Step_down_regulator_with_short_circuit_protection

With this circuit, the low-battery detector (LBD) is connected to sense the output voltage, and shuts off the oscillator by forcing pin 2 low if the output voltage drops. Component values are tailored to circuit requirements, as described in Fig. 4-2, except: choose resistor values so that R5= R3 and R4= R2, and make R8 25 to 35 times higher than R3.
