Thermal Resistance Junction to Ambient
Battery low voltage detector input. The internal threshold is set to 0.6V. The external threshold
can be adjusted by using an external resistor divider.
Error amplifier output. Compensate it with a 220pF capacitor
Error amplifier input. The output voltage can be adjusted by using an external resistor divider

Input voltage.
This pin allows to select Low Noise/ Low Consumption Mode or to sychronize the device.
Battery low voltage detector output. If the voltage at the LBI pin drops below the internal
thrshold, LBO goes low. The LBO is an open drain output. A pull_up resistor should be
connected between the pin and the output voltage
