(1) All voltages are with respect to the device GND terminal, unless otherwise stated.

(2) Minimum and maximum limits are ensured through test, design, or statistical correlation over the junction temperature (T_J) range of –40°C to 125°C, unless otherwise stated. Typical values represent the most likely parametric norm at T_A = 25°C, and are provided for reference purposes only.

(3) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (T_A-MAX) is dependent on the maximum operating junction temperature (T_J-MAX-OP = 125°C), the maximum power dissipation of the device in the application (P_D-MAX), and the junction-to ambient thermal resistance of the part/package in the application R_θJA), as given by the following equation: T_A-MAX = T_J-MAX-OP – (R_θJA × P_D-MAX). See Application and Implementation.

(4) Quiescent current is defined here as the difference in current between the input voltage source and the load at V_OUT.

(5) Ground current is defined here as the total current flowing to ground as a result of all input voltages applied to the device.

(6) Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100 mV below its nominal value.

(7) Short-circuit current (I_SC) for the LP5907-Q1 is equivalent to current limit. To minimize thermal effects during testing, I_SC is measured with V_OUT pulled to 100 mV below its nominal voltage.

(8) This specification is verified by design.

(9) There is a 1-MΩ resistor between EN and ground on the device.
