PSRR is 60dB at 1kHz, a useful figure for cleaning up ripple from a preceding buck converter before it reaches a sensitive analog or RF load. ## Protection and control for sequenced power-up An Enable pin lets the system power this rail on command, while integrated over-current, over-temperature, and soft-start protect the load and the regulator itself during startup or fault conditions. ## Package and sourcing reality Housed in a SOT-665 (also called 5-HVSOF), this is a surface-mount package suited for compact PCB layouts in handheld or space-constrained designs. Supplied in tape and reel or cut tape options. Sourced to order against the BOM; availability and current pricing confirmed at RFQ time.","metaTitle":"ROHM BH18PB1WHFV-TR LDO 1.8V 150mA, SOT-665","metaDescription":"ROHM BH18PB1WHFV-TR active LDO, 1.8V fixed output, 150mA, 60dB PSRR at 1kHz, 4µA Iq, SOT-665.
