LD6836TD/16H,125

Product Overview

The LD6836TD/16H,125 from NXP USA Inc. is a surface-mount linear voltage regulator for positive fixed-output regulation in compact power-management circuits. The device has a 1.6 V output at up to 300 mA from an input voltage up to 5.5 V, with a maximum dropout of 0.2 V at 300 mA. It is housed in a 5-TSOP package, also identified as SC-74A, SOT-753, and includes an enable control feature along with over-current and over-temperature protection.

Key Features

• Positive fixed 1.6 V output regulator with a single output and 300 mA output current.
• Input voltage up to 5.5 V and maximum dropout voltage of 0.2 V at 300 mA.
• Quiescent current of 100 µA and maximum supply current of 250 µA.
• Power-supply rejection ratio of 55 dB at 1 kHz.
• Enable control feature.
• Over-current and over-temperature protection features.
• Operating temperature range from -40°C to 85°C.
• Surface-mount 5-TSOP package, also identified as SC-74A, SOT-753.

Applications

• Regulating a low-voltage rail for logic or analog subsystems in compact assemblies.
• Providing fixed positive voltage regulation for portable electronic modules where a small surface-mount package and enable control are useful.
• Supplying a defined 1.6 V rail for downstream circuits powered from inputs up to 5.5 V.
• Powering compact sensor or interface boards that need a single fixed output and over-current protection.

Design & Procurement Notes

Design considerations should account for the 1.6 V fixed output, 300 mA current capability, and 0.2 V maximum dropout at 300 mA when selecting the input rail and estimating headroom. The enable control feature should be considered when designing startup, standby, or fault-management sequencing. The 100 µA quiescent current and 250 µA maximum supply current are relevant for low-power budgeting, while the 55 dB PSRR at 1 kHz supports attention to noise-sensitive loads. The -40°C to 85°C operating range and surface-mount 5-TSOP package should be considered when evaluating the thermal environment. Procurement should specify the exact part number LD6836TD/16H,125 and the 5-TSOP package designation, also identified as SC-74A, SOT-753, to ensure the intended package and function are matched.
