The minimum V IN has to meet two conditions: V IN ≥ 2.7V and V IN ≥ V OUT + 0.5V.
Reference Feedback Voltage Tolerance applies to adjustable output voltage setting.
V R is the output voltage setting.
Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load
regulation is tested over a load range of 0.1 mA to the maximum specified output current. Changes in
output voltage due to heating effects are covered by the thermal regulation specification.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
temperature and the thermal resistance from junction to air (i.e. T A , T J , θ JA ). Exceeding the maximum
allowable power dissipation causes the device to initiate thermal shutdown.
The internal MOSFET switches have an integral diode from the L X pin to the V IN pin, and from the L X pin
to the GND pin. In cases where these diodes are forward-biased, the package power dissipation limits
must be adhered too. Thermal protection is not able to limit the junction temperature for these cases.
The current limit threshold is a cycle-by-cycle current limit.
