Overview
The LD6805K/33H,115 is a linear voltage regulator IC manufactured by Nexperia USA Inc. It provides a fixed positive output voltage of 3.3 V with a maximum continuous output current of 150 mA. The device supports an input voltage range up to 5.5 V and features a maximum dropout voltage of 250 mV. It is housed in a DFN1010C-4 surface-mount package. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.
Feature Summary
- Provides a stable fixed 3.3 V output for low-power applications
- Capable of delivering up to 150 mA load current
- Operates with input voltages as high as 5.5 V
- Features a compact DFN1010C-4 surface-mount footprint
Applications
- Portable battery-powered devices requiring regulated 3.3 V logic levels
- Embedded systems utilizing CMOS technology
- Low-noise power supply stages for sensitive analog circuits
Procurement Notes
Verify the specific suffix H against the official Nexperia datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the DFN1010C-4 package. Confirm that the required output current does not exceed the 150 mA limit under expected thermal conditions. Check for any recent Product Change Notifications (PCN) regarding assembly sites or material changes.
Selection Notes
Select this component when a fixed 3.3 V rail is needed with minimal external components. The 150 mA rating suits moderate load requirements. Consider the 250 mV dropout voltage to ensure sufficient headroom between input and output voltages. The DFN1010C-4 package offers a small board area but requires adequate thermal management for sustained loads near the maximum rating.
Part Context
This part belongs to the LD6805K series of low-dropout regulators from Nexperia. These regulators are designed for efficiency and stability in space-constrained designs. The series typically includes various fixed output voltages to support different logic families. The K suffix often denotes specific thermal or electrical characteristics within the family lineup.
Replacement Considerations
Direct substitutes must match the 3.3 V output, 150 mA current capability, and DFN1010C-4 package. Verify pinout compatibility before substitution. Alternative LDOs from other manufacturers may require schematic adjustments if pin configurations differ.
