LD6836TD/23P,125

Product Overview

The LD6836TD/23P,125 from NXP USA Inc. is a linear voltage regulator IC that provides a fixed positive 2.3 V output from an input up to 5.5 V. The device is a single-output regulator rated for 300 mA, with a maximum dropout of 0.2 V at 300 mA. It is housed in a 5-TSOP surface-mount package, also identified as SC-74A/SOT-753, and operates over a temperature range of -40°C to 85°C.

Key Features

• Fixed positive 2.3 V output from a single regulator.
• 300 mA output current capability with 0.2 V maximum dropout at 300 mA.
• Maximum input voltage of 5.5 V.
• Quiescent current of 100 µA and maximum supply current of 250 µA.
• PSRR of 55 dB at 1 kHz.
• Enable control feature.
• Over-current and over-temperature protection.
• Surface-mount 5-TSOP package, SC-74A/SOT-753, with operating temperature -40°C to 85°C.

Applications

• Battery-powered portable electronics requiring a fixed 2.3 V rail.
• Low-current subsystems such as sensors, memory devices, or microcontroller peripherals.
• Compact surface-mount power management boards with a single regulated output.
• Enable-controlled output operation in low-power electronic assemblies.

Design & Procurement Notes

Designers should verify that the input voltage does not exceed 5.5 V and that sufficient headroom remains above 2.3 V to meet the 0.2 V dropout at the required load current. The 100 µA quiescent current and 250 µA maximum supply current support low-power design considerations, while the 300 mA output limit should be checked against peak load requirements. The enable control feature permits external control of the regulator, and the device includes over-current and over-temperature protection. Layout should account for the 5-TSOP surface-mount package and the -40°C to 85°C operating temperature range. Procurement reviews should confirm that the SC-74A/SOT-753 footprint matches the intended board design.
