LD6806TD/36P,125

Product Overview

The NXP USA Inc. LD6806TD/36P,125 is a single-output linear voltage regulator intended to provide a fixed positive 3.6 V rail from an input voltage up to 5.5 V. It is supplied in a surface-mount 5-TSOP package, corresponding to the SC-74A/SOT-753 outline, and can deliver 200 mA to a downstream load. The device includes an enable control feature and protection against over-current and over-temperature conditions. Its specified dropout is 0.13 V at 200 mA, and it is rated for operation from -40°C to 85°C.

Key Features

• Fixed positive 3.6 V output with 200 mA output current capability
• Input voltage maximum of 5.5 V
• Voltage dropout specified as 0.13 V at 200 mA
• Quiescent current of 100 µA and maximum supply current of 250 µA
• Power supply rejection ratio of 55 dB at 1 kHz
• Enable control feature for output regulation management
• Over-current and over-temperature protection features
• Surface-mount 5-TSOP package in SC-74A/SOT-753 outline
• Operating temperature range of -40°C to 85°C

Applications

• Low-current 3.6 V rail generation from 5 V logic supplies
• Enable-controlled power sequencing for single-output sensor or communication modules
• Battery-powered devices requiring a 200 mA fixed voltage with low quiescent current
• Surface-mount boards with limited space for an SOT-753/5-TSOP linear regulator

Design & Procurement Notes

When selecting this regulator, verify that the available input voltage remains at or below 5.5 V and that the load current does not exceed 200 mA. The 0.13 V dropout specification at 200 mA indicates the minimum headroom needed for regulation under that load condition, while the 100 µA quiescent current and 250 µA maximum supply current should be included in total power-budget calculations. The enable control can be used to manage the output state, and over-current and over-temperature protection should be considered together with the -40°C to 85°C operating range for thermal and environmental margin.
