Overview
The LD6836CX4/16P,315 is a fixed positive Low DropOut (LDO) regulator from the NXP LD6836 series. It provides a nominal output voltage of 1.6 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. The component includes over-temperature protection, output current limiting, and integrated ESD protection up to 10 kV HBM.
Feature Summary
- Ultra-low dropout performance with low quiescent current in shutdown mode
- Low noise operation suitable for sensitive analog and digital interfaces
- Integrated pull-down switching transistor for auto discharge function when disabled
- High electrostatic discharge protection capability
Applications
- Smartphones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this variant for designs requiring a precise 1.6 V supply rail in space-constrained portable electronics. The WLCSP4 package minimizes board footprint while maintaining thermal efficiency. Ensure external capacitors meet the minimum 0.7 µF requirement with appropriate ESR characteristics to guarantee stability across the operating temperature 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 'P' suffix indicates the presence of an internal pull-down transistor for output discharge, distinguishing it from 'H' variants which present a high-ohmic state when disabled.
Replacement Considerations
Compatible substitutes include other LD6836CX4 variants with different output voltages or the LD6836TD series in SOT753 packaging. Verify pin compatibility and electrical specifications before substitution.
