Overview
The LD6816CX4/12H,315 is a fixed-output Low Dropout (LDO) regulator from NXP Semiconductors with a nominal output voltage of 1.2 V. It operates within an input voltage range of 2.3 V to 5.5 V and supports a maximum output current of 150 mA. The device features a typical dropout voltage of 45 mV at full load and includes over-temperature protection and output current limiting. It utilizes a WLCSP4 package with a 0.4 mm pitch.
Feature Summary
- High-ohmic (three-state) output state when disabled
- Ultra-low dropout voltage for efficiency maximization
- Low quiescent current in shutdown mode
- Integrated ESD protection up to 10 kV Human Body Model
Applications
- Smart phones
- Mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component for portable applications requiring miniaturization and low noise. Ensure the external load capacitor meets the minimum capacitance requirement of 0.7 µF with appropriate ESR for stability. Confirm that the high-ohmic output behavior upon disablement aligns with system requirements, as other variants offer auto-discharge functions.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series is designed for mobile appliances requiring lower than standard supply voltages. The 'H' suffix specifically denotes the high-ohmic output configuration, distinguishing it from 'P' or 'CxxP' variants which include pull-down transistors.

FAQ
What is the output state of the LD6816CX4/12H when the enable pin is low?
When the enable pin is low, the LD6816CX4/12H enters a high-ohmic (three-state) state at the output pin.
Does the LD6816CX4/12H have an auto-discharge function?
No, the LD6816CX4/12H does not have an auto-discharge function. This feature is available only in the LD6816CX4/xxP and LD6816CX4/CxxP devices.
