LD6806F/14P,115

Product Overview

The LD6806F/14P,115 from NXP USA Inc. is a single-output, positive, fixed linear voltage regulator in a 6-XSON, SOT886 (1.45x1) surface-mount package. It provides a fixed 1.4V output at up to 200mA, with a maximum input voltage of 5.5V and a maximum dropout of 0.13V at 200mA. The device includes an enable control and overcurrent and overtemperature protection, and is specified for operation from -40°C to 85°C.

Key Features

• Fixed 1.4V positive output from a single regulator, suitable for low-voltage loads up to 200mA.
• Maximum input voltage of 5.5V and dropout voltage of 0.13V at 200mA.
• Enable control for output on/off management.
• Overcurrent and overtemperature protection features.
• Quiescent current of 100 µA and maximum supply current of 250 µA.
• PSRR of 55dB at 1kHz.
• Surface-mount 6-XSON, SOT886 (1.45x1) package.

Applications

• Fixed 1.4V rail for compact battery-powered electronics where a low-current regulated voltage is required.
• Enable-controlled power delivery in small embedded boards or sensor assemblies.
• Protected supply point for handheld or portable equipment operating within -40°C to 85°C.

Design & Procurement Notes

Design considerations should account for the 5.5V maximum input, the fixed 1.4V output, and the 200mA output limit when selecting the regulator for a load. The 0.13V dropout at 200mA helps maintain regulation when input headroom is limited, while the enable control can be used to control output state in system power sequencing. Overcurrent and overtemperature protection features support fault protection in simple single-rail designs, but thermal and layout margins should still be evaluated for the 6-XSON, SOT886 (1.45x1) surface-mount package. The specified operating temperature range from -40°C to 85°C should be checked against the final board environment.
