Description

The SI-3000KM series are series regulator ICs which use a hyposaturation-type PNP bipolar transistor in the power section, and are capable of operating with small difference between input-output voltages. Each of the products has an ON/OFF terminal which operates in Active High mode; and current consumption during OFF condition falls to nearly zero.
The SI-3000KM series offers two product groups: 17V-input products (SI-3012KM, SI-3025KM, and SI-3033KM) can use a ceramic capacitor as the output capacitor; and high-voltage products (35V-input: SI-3010KM, SI-3050KM, SI-3090KM, and SI-3120KM) can use an electrolytic capacitor as the output capacitor.
