LD6806F/28H,115

Overview

The LD6806F/28H,115 is a low-dropout regulator (LDO) from NXP with a fixed 2.8 V output and 200 mA current rating. It 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. The device provides ultra-low noise performance with a typical RMS output noise of 30 µV across the 10 Hz to 100 kHz bandwidth. It includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model. When disabled, the high-ohmic variant maintains a high-impedance state at the output pin.

Feature Summary

• Ultra-low dropout voltage for efficient power management
• Low quiescent current in shutdown mode
• Integrated thermal protection and current limiter
• High-ohmic output state when disabled

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices
• Media players

Procurement Notes

Verify the specific suffix 'H' confirms the high-ohmic output configuration required by your circuit design. Ensure the ordering code matches the SOT886 package type. Confirm RoHS compliance and dark green material status if halogen-free requirements are mandatory for your assembly process.

Selection Notes

Select this component for applications requiring precise 2.8 V regulation with minimal voltage drop. Consider the SOT886 package dimensions for space-constrained layouts. Verify that external capacitors meet the minimum capacitance and ESR specifications to ensure stability under all operating conditions.

Part Context

This part belongs to the LD6806 series of small-size LDO regulators designed for mobile appliances. The series offers various output voltages and packages, including WLCSP4, SOT886, and SOT753. The 'F' designation indicates the SOT886 leadless plastic package, while 'H' specifies the high-ohmic output behavior upon disablement.

Replacement Considerations

LD6806F/28P,115: Identical electrical characteristics but features a low-ohmic output state when disabled instead of high-ohmic.
