LD6836TD/13H,125

Product Overview

The NXP USA Inc. LD6836TD/13H,125 is a fixed-output linear voltage regulator for single-output positive rail regulation. It provides a 1.3V output at up to 300mA and operates from an input voltage up to 5.5V, with a maximum dropout of 0.2V at 300mA. The device is housed in a 5-TSOP surface-mount package, corresponding to SC-74A/SOT-753, and includes an enable control feature. It provides over-current and over-temperature protection and operates from -40°C to 85°C. The quiescent current is 100 µA, the maximum supply current is 250 µA, and the PSRR is 55dB at 1kHz.

Key Features

• Fixed 1.3V positive output from a single regulator, delivering up to 300mA.
• Input voltage up to 5.5V with maximum dropout of 0.2V at 300mA.
• Enable control feature for regulator output control.
• Over-current and over-temperature protection.
• 100 µA quiescent current, 250 µA maximum supply current, and 55dB PSRR at 1kHz.
• Surface-mount 5-TSOP package, SC-74A/SOT-753, with -40°C to 85°C operating temperature.

Applications

• Low-voltage digital or logic subsystems requiring a fixed 1.3V positive rail.
• Enable-controlled power rails in compact surface-mount boards.
• Noise-sensitive single-output rails where PSRR and protection features are relevant.

Design & Procurement Notes

Design considerations include selecting an input voltage no higher than 5.5V and allowing dropout margin of at least 0.2V at 300mA to maintain the fixed 1.3V output. The enable control feature should be connected according to the desired output-on condition, and the over-current and over-temperature protections should be considered during load fault planning. Thermal design should account for the operating temperature range of -40°C to 85°C. Board layout should confirm footprint compatibility for the 5-TSOP, SC-74A/SOT-753 surface-mount package. The 100 µA quiescent current, 250 µA maximum supply current, and 55dB PSRR at 1kHz may guide low-power and noise-sensitive rail selection.
