Overview
The LD6816CX4/13H,315 is a fixed-output Low DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 1.3 V with a maximum output current rating of 150 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 45 mV at full load. It utilizes a WLCSP4 package with a 0.4 mm pitch and measures 0.76 mm by 0.76 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 ensures high efficiency and minimized power consumption during operation.
- Low noise characteristics provide stable power delivery for sensitive analog and digital interfaces.
- High-ohmic (three-state) output state when disabled prevents unintended loading on the circuit.
- Integrated thermal and current protection mechanisms safeguard the device under fault conditions.
Applications
- Smart phones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Mobile internet devices
- Portable media players
Procurement Notes
Verify the specific suffix 'H' indicates the high-ohmic output configuration rather than the pull-down variant. Confirm the package type matches the required board layout constraints for the WLCSP4 footprint. Ensure the ordering code aligns with the desired 1.3 V nominal output specification before finalizing procurement.
Selection Notes
Select this component for applications requiring precise 1.3 V regulation in space-constrained portable designs. The high-ohmic output mode is suitable for systems where the output must remain floating when disabled. Verify that the external capacitor meets the minimum capacitance and ESR requirements to ensure stability across the operating temperature range.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators designed for miniaturization. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'CX4' designation identifies the Wafer-Level Chip-Scale Package format, which supports high-density surface-mount assembly in modern electronic devices.
Replacement Considerations
LD6816CX4/13P: Features a low-ohmic auto-discharge function instead of a high-ohmic state when disabled.
FAQ
What is the output state of the LD6816CX4/13H when the enable pin is low?
When disabled, the LD6816CX4/13H exhibits a high-ohmic (three-state) output state at the output pin.
Does the LD6816CX4/13H include an auto-discharge function?
No, the 'H' suffix indicates a high-ohmic output. Auto-discharge functionality is available only in the 'P' and 'CxxP' variants.
