LD6836TD/27H,125

Product Overview

LD6836TD/27H,125 from NXP USA Inc. is a single-output linear voltage regulator that provides a fixed positive 2.7V rail at up to 300mA. The device accepts input voltages up to 5.5V, and the maximum dropout is 0.2V at 300mA. It includes an enable control feature and protection against overcurrent and overtemperature. The 5-TSOP package corresponds to SC-74A or SOT-753, supports surface-mount assembly, and the operating temperature range is -40°C to 85°C.

Key Features

• Fixed 2.7V positive output for single-rail power delivery
• 300mA output current with 0.2V maximum dropout at full load
• Maximum input voltage of 5.5V
• Low quiescent current of 100 µA and maximum supply current of 250 µA
• 55dB PSRR at 1kHz supports input ripple rejection
• Enable control feature for output control
• Overcurrent and overtemperature protection features
• Surface-mount 5-TSOP package, SC-74A or SOT-753
• Operating temperature range of -40°C to 85°C

Applications

• Regulated 2.7V supply for low-power digital logic and microcontroller peripheral rails
• Power rail for sensor modules, communication peripherals, or interface devices within the 5.5V input limit
• Compact surface-mount regulator in battery-operated portable electronics where enable control and low quiescent current are useful

Design & Procurement Notes

Designers should confirm that the input supply remains within the maximum 5.5V and provides sufficient headroom above the fixed 2.7V output, particularly at the 300mA load point where the maximum dropout is 0.2V. The enable feature can be incorporated into system power sequencing or standby control, while the overcurrent and overtemperature protections should be considered alongside board-level thermal design. The fixed output provides a single 2.7V rail, and the surface-mount 5-TSOP package should be matched to the PCB footprint and assembly process. The -40°C to 85°C operating temperature range should be checked against the intended environmental conditions.
