R1180N251C-TR-YE

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

The R1180N251C-TR-YE is a high-reliability industrial LDO regulator from the R1180x-Y series, manufactured by Nisshinbo Micro Devices. It provides a fixed 2.5V output with ±2.0% accuracy and supports up to 150mA load current. The device operates within a wide input voltage range of 1.7V to 6.0V and features an extremely low supply current of typically 1.0µA. Designed for harsh environments, it withstands temperatures from -50°C to 105°C. Packaged in SOT-23-5, it includes built-in fold-back protection circuits and requires only a 0.1µF ceramic output capacitor for stable operation.

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

Verify that the specific part number suffix indicates the correct package type and pin configuration before integration. Confirm that the application environment stays within the specified -50°C to 105°C operating temperature range to ensure long-term reliability. Ensure that the input voltage does not exceed the maximum rating of 6.5V to prevent permanent damage to the device.

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

Select this component when a fixed 2.5V output is required for industrial-grade stability. The C suffix denotes the absence of a Chip Enable pin, which is suitable for always-on applications. Consider the SON1612-6 package option if higher power dissipation capabilities are needed compared to the SOT-23-5 variant. Verify compatibility with the required load current and input voltage range for the target system design.
