R1191L028D-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The R1191L028D-TR is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 2.8V output with a maximum current capacity of 300mA. The device supports an input voltage range up to 16V and features a typical power supply rejection ratio (PSRR) of 70dB at 1kHz. Key electrical characteristics include a quiescent current of 100µA, a line regulation of 0.02%/V, and a load regulation of 50mV. It operates within a temperature range of -40°C to +85°C and includes protection against over-temperature, reverse current, and short circuits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'D-TR' matches the required DFN1616-6 package and reel quantity. Confirm that the fixed 2.8V output aligns with system requirements. Ensure compatibility with the 16V maximum input limit. Check RoHS compliance status if restricted substances are a concern. Validate lead times as production schedules may vary.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a compact surface-mount LDO with reverse current protection is needed. The DFN1616-6 package suits space-constrained designs. Consider the 100µA quiescent current for battery life optimization. Verify that the 300mA output current meets peak load demands without exceeding thermal limits.
