S7133 is a bipolar linear integrated circuit produced by Panasonic. It can be used as a control circuit for battery-backed memory, undervoltage detection circuit for switch power supply, system reset circuit, with low current consumption, low reset output minimum guarantee voltage, and provided hysteresis voltage.
The S7133 is a bipolar linear integrated circuit designed for control of battery‑backed memory, preventing erroneous operations on power‑on/off and providing a resetting output for CPU‑mounted equipment such as PCs, printers and VTRs. It features low current consumption (300 pA typical low‑current, 30 µA typical high‑current) and a built‑in hysteresis voltage of about 50 mV.
The device is supplied in a TO‑92 package and its electrical specifications include a supply voltage range of –0.3 V to +15 V, power dissipation up to 400 mW, operating temperature from –30 °C to +75 °C, and storage temperature from –55 °C to +150 °C. Detailed pin connections, absolute maximum ratings, and characteristic curves are provided for design reference.
