Overview
The LD6836CX4/13H,315 is a fixed-output Low DropOut regulator from the NXP LD6836 series. It provides a nominal output voltage of 1.3 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 part includes integrated over-temperature protection, output current limiting, and ESD protection up to 10 kV HBM.
Feature Summary
- Ultra-low dropout performance with a typical voltage drop of 90 mV at 300 mA output current.
- High-ohmic (three-state) output state when disabled, suitable for bus sharing applications.
- Low quiescent current in shutdown mode, typically 0.1 µA, to minimize power consumption.
- Integrated low-noise regulation with a typical RMS output noise voltage of 30 µV.
Applications
- Analog and digital interfaces requiring lower supply voltages in mobile appliances
- Smartphones, mobile phone handsets, and cordless telephones
- Digital still cameras and portable media players
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm RoHS compliance and halogen-free status as stated in the datasheet. Ensure the high-ohmic output configuration matches system requirements for disabled states. Check for availability through authorized distributors as this component may have limited stock or be subject to obsolescence notices.
Selection Notes
Select this variant when a fixed 1.3 V rail is required with minimal footprint constraints. The WLCSP4 package offers significant size reduction compared to SOT753 alternatives. Consider the high-ohmic output behavior if multiple regulators share a common line. Ensure external capacitors meet the minimum 0.7 µF requirement for stability.
Part Context
This component belongs to the LD6836 series of ultra-low dropout regulators designed for portable electronics. The series includes variants with pull-down outputs (P suffix) and different packages like SOT753. The CX4 designation specifically indicates the Wafer-Level Chip-Scale Package format, optimized for miniaturization in space-constrained mobile devices.
Replacement Considerations
LD6836CX4/13P,315: Identical electrical characteristics but features a pull-down auto-discharge function instead of high-ohmic output.
FAQ
What is the output state of the LD6836CX4/13H when the enable pin is low?
When disabled, the LD6836CX4/13H exhibits a high-ohmic (three-state) output state at the output pin.
Does this regulator require an external capacitor for stability?
Yes, the device requires an external load capacitance of at least 0.7 µF to guarantee stable regulator behavior.
