BD3574YHFP-MTR

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

The BD3574YHFP-MTR is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5 V output with a maximum continuous current of 500 mA. The device supports an input voltage range from 5.5 V to 36 V and operates within an ambient temperature range of -40°C to +125°C. Key electrical specifications include a typical ripple rejection ratio of 55 dB at 120 Hz, a quiescent current of 30 µA, and a maximum dropout voltage of 480 mV at full load. The unit is housed in an HRP-5 surface-mount package.
