Overview
The LD6805K/29P,115 is a fixed-output Low Dropout Regulator (LDO) from the NXP LD6805 series. It provides a nominal output voltage of 2.9 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 an auto discharge function via a pull-down switching transistor in disabled mode. Key electrical characteristics include a Power Supply Rejection Ratio (PSRR) of 75 dB at 1 kHz and a typical quiescent current of 35 µA.
Feature Summary
- Features an integrated pull-down switching transistor that ensures a low-ohmic output state when the device is disabled, facilitating rapid output voltage discharge.
- Delivers high power supply rejection ratio performance to suppress input noise and ripple signals effectively.
- Manufactured using monolithic silicon technology within a compact plastic package designed for space-constrained portable applications.
Applications
- Powering analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Supplying power to smart phones, mobile phone handsets, and cordless telephones
- Providing regulated voltage for digital still cameras, mobile internet devices, and personal navigation devices

Selection Notes
Select this component when a stable 2.9 V rail is required with minimal board space. The LD6805K/29P,115 is suitable for designs needing fast output discharge upon shutdown. Ensure the application input voltage remains between 2.3 V and 5.5 V. Confirm that the external load capacitance meets the minimum stability requirements specified in the datasheet.
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 small form factor packages. The 'K' designation indicates a specific version within the family, while the '/29' specifies the fixed output voltage. The 'P' suffix denotes the variant equipped with the auto-discharge pull-down feature.
Replacement Considerations
Compatible substitutes within the same family include other LD6805K variants with different output voltages or the high-ohmic 'H' suffix versions if auto-discharge is not required. Cross-family replacements require matching input/output voltage ranges, current ratings, and package dimensions.
FAQ
What is the behavior of the output pin when the enable signal is low?
The LD6805K/29P contains a pull-down switching transistor that activates in disabled mode, providing a low-ohmic output state to automatically discharge the output capacitor.
Does this regulator support automotive applications?
No. Unless explicitly stated otherwise in the data sheet, this product is not automotive qualified and is not tested according to automotive standards.
