Technical data sheet for Seiko S-87x series high‑voltage, reset‑function voltage regulators.
The S-87x series from Seiko are low‑current, high‑precision voltage regulators with built‑in reset, delay or power‑off circuits. They are offered in a compact SOT‑89‑5 package and are suitable for lithium‑ion battery packs, video recorders, cameras and communication equipment.
The document provides detailed electrical characteristics, pin configurations for several variants (A‑G types), absolute maximum ratings, and a full product‑naming guide to select the appropriate part based on output voltage and detection voltage requirements. This manual is written in Chinese.
| Output voltage range | 2.6 V ~ 5.8 V (±2.4 %) |
|---|---|
| Dropout voltage (typical, 30 mA load) | 0.15 V at 5 V output |
| Quiescent current (operating) | 8 µA max |
| Quiescent current (sleep) | 3.5 µA max |
| Input voltage range | –0.3 V ~ +26 V |
| Operating temperature range | −40 °C ~ +85 °C |
| Package | SOT‑89‑5 |
The regulator draws up to 8 µA in normal operation.
The typical dropout voltage is 0.15 V under those conditions.
It operates from –40 °C to +85 °C.
They are supplied in a compact SOT‑89‑5 surface‑mount package.
