LD6836TD/16P,125

Product Overview

The LD6836TD/16P,125 from NXP USA Inc. is a fixed-output linear voltage regulator intended for compact surface-mount power management. It provides a single positive 1.6 V output at up to 300 mA from input supplies rated up to 5.5 V. The device includes an enable control and integrates over-current and over-temperature protection, supporting regulated low-voltage rails in space-constrained electronic assemblies.

Key Features

• Fixed positive 1.6 V output with a maximum output current of 300 mA
• Maximum input voltage of 5.5 V and dropout voltage of 0.2 V at 300 mA
• Enable control for managed output operation
• Over-current and over-temperature protection
• Quiescent current of 100 µA and supply current of 250 µA maximum
• Power-supply rejection ratio of 55 dB at 1 kHz
• Operating temperature range of -40°C to 85°C
• 5-TSOP surface-mount package, SC-74A / SOT-753

Applications

• Regulating a low-voltage 1.6 V rail for digital logic or mixed-signal circuitry
• Providing local linear regulation from supplies within the 5.5 V input limit
• Enabling controlled output sequencing in compact board-level power sections
• Supporting protected low-current sensor or interface circuits that require a fixed 1.6 V supply

Design & Procurement Notes

Designers should verify that the available input voltage remains above the 1.6 V output plus the 0.2 V dropout margin at the required load current. The fixed output voltage cannot be adjusted, so the system rail must match 1.6 V. The enable pin should be driven according to the intended power-up or shutdown behavior, and the regulator's over-current and over-temperature protections should be considered as safeguards rather than substitutes for proper input selection and thermal management. The 100 µA quiescent current and 5-TSOP package support compact layouts, while the -40°C to 85°C operating range defines the ambient temperature envelope for normal use.
