LD6806TD/25P,125

Product Overview

The LD6806TD/25P,125 from NXP USA Inc. is a positive, fixed-output linear voltage regulator that provides a single 2.5 V output from input voltages up to 5.5 V. It can deliver up to 200 mA and specifies a maximum dropout of 0.13 V at 200 mA. Quiescent current is 100 µA, with a maximum supply current of 250 µA. The device includes an enable control feature, over-current and over-temperature protection, and 55 dB PSRR at 1 kHz. It is a surface-mount part in a 5-TSOP package (SC-74A, SOT-753) with an operating temperature range of -40°C to 85°C.

Key Features

• Fixed positive 2.5 V output from a single regulator.
• 200 mA output current with 0.13 V maximum dropout at 200 mA.
• Input voltage rating up to 5.5 V.
• Enable control, over-current protection, and over-temperature protection.
• 100 µA quiescent current and 250 µA maximum supply current.
• 55 dB PSRR at 1 kHz.
• 5-TSOP surface-mount package (SC-74A, SOT-753).
• Operating temperature range of -40°C to 85°C.

Applications

• Generating a fixed 2.5 V rail for logic, sensor, or interface circuits.
• Providing local linear regulation in compact surface-mount assemblies where up to 200 mA is needed and dropout margin is limited.
• Using the enable control for power sequencing or standby management in a regulated subsystem.

Design & Procurement Notes

Verify that the input voltage does not exceed 5.5 V and remains high enough to maintain the 2.5 V output under load, using the 0.13 V dropout at 200 mA. The output is fixed, so confirm that 2.5 V matches the load requirement. The enable feature supports controlled operation, but the intended control behavior should be checked against the circuit requirements. Over-current and over-temperature protection are useful for fault management, while the 100 µA quiescent current and 250 µA maximum supply current affect low-power calculations. Consider the 5-TSOP surface-mount package and -40°C to 85°C operating range during layout and thermal planning.
