Conditions
Note 1:
The Minimum VIN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ VRX + VDROPOUT, VRX = VR1 or VR2.
2:
VRX is the regulator output voltage setting.
3:
TCVOUT2 = ((VOUT2max – VOUT2min) * 106)/(VOUT2 * DT).
4:
Regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is tested
over a load range from 0.1 mA to the maximum specified output current.
5:
Dropout voltage is defined as the input-to-output voltage differential at which the output voltage drops 2% below its
nominal value measured at a 1V differential.
6:
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction
temperature and the thermal resistance from junction to air. (i.e. TA, TJ, θJA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown.
7:
The integrated MOSFET switches have an integral diode from the LX pin to VIN, and from LX to PGND. In cases where
these diodes are forward-biased, the package power dissipation limits must be adhered to. Thermal protection is not
able to limit the junction temperature for these cases.
8:
VIN1 and VIN2 are supplied by the same input source.
