LD6806TD/20P,125

Product Overview

The LD6806TD/20P,125 from NXP USA Inc. is a linear voltage regulator IC with a positive fixed output. It provides a single regulated output at 2V, with an output current of 200mA. The device has a maximum input voltage of 5.5V and specifies a maximum dropout voltage of 0.13V at 200mA. It is housed in a surface-mount 5-TSOP package, also identified as SC-74A or SOT-753, and operates over a temperature range from -40°C to 85°C.

Key Features

• Single positive fixed linear regulator output set at 2V
• 200mA output current with 0.13V maximum dropout at 200mA
• Maximum input voltage of 5.5V
• Quiescent current of 100 µA and maximum supply current of 250 µA
• PSRR of 55dB at 1kHz
• Enable control feature for regulator output control
• Over-current and over-temperature protection features
• Surface-mount 5-TSOP package, SC-74A/SOT-753

Applications

• Fixed 2V rail for low-current circuit blocks
• Battery-powered portable electronics needing linear regulation
• Microcontroller peripheral power domains using enable control
• Surface-mount embedded systems with input voltages up to 5.5V
• Compact power stages limited to 200mA output

Design & Procurement Notes

When selecting this regulator, verify that the input voltage remains within 5.5V and that the required load current does not exceed 200mA. The fixed 2V output means the supply must provide sufficient headroom, especially because the maximum dropout voltage is 0.13V at 200mA. The enable control can be used to manage output enablement during system sleep or sequencing, while over-current and over-temperature protection should be considered as part of the power-stage design. The 55dB PSRR at 1kHz can be evaluated against input supply noise, and board layout should account for the surface-mount 5-TSOP package and the -40°C to 85°C operating range.
