Overview
The LD6805K/22H,115 is a fixed-output Low Dropout Regulator (LDO) from the NXP LD6805 series. It provides a nominal output voltage of 2.2 V with a maximum continuous 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.
Feature Summary
- High PSRR capability for effective noise suppression
- Ultra-small DFN1010C-4 package design
- Low quiescent current operation in shutdown mode
- Integrated over-current protection
Applications
- Mobile phone handsets
- Digital still cameras
- Portable media players
- Personal navigation devices
Procurement Notes
Verify the specific suffix 'H' indicates a high-ohmic output state when disabled, distinct from the 'P' variant which includes an auto discharge function. Confirm the ordering code matches the required 2.2 V nominal output specification. Ensure compatibility with the specified DFN1010C-4 footprint and thermal requirements during procurement planning.
Selection Notes
Select this component for applications requiring precise 2.2 V regulation with minimal voltage drop under load. The high PSRR makes it suitable for sensitive analog and digital interfaces in mobile appliances. Consider the high-ohmic disabled state if external pull-down circuitry is preferred or required by the system design constraints.
Part Context
This part belongs to the LD6805 series of low-dropout regulators manufactured by NXP Semiconductors. The series is characterized by ultra-high PSRR and miniaturized packaging options designed for portable electronics. The LD6805K/22H specifically denotes the 2.2 V fixed output version with a high-impedance disabled state.
Replacement Considerations
LD6805K/22P,115: Offers identical electrical specifications but includes an integrated pull-down switching transistor for auto discharge functionality in disabled mode instead of a high-ohmic state.
