9e102 Datasheet Jun 2026

Many versions feature a ferrite core shielding to minimize Electromagnetic Interference (EMI) with neighboring components on a crowded PCB.

The IC comes in an 8-pin SOP-J8 package, providing a balance of compact size and easy routing. High-side MOSFET drive supply pin. VINcap V sub cap I cap N end-sub : Input power supply pin. EN: Enable pin (shutdown/startup). AGND: Analog ground. FB: Feedback input pin. COMP: Compensation pin. PGND: Power ground. SW: Switching output pin. 6. Layout Guidelines 9e102 datasheet

That recognition required a new kind of care. The module’s exchanges had moral gravity. Fixing one thing might mean capturing a joke someone had made in a hospital corridor; restoring a sensor’s signal might mean the module kept a lullaby someone had used to coax a child to sleep. Sometimes the memories it held were dangerous: a pattern of a lock, the cadence of a vault's release, a password hummed as a song. The object did not differentiate between warmth and weapon. Mara set rules. Many versions feature a ferrite core shielding to

Mara took 9e102, and Elias’s request was like tuning a radio between stations. She closed her eyes and listened. The module produced a filament of sound—a child’s laughter caught between languages, the slap of a boot on a stone stairs—and then it went dark. It did not offer the hour Elias asked for. It offered something else: a memory of a mapmaker standing at a cliff at high noon, staring at a spread of charted ocean. The mapmaker lowered his head and cut the map with a knife, folding the shoreline into a neat, unreadable packet. The mapmaker then walked inland and never spoke of why he had done it.

Outside her window, a courier’s drone had hovered and taken the crate that had been labeled 9e102. No one left a note. The crate's seal was unbroken but its contents were empty. On the table, the single folded datasheet lay open, the lines of its schematic smudged into new shapes, as if someone had drawn over the missing parts. The hand-etched code remained: 9e102. The amber pin’s light, in her palm, was only the memory of a light.

Enable input. Pull high to turn on the regulator, pull low for 0μA standby mode. Analog ground for sensitive internal reference circuitry. FB

A minority of component listings also show a device labeled simply “9E102” in an SOP-8 package, with specifications distinct from the BD9E102FJ. However, the overwhelming majority of references to “9e102 datasheet” lead directly to the ROHM BD9E102FJ.
