LD6806TD/14H,125

Product Overview

The LD6806TD/14H,125 from NXP USA Inc. is a single-output, positive, fixed linear voltage regulator intended for surface-mount power management. It provides a fixed 1.4 V output at up to 200 mA, accepts input voltages up to 5.5 V, and specifies a maximum dropout of 0.13 V at 200 mA. The device includes an enable control feature and overcurrent and overtemperature protection. It uses a 5-TSOP package, corresponding to SC-74A/SOT-753, and is rated for operation from -40°C to 85°C.

Key Features

• Fixed positive output of 1.4 V at up to 200 mA.
• Maximum input voltage of 5.5 V and dropout of 0.13 V at 200 mA.
• Enable control with overcurrent and overtemperature protection.
• 100 µA quiescent current, 250 µA maximum supply current, and 55 dB PSRR at 1 kHz.
• Surface-mount 5-TSOP package, SC-74A/SOT-753, operating temperature -40°C to 85°C.

Applications

• Generating a fixed 1.4 V rail for loads up to 200 mA in compact surface-mount boards.
• Enable-controlled power domains where the regulator output can be turned on or off.
• Protected linear regulation in designs that require overcurrent and overtemperature safeguards.
• Low-dropout regulation from input voltages up to 5.5 V.

Design & Procurement Notes

For design use, confirm that the system input voltage remains within the specified maximum of 5.5 V while still providing enough headroom for the 1.4 V fixed output and the 0.13 V dropout condition at the intended load current. The 200 mA output rating should be treated as the maximum current available from this single regulator. The enable control can be used to gate the output, while the overcurrent and overtemperature protection functions address fault conditions. The 100 µA quiescent current and 250 µA maximum supply current are relevant for power budgeting, and the 55 dB PSRR at 1 kHz should be considered when input noise is a concern. Layout should account for the 5-TSOP surface-mount package, SC-74A/SOT-753, and the rated operating range of -40°C to 85°C.
