BD15HC0WEFJ-E2

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

The BD15HC0WEFJ-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable positive output voltage of 1.5 V with a maximum continuous output current of 1.0 A. The device operates within an input voltage range up to 10 V and features a typical dropout voltage of 600 mV at full load. It is housed in an HTSOP-J8 surface-mount package, suitable for space-constrained designs. The regulator supports an operating temperature range from -25°C to +85°C and includes built-in protection circuits for thermal shutdown and overcurrent conditions.
