Overview
The LD6836TD/14P,125 is a fixed-output Low Dropout regulator (LDO) from NXP Semiconductors. It provides a nominal output voltage of 1.4 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 incorporates an auto discharge function for low-ohmic shutdown states and includes integrated over-temperature protection and output current limiting.
Feature Summary
- Features an active pull-down switching transistor that ensures a low-ohmic output state during disabled mode for rapid discharge.
- Provides ultra-low dropout performance with minimal power consumption while maintaining high accuracy in regulated output voltage.
- Includes comprehensive internal protection mechanisms against thermal overload and excessive output current conditions.
Applications
- Analog and digital interfaces requiring lower supply voltages in mobile appliances
- Powering components in smartphones and mobile phone handsets
- Supplying power to personal navigation devices and portable media players
Procurement Notes
Verify the specific suffix '125' against official manufacturer documentation to confirm packaging details and compliance status. Ensure the component matches the SOT753 package type and the 1.4 V fixed output specification required for your circuit design before procurement.
Selection Notes
Select this component when a stable 1.4 V rail is needed from a 2.3 V to 5.5 V source. The 'P' variant is suitable for applications requiring fast output discharge upon shutdown. Verify that external capacitors meet the minimum ESR requirements to ensure loop stability under all operating conditions.
Part Context
This part belongs to the LD6836 series of small-size LDO regulators manufactured using monolithic silicon technology. The series offers various fixed output voltages between 1.2 V and 3.6 V. The TD designation indicates the SOT753 surface-mounted plastic package, which is compatible with standard SOT23-5 footprints.
Replacement Considerations
Compatible substitutes include other LD6836TD variants with different output voltages or the LD6836CX4 series for WLCSP packages. Cross-reference pinouts and electrical characteristics carefully to ensure functional equivalence in existing designs.
