Overview
The LD6806TD/14P,125 is a low-dropout regulator (LDO) from NXP Semiconductors. It provides a fixed 1.4 V output with a maximum current rating of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 60 mV at full load. It utilizes the SOT753 surface-mounted package. This variant includes a pull-down switching transistor that ensures a low-ohmic output state when disabled.
Feature Summary
- Ultra-low dropout voltage for high efficiency
- Low noise performance suitable for sensitive analog circuits
- Integrated thermal protection and current limiting
- Active HIGH enable pin with shutdown capability
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
- Media players
Procurement Notes
Verify the specific suffix '14P' confirms the 1.4 V nominal output voltage and the low-ohmic disabled state. Confirm the '125' suffix aligns with the required operating temperature range and reliability specifications. Ensure the SOT753 package type matches the PCB footprint design requirements.
Selection Notes
Select this component for applications requiring miniaturization and stable power delivery in mobile environments. Consider the low quiescent current in shutdown mode for battery-powered systems. Evaluate the need for the low-ohmic output state during disable periods compared to high-ohmic alternatives.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators designed for component miniaturization. The series offers various output voltages and packages, including WLCSP4, SOT886, and SOT753. The 'TD' designation specifically identifies the SOT753 plastic surface-mounted package variant.
