Datasheet for Mitsumi MM3042~MM3045N low‑current CMOS regulator with ON/OFF control, covering specifications, pinout and typical applications.
The MM3042~MM3045N series is a low‑current (2.5 µA typ.) CMOS regulator with an ON/OFF control pin. It offers output voltages from 2.0 V to 5.5 V in 0.1 V steps and a minimum output current of 100 mA.
Typical applications include portable equipment, cellular phones, cordless phones and other battery‑powered devices. The device is supplied in a SOT‑25 package and requires an external output capacitor for stability.
| I/O voltage difference | 0.3 V typ. |
|---|---|
| Current consumption (ON state) | 2.5 µA typ. |
| Output current (minimum) | 100 mA |
| Output voltage range | 2.0 V – 5.5 V (0.1 V step) |
| ON/OFF control logic | High = OFF, Low = ON |
| Supply voltage range | -0.3 V – 9 V |
| Storage temperature | -40 °C – +125 °C |
| Operating temperature | -30 °C – +85 °C |
It provides an output voltage from 2.0 V to 5.5 V in 0.1 V steps.
The ON/OFF function is controlled by the CE pin: a high level turns the regulator off, a low level turns it on.
The regulator is supplied in a SOT‑25 (Mini mold) package.
