R1190S025B-E2-FE

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

The R1190S025B-E2-FE is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 2.5 V output with a maximum continuous current of 700 mA to 1 A, depending on thermal conditions and specific datasheet revisions. The device operates within an input voltage range up to 16 V and features a typical power supply rejection ratio (PSRR) of 60 dB. It is housed in a compact HSOP-6J-6 surface-mount package and supports operation across a temperature range from -40°C to +85°C.

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

Verify the exact output current rating (700 mA vs 1 A) against the specific datasheet revision, as sources vary. Confirm the HSOP-6J-6 package marking matches the E2 suffix requirements. Ensure the application circuit accounts for the specified dropout voltage and thermal dissipation limits within the operating temperature range.

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

Select this component when a fixed 2.5 V rail is required with moderate current demands. It is suitable for applications prioritizing low noise and simple implementation over high efficiency. Consider thermal management if the input-to-output differential voltage results in significant power dissipation within the small HSOP-6J-6 package.

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

This part belongs to the R1190S series of LDO regulators from Nisshinbo Micro Devices. The series offers various fixed output voltages and shares common characteristics such as low quiescent current and high PSRR. The R1190S025B variant specifically targets the 2.5 V output segment, differing from other series members primarily by its fixed voltage setting and associated thermal performance curves.

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

Direct pin-compatible substitutes within the same series include R1190S033B-E2-FE (3.3V) or R1190S050D-E2-FE (5V), provided the system voltage requirement changes. Cross-brand replacements require verification of pinout compatibility, current capacity, and dropout voltage specifications.
