R1154L120B-TR

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

The R1154L120B-TR is a fixed-output CMOS LDO voltage regulator manufactured by Nisshinbo Micro Devices. It provides a stable 12 V output with a maximum load current of 150 mA. The device operates within an input voltage range up to 24 V and maintains a typical dropout voltage of 300 mV at full load, with a maximum of 500 mV. Quiescent current is limited to 5 uA. Line regulation is specified at 0.05 %/V, and load regulation is 40 mV. Voltage accuracy is maintained within 2 %. Power dissipation is rated at 640 mW. It functions reliably across an operating temperature range from -40 °C to +105 °C.
