LD6806TD/25H,125

Overview

The LD6806TD/25H,125 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 2.5 V with a maximum continuous 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 (TSOP5) surface-mounted package. Key electrical characteristics include a low quiescent current of 1.0 µA in shutdown mode, 30 µV RMS output noise, and 55 dB power supply rejection ratio at 1 kHz.

Feature Summary

• Ultra-low dropout performance for high efficiency
• Low noise operation suitable for sensitive analog circuits
• High-ohmic output state when disabled
• Integrated thermal protection and current limiting

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices
• Analog and digital interfaces requiring lower than standard supply voltage

Procurement Notes

Verify that the suffix 'H' confirms the high-ohmic output state requirement for your specific circuit design. Ensure the ordering code matches the required SOT753 package variant. Confirm RoHS compliance status if restricted materials are a constraint for your manufacturing process.

Selection Notes

Select this component when a compact LDO with a fixed 2.5 V output is needed. The high-ohmic output feature distinguishes it from the 'P' variant, which offers a low-ohmic pull-down. Consider the 200 mA current limit and 5.5 V maximum input voltage when designing the power rail.

Part Context

This part belongs to the LD6806 series of ultra-low-dropout regulators designed for miniaturization. The series includes variants with different packages such as WLCSP4 and SOT886, and output states including both high-ohmic ('H') and low-ohmic ('P') configurations. All devices share the same monolithic silicon regulator design.

Replacement Considerations

LD6806TD/25P,125: Identical specifications except for the low-ohmic output state when disabled.
