FIELD: radio electronics. ^ SUBSTANCE: device includes a low-current transistor with two control resistors connected to a control resistor, a capacitor, and a power MIS transistor, which is connected to a startup resistor via a diode with a stratup capacitor. Also added are an additional transistor with two control resistors connected with the low-current transistor to form an asymmetric Schmitt trigger, a voltage holding circuit including a diode, a resistor, and a capacitor, which is connected in parallel with the startup capacitor and linked with the low-current transistor, an output voltage stabilising circuit including a transistor, a resistor, and a stabilitron, which is connected between the gate and the drain of the power MIS transistor. ^ EFFECT: lowering of power emitted from the startup resistor and the power transistor, and from the output voltage stabilising circuit. ^ 1 dwg |
