/22H: Same package and electrical characteristics but features a high-ohmic (3-state) output instead of the pull-down auto discharge function.
