Overview
The LD6836CX4/36P,315 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6836 series. It provides a nominal output voltage of 3.6 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. Packaged in a 0.4 mm pitch Wafer-Level Chip-Scale Package (WLCSP4), it includes an integrated pull-down switching transistor for auto discharge functionality when disabled.
Feature Summary
- Integrates a pull-down switching transistor to provide a low-ohmic output state upon deactivation.
- Delivers high power supply rejection ratio performance to suppress input noise and ripples.
- Incorporates over-temperature protection and output current limiting mechanisms.
- Features built-in electrostatic discharge protection rated up to 10 kV Human Body Model.
Applications
- Analog and digital interfaces requiring lower than standard supply voltages
- Mobile appliances such as smartphones and mobile phone handsets
- Cordless telephones and personal navigation devices
- Digital still cameras and portable media players
Procurement Notes
Verify that the specific ordering suffix matches the required package variant and output configuration. Confirm the nominal output voltage aligns with system requirements. Ensure compliance with environmental standards such as RoHS and REACH restrictions. Check datasheet specifications for thermal resistance and capacitor values to guarantee stable operation under intended load conditions.
Selection Notes
Select this component for applications necessitating compact form factors due to its WLCSP4 packaging. Choose this part when an active pull-down function is required to rapidly discharge output capacitance during shutdown. Consider the device for designs operating with limited input voltage headroom given its ultra-low dropout characteristics.
Part Context
This component belongs to the LD6836 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. Devices are available in both WLCSP and SOT753 packages, catering to different space constraints and thermal management needs within portable electronic systems.
