Overview
The LD6805K/36P,115 is a fixed-output Low Dropout Regulator (LDO) from the NXP LD6805 series. It provides a nominal output voltage of 3.6 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 an auto discharge function via a pull-down switching transistor in disabled mode. The regulator delivers high power supply rejection ratio (PSRR) performance and low quiescent current.
Feature Summary
- Integrated pull-down switching transistor providing a low-ohmic output state for rapid discharge when disabled
- High power supply rejection ratio (PSRR) capability to suppress input noise and ripples
- Low quiescent current consumption in shutdown mode to extend battery life
- Monolithic silicon technology construction with integrated over-current protection
Applications
- Powering analog and digital interfaces requiring lower than standard supply voltages
- Mobile appliances such as smart phones, mobile phone handsets, and cordless telephones
- Portable media players and personal navigation devices
- Digital still cameras and mobile internet devices
Procurement Notes
Verify that the specific suffix ',115' corresponds to the intended tape-and-reel packaging configuration as defined by NXP Semiconductors. Confirm the nominal output voltage matches the '36' designation for 3.6 V. Ensure the 'P' variant is selected if the auto-discharge feature is required for the application design.
Selection Notes
Select this component when a stable 3.6 V rail is needed from a variable input source between 2.3 V and 5.5 V. The P-suffix is mandatory if fast output discharge upon shutdown is necessary. Verify that the external load capacitance meets the minimum stability requirements specified in the datasheet.
Part Context
This part belongs to the LD6805 series of ultra-small LDO regulators designed for portable applications. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. The 'xxP' designation indicates the inclusion of an auto-discharge function, distinguishing it from the 'xxH' variants which maintain a high-impedance state when disabled.
Replacement Considerations
LD6805K/36H,115: Provides identical electrical specifications but lacks the auto-discharge pull-down transistor, maintaining a high-ohmic state when disabled.
