Overview
The LD6805K/30H,115 is a fixed-output Low DropOut regulator from the NXP LD6805 series. It provides a nominal output voltage of 3.0 V with a maximum output current rating of 150 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 250 mV at full load. It incorporates high Power Supply Rejection Ratio (PSRR) performance of 75 dB at 1 kHz and low quiescent current in shutdown mode. The component utilizes a DFN1010C-4 plastic package measuring 1 x 1 x 0.55 mm.
Feature Summary
- High PSRR capability for effective suppression of input noise and ripples
- Ultra-small DFN package optimized for portable applications requiring miniaturization
- Integrated ESD protection up to 6 kV Human Body Model level
- Auto discharge function via pull-down switching transistor in disabled mode
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Smart phones, mobile phone handsets, and cordless telephones
- Digital still cameras, mobile internet devices, personal navigation devices, and portable media players
Procurement Notes
Verify that the specific suffix '115' aligns with the manufacturer's standard packaging designation for this part number. Confirm the RoHS compliance status and halogen-free characteristics as specified in the product data sheet prior to procurement. Ensure the ordering information matches the required 3.0 V output variant within the LD6805K/xxH or xxP series.
Selection Notes
Select this component when a compact footprint is critical for portable designs. The LD6805K/30H,115 is suitable for applications needing stable power delivery under varying load conditions. Consider the auto discharge feature if rapid output voltage decay is required upon disabling. Verify that the external load capacitance meets the minimum stability requirements specified in the datasheet.
Part Context
This device belongs to the LD6805 series of low-dropout regulators manufactured by NXP Semiconductors. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. All variants share the same physical package dimensions and core electrical characteristics, differing primarily in their regulated output voltage levels and the presence or absence of the auto discharge function.
Replacement Considerations
Compatible substitutes include other LD6805 series variants such as LD6805K/33H or LD6805K/28H, provided the output voltage requirement differs. For identical 3.0 V output, consider LD6805K/30P if the auto discharge function is preferred over the high-ohmic state.
