R1190H031B-T1-FE

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

The R1190H031B-T1-FE is a low supply current Low Dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a fixed positive output voltage of 3.3 V with a maximum output current capability of 1 A. The device operates within an input voltage range of 3.5 V to 16 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It is housed in a compact SOT-89-5 surface-mount package, suitable for space-constrained designs. The component supports operation across a temperature range from -40°C to +85°C.

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

Verify the specific suffix 'T1' corresponds to the SOT-89-5 package configuration and reel packaging details. Confirm that the 'FE' designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's latest datasheet to ensure the pinout matches your PCB footprint design before finalizing procurement orders.

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

Select this component when a 1 A load current is required alongside minimal standby power drain. Ensure the input voltage remains above 3.5 V and below 16 V during all operating conditions. Consider the thermal dissipation limits inherent to the SOT-89-5 package if the voltage differential between input and output results in significant power loss under full load.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the R1190H series of LDO regulators, which are characterized by their ultra-low supply current and robust protection features. The series is designed for applications where energy efficiency is critical. The R1190H variant specifically integrates reverse current protection, distinguishing it from standard LDOs that may allow current to flow backward from the output to the input when the input voltage drops.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct replacements include other Nisshinbo R1190H series parts with compatible output voltages and packages, such as the R1190H033B-T1-FE for 3.3V or R1190H055B-T1-FE for 5V outputs, provided the pinout and thermal characteristics remain identical.
