Overview
The LD6836CX4/28P,315 is a fixed positive Low DropOut regulator from the NXP LD6836 series. It provides a nominal output voltage of 2.8 V with an input voltage range of 2.3 V to 5.5 V. The device supports a maximum output current of 300 mA and features a typical dropout voltage of 90 mV at full load. It utilizes a WLCSP4 package with a 0.4 mm pitch and includes an integrated pull-down switching transistor for auto discharge functionality when disabled.
Feature Summary
- Integrated pull-down switching transistor providing low-ohmic output state in shutdown mode
- Ultra-low dropout performance with typical 90 mV drop at 300 mA
- Low quiescent current consumption in shutdown mode
- Built-in over-temperature protection and output current limiter
Applications
- Analog and digital interfaces requiring lower supply voltages in mobile appliances
- Smartphones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the package type and output configuration. Ensure compatibility with required PCB layout guidelines for WLCSP packages. Confirm RoHS compliance status through manufacturer datasheets before procurement.
Selection Notes
Select this component for applications requiring miniaturization due to its small WLCSP footprint. Consider the auto-discharge feature if rapid output voltage decay is necessary upon disabling. Verify that the fixed 2.8 V output meets system requirements as no adjustable variants exist within this specific part number.
Part Context
This device belongs to the LD6836 series of ultra-low dropout regulators designed for portable electronics. The series offers various output voltages and package options, including SOT753 and WLCSP formats. The CX4 variant specifically targets space-constrained designs while maintaining high efficiency and low noise characteristics.
Replacement Considerations
LD6836CX4/28H: High-ohmic output version without auto-discharge function.
