Overview
The LD6805K/18H,115 is a low-dropout regulator (LDO) from the LD6805 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 1.8 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 offers high power supply rejection ratio (PSRR) performance of 75 dB at 1 kHz and includes integrated over-current protection. The component utilizes a DFN1010C-4 plastic package.
Feature Summary
- Provides a fixed 1.8 V output with a 150 mA current capability
- Features ultra-high power supply rejection ratio for noise suppression
- Maintains stable regulation with minimal voltage drop under load
- Includes integrated over-current protection circuitry
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 the specific ordering suffix '115' against official documentation to confirm packaging details, as datasheets may not explicitly define this suffix's physical attributes. Confirm that the 'H' designation corresponds to the high-ohmic disabled state rather than the pull-down variant. Ensure compatibility with required PCB thermal layouts for the specified package type.
Selection Notes
Select this component when a compact LDO with high PSRR is needed for portable electronics. The 1.8 V output suits specific logic levels or analog reference requirements. Consider the high-ohmic disabled state if system isolation is preferred over auto-discharge. Verify that the 150 mA current rating meets the peak load demands of the target application circuit.
Part Context
This part belongs to the LD6805 series of low-dropout regulators designed for miniaturized applications. The series is characterized by its small DFN1010C-4 package size and monolithic silicon technology construction. It is intended for consumer electronics where space constraints and power efficiency are critical design factors.
Replacement Considerations
Consult official NXP documentation for direct substitutes. The LD6805K/18P,115 is a related variant offering a low-ohmic disabled state instead of the high-ohmic state found in the H version.
