Overview
The LD6816CX4/30H,315 is a fixed-output Low DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 3.0 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 dimensions of 0.76 mm x 0.76 mm. Key electrical characteristics include a quiescent current of 0.1 µA in shutdown mode, 30 µV RMS output noise (10 Hz to 100 kHz), and 55 dB PSRR at 1 kHz.
Feature Summary
- Ultra-low dropout performance ensures high efficiency and minimized power consumption during operation.
- Low noise architecture delivers stable power for sensitive analog and digital interfaces.
- High-ohmic output state when disabled prevents unintended current flow in the circuit.
Applications
- Smart phones
- Mobile phone handsets
- Cordless telephones
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer or authorized distributors before procurement.
Selection Notes
Select this component for portable applications requiring miniaturization due to its small WLCSP footprint. Ensure the required output voltage matches the fixed 3.0 V specification. Verify that the system input voltage remains within the 2.3 V to 5.5 V operating range.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators designed for mobile appliances. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'H' designation indicates a high-ohmic output state upon disable, distinguishing it from 'P' variants which feature auto-discharge functions.

FAQ
What is the output state of the LD6816CX4/30H when the enable pin is low?
When disabled, the LD6816CX4/30H exhibits a high-ohmic state at the output pin.
Does the LD6816CX4/30H include an auto-discharge function?
No, the 'H' variant does not contain a pull-down switching transistor for auto-discharge; this feature is available in 'P' and 'CxxP' variants.
