R1190S120D-E2-FE

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

The R1190S120D-E2-FE is a fixed-output low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 12 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 offers high power supply rejection ratio (PSRR) of 60 dB and maintains line regulation of 0.02 %/V. The unit consumes only 150 uA of quiescent current and ensures voltage accuracy within 1.5 %. It is housed in a compact HSOP-6J-6 surface-mount package and supports operation from -40 °C to +85 °C.

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

Verify the exact part number against official Nisshinbo documentation to ensure compatibility with your design requirements. Confirm that the HSOP-6J-6 package dimensions match your PCB footprint. Check for RoHS compliance status if required by your manufacturing standards. Ensure input voltage does not exceed the 16 V maximum rating during operation.

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

Select this component when a fixed 12 V output is required with minimal ground current draw. It is suitable for applications where space is limited due to its small HSOP-6J-6 package. Consider thermal dissipation capabilities, as power loss depends on the input-output voltage differential and load current. Verify that the 1 A current rating meets the peak demands of the target circuit.

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

This device belongs to the R1190S series of LDO regulators from Nisshinbo Micro Devices. The series is characterized by low standby current and high reliability. Other variants in the family offer different fixed output voltages while sharing similar electrical characteristics and packaging options. This specific model targets applications requiring a higher fixed output voltage compared to standard 3.3 V or 5 V regulators.

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

Direct substitutes may include other R1190S series parts with different output voltages if system architecture allows. Cross-reference with other manufacturers' 12 V, 1 A LDOs in HSOP-6J-6 packages, ensuring pinout and electrical specifications match. Verify thermal performance and PSRR requirements before substituting.
