RN5RL51AA-TR-FE

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

The RN5RL51AA-TR-FE is a low-dropout (LDO) voltage regulator manufactured by Nisshinbo Micro Devices. It provides a fixed output voltage of 5.1 V with a maximum output current capability of 50 mA. The device operates within an input voltage range that supports regulation down to a dropout voltage of approximately 40 mV at rated load. It features a quiescent current of 1 uA, ensuring minimal power consumption in standby modes. The component is housed in a compact SOT-23-5 surface-mount package and is designed for operation across a temperature range from -40°C to +85°C.
