Overview
The LD6805K/16P,115 is a fixed-output Low DropOut regulator from the NXP LD6805 series. It provides a nominal output voltage of 1.6 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 dropout voltage of 250 mV at full load. It incorporates an integrated pull-down switching transistor that ensures a low-ohmic output state in disabled mode for auto discharge functionality. The component utilizes a DFN1010C-4 (SOT1194-1) plastic package measuring 1 x 1 mm.
Feature Summary
- Features high power supply rejection ratio for effective noise suppression
- Includes auto discharge function via pull-down transistor in disabled mode
- Operates with low quiescent current during shutdown
- Integrated electrostatic discharge protection
Applications
- Powering analog and digital interfaces requiring lower than standard supply voltages
- Mobile appliances such as smart phones and cordless telephones
- Portable media players and personal navigation devices
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm package type and marking codes. Confirm RoHS compliance status and environmental declarations prior to procurement. Ensure application requirements align with the specified operating temperature range and absolute maximum ratings defined in the datasheet.
Selection Notes
Select this variant when a fixed 1.6 V output is required alongside active discharge capabilities upon shutdown. Compare against the 'H' suffix variants if a high-impedance output state is preferred instead of auto discharge. Verify that the external load capacitance meets stability requirements for the intended operating conditions.
Part Context
This component belongs to the LD6805 series of low-dropout regulators manufactured by NXP Semiconductors. The series is designed for portable applications requiring miniaturization and superior operating stability. The 'P' designation indicates the inclusion of a pull-down switching transistor for output discharge, distinguishing it from the 'H' series which maintains a high-ohmic state.
