LD6806TD/23P,125

Product Overview

The LD6806TD/23P,125 from NXP USA Inc. is a linear voltage regulator IC with a positive fixed output, one regulator channel, and a 200 mA output current rating. It is packaged in a 5-TSOP surface-mount package, also identified as SC-74A or SOT-753. The device operates from an input voltage up to 5.5 V and provides a fixed 2.3 V output, with a maximum dropout voltage of 0.13 V at 200 mA. A quiescent current of 100 µA and a maximum supply current of 250 µA support low-power operation, while an enable control feature allows the output to be turned on or off under system control. Over-current and over-temperature protection are included, and the operating temperature range is -40°C to 85°C.

Key Features

• Positive fixed-output linear regulator with one regulator channel and a 2.3 V nominal output voltage.
• Rated for 200 mA output current with a maximum dropout voltage of 0.13 V at 200 mA.
• Supports input voltages up to 5.5 V and includes an enable control feature.
• Low quiescent current of 100 µA and maximum supply current of 250 µA.
• Includes over-current and over-temperature protection for regulated output operation.
• Surface-mount 5-TSOP package, also described as SC-74A or SOT-753.
• Operating temperature range from -40°C to 85°C.
• Power supply rejection ratio of 55 dB at 1 kHz.

Applications

• Regulating a 2.3 V rail for low-power digital or analog subsystems where a fixed linear supply is required.
• Providing a locally regulated voltage for portable electronics that need a 2.3 V supply and current limiting.
• Enabling or disabling a 2.3 V output under system control in power-managed circuits.
• Protecting downstream circuitry from overload or thermal stress in linear regulated supplies.
• Maintaining a fixed 2.3 V output from an input up to 5.5 V in compact surface-mount designs.

Design & Procurement Notes

When selecting this regulator, confirm that the available input voltage remains above 2.3 V plus the 0.13 V dropout margin, especially near the 200 mA output current limit. The enable control can gate the output in power-managed designs. The fixed output and 200 mA rating suit low-current rails rather than adjustable or higher-current architectures. The 5-TSOP surface-mount package, also identified as SC-74A or SOT-753, should be considered during PCB layout. Over-current and over-temperature protection reduce fault risk, but board-level thermal management and load limits still require verification. A PSRR of 55 dB at 1 kHz can be considered for noisy input rails.
