SI-3010KD

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The SI-3010KD is a linear regulator IC from the SI-3000KD series with a maximum output current of 1 A. Its output voltage is adjustable via external resistors connected to the ADJ pin. The device incorporates a built-in low saturation PNP bipolar transistor, enabling operation with a low input/output voltage difference (dropout voltage ≤ 0.6 V at 1 A). It features an Output On/Off function controlled by the VC pin, fold-back Overcurrent Protection (OCP), and auto-restart Thermal Shutdown (TSD).

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What type of overcurrent protection does the SI-3010KD feature?

It features fold-back overcurrent protection, where the output current during a short circuit is smaller than the activation current, reducing power loss.

Can ceramic capacitors be used as the output capacitor for the SI-3010KD?

No, the datasheet specifies that electrolytic capacitors must be used for the output capacitor to ensure stability; ceramic capacitors may cause oscillation.
