    Products Detail

    The PT6120 series is a low voltage input (typically 7V) integrated switching regulator family offering 1A output current. It features 89% typical efficiency, adjustable output voltage, internal short circuit protection, over-temperature protection, and on/off control (ground off). Designed with premium low threshold FETs, these regulators are ideal for applications requiring very low input/output voltage differentials such as battery-powered equipment. Quiescent current in shutdown mode is less than 100µA.

    Key Features

    • Adjustable Output Voltage, Internal Short Circuit Protection, Over-Temperature Protection, On/Off Control (Ground Off), High Efficiency (89% typical), Low Quiescent Current (<100µA shutdown), Low Voltage Input (7V typical)

    Application scenarios

    • Battery powered equipment
