The 4 µA quiescent current makes it a candidate for battery-powered or always-on domains where the regulator's own draw must stay below the system sleep budget. Dropout voltage is 0.6 V maximum at the full 150 mA load — the input rail needs at least 3.6 V to hold regulation across the output current range. ## PSRR and noise rejection in the signal chain Power-supply rejection ratio is 60 dB at 1 kHz — this attenuates switching ripple from a preceding DC-DC converter by a factor of 1000 at that frequency. Above 1 kHz the PSRR rolls off — the typical curve in the datasheet (page 7 of the BH30PB1WHFV series) shows rejection dropping to around 30 dB at 100 kHz. Upstream switching noise above 100 kHz passes through unless filtered ahead of the LDO input. ## Package, footprint, and board integration The BH30PB1WHFV-TR is supplied in a SOT-665 package, also designated 5-HVSOF. The enable pin (Control Features: Enable) allows the output to be gated by a logic-level signal, reducing the quiescent current to near zero when the rail is not needed. Protection features include over-current, over-temperature, and soft-start — the soft-start limits inrush current into the output capacitor during power-up.","metaTitle":"ROHM BH30PB1WHFV-TR LDO Regulator, 3V Fixed, 150mA, SOT-665","metaDescription":"ROHM BH30PB1WHFV-TR LDO: 3V fixed output, 150mA, 60dB PSRR at 1kHz, 4µA Iq, SOT-665 package.
