LD6836TD/13P,125

Product Overview

The LD6836TD/13P,125 from NXP USA Inc. is a fixed positive linear voltage regulator IC with one output. It provides a 1.3 V output at up to 300 mA and operates from an input voltage up to 5.5 V. The device uses a 5-TSOP surface-mount package, corresponding to an SC-74A, SOT-753 case, and includes an enable control feature.

Key Features

• Fixed positive output set to 1.3 V with a rated output current of 300 mA.
• Maximum input voltage of 5.5 V and 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 is included for output control.
• Protection features include over-current and over-temperature protection.
• Surface-mount 5-TSOP package in SC-74A, SOT-753 case.

Applications

• Regulated 1.3 V supply rail for low-power digital logic or sensor subsystems.
• Local post-regulation from a higher-voltage DC rail in compact board designs.
• Enable-controlled supply sequencing for portable electronic equipment.

Design & Procurement Notes

When using the LD6836TD/13P,125, verify that the available input voltage remains at or below 5.5 V while maintaining enough headroom above 1.3 V for the specified 0.2 V dropout at 300 mA. The fixed output voltage means no external adjustment is provided, so the 1.3 V rail must match the load requirement. The enable control feature can be used to manage the output, and over-current and over-temperature protection should be considered as part of the system design rather than as a substitute for proper input filtering, PCB layout, and thermal management. The 5-TSOP surface-mount package supports compact layouts within the specified -40°C to 85°C operating temperature range. Use the complete part number when documenting the design so the fixed 1.3 V output and 5-TSOP package are clearly identified.
