LD6806F/30H,115

Overview

The LD6806F/30H,115 is a low-dropout regulator (LDO) from the NXP LD6806 series. It provides a fixed nominal output voltage of 3.0 V with a maximum continuous output current 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 an SOT886 surface-mounted package. Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 1.0 µA in shutdown mode. The regulator offers a typical power supply rejection ratio (PSRR) of 55 dB at 1 kHz and an RMS output noise voltage of 30 µV over a 10 Hz to 100 kHz bandwidth.

Procurement Notes

Verify that the specific part number corresponds to the high-ohmic (3-state) variant, as indicated by the 'H' suffix. Confirm the package type matches the required PCB footprint, specifically the SOT886 configuration. Ensure the ordering suffix aligns with the intended reel or tape specifications if applicable. Cross-reference the datasheet revision date to confirm the accuracy of the provided electrical parameters before finalizing procurement.

Selection Notes

Select this component for applications requiring precise 3.0 V regulation from varying input sources between 2.3 V and 5.5 V. The low quiescent current makes it suitable for battery-powered portable electronics where energy efficiency is critical. The integrated thermal and current protection simplifies system design by reducing the need for external monitoring components. Ensure the application environment stays within the specified ambient temperature range of -40 °C to +85 °C.

Part Context

This device belongs to the LD6806 series of ultra-low-dropout regulators designed for miniaturization. The series includes variants with different output voltages and package options, such as WLCSP4 and SOT753. The 'F' designation identifies the SOT886 plastic extremely thin small outline package. The 'H' suffix distinguishes the high-ohmic output behavior from the low-ohmic 'P' variants, which feature a pull-down switching transistor when disabled.
