LD6836CX4/14H,315

Overview

The LD6836CX4/14H,315 is a fixed-output Low DropOut regulator from the NXP LD6836 series. It provides a nominal output voltage of 1.4 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. In disabled mode, the 'H' suffix indicates a high-ohmic (3-state) output state.

Feature Summary

Ultra-low dropout performance with minimal voltage loss at high currents
High-ohmic output state when disabled for efficient power management
Integrated over-temperature protection and output current limiting
Low quiescent current in shutdown mode

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

Procurement Notes

Verify the specific ordering suffix ',315' against official manufacturer documentation to confirm reel packaging specifications. Confirm that the 'H' designation strictly corresponds to the high-ohmic output state as defined in the datasheet. Ensure compatibility with the required 1.4 V fixed output voltage for the target circuit design.

Selection Notes

Select this component when a compact footprint is required due to its WLCSP4 package size. Choose the 'H' variant if a high-impedance output state is necessary during disable periods rather than an auto-discharge function. Ensure the application input voltage remains within the 2.3 V to 5.5 V operating range for stable regulation.

Part Context

This part belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series includes variants in WLCSP4 and SOT753 packages with various fixed output voltages ranging from 1.2 V to 3.6 V. The CX4 suffix specifically denotes the Wafer-Level Chip-Scale Package configuration.
