Note 1: The Minimum V_INhas to meet two conditions: V_IN≥ 2.7V and V_IN≥ V_RX+ V_DROPOUT,V_RX= V_R1or V_R2

2: _RXis the regulator output voltage setting.

3: TCV_OUT2= ((V_OUT2max– V_OUT2min) * 10⁶)/(V_OUT2* D_T).

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. T_A, T_J, θ_JA). Exceeding the maximum allowable power

dissipation causes the device to initiate thermal shutdown.

7: The integrated MOSFET switches have an integral diode from the L_Xpin to V_IN, and from L_Xto P_GND. 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.

V_IN1and V_IN2are supplied by the same input source.
