This document introduces ROHM's CMOS LDO regulator series for portable equipment. The products feature high accuracy output voltage, high ripple rejection ratio, and low dropout voltage.
The document describes the BH33MA3WHFV series of CMOS low‑dropout (LDO) regulators, covering their electrical specifications, typical performance curves, and recommended application circuits. It includes detailed tables of voltage ranges, current limits, dropout voltage, ripple rejection, and thermal protection features.
Block diagrams, package information (HVSOF5, HVSOF6), and design recommendations such as input/output capacitor selection, noise mitigation, and protection circuitry are also provided to aid designers in integrating these regulators into portable equipment.
| Maximum output current | 300 mA |
|---|---|
| Dropout voltage (100 mA load) | 60 mV |
