R1190H050B-T1-FE

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

The R1190H050B-T1-FE is a fixed-output low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 5 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 3.5 V to 16 V and features a typical dropout voltage of 1.1 V at full load. It includes built-in protection mechanisms such as overcurrent, thermal shutdown, and reverse current protection. The component is housed in a compact SOT-89-5 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated reverse current protection prevents backflow from the output to the input when the input voltage drops below the output level.
• Built-in thermal shutdown circuitry automatically limits power dissipation to protect the device during overheating conditions.
• Overcurrent protection limits the output current to safe levels, safeguarding both the regulator and the connected load.

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

• Battery-powered portable electronic devices requiring efficient linear regulation
• Industrial control systems needing stable 5 V logic supply rails
• Automotive electronics compatible with 12 V nominal battery architectures

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

Verify the specific suffix codes against official datasheets to confirm pinout compatibility and electrical tolerances. Ensure the ordering code matches the required package type and temperature rating. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Confirm RoHS compliance status for environmental regulations.

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

Select this component when a high-current 5 V LDO with reverse current protection is required. Compare dropout voltage specifications against available headroom in the power supply design. Evaluate thermal performance based on expected load currents and ambient operating temperatures. Consider package size constraints relative to PCB layout requirements.
