(1) All voltages are with respect to the device GND pin.
(2) Minimum and maximum limits are ensured through test, design, or statistical correlation over the 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) C_IN, C_OUT: Low-ESR Surface-Mount-Ceramic Capacitors (MLCCs) used in setting electrical characteristics.
(4) The device maintains a stable, regulated output voltage without a load current.
(5) Quiescent current is defined here as the difference in current between the input voltage source and the load at V_OUT. I_Q = (I_IN – I_OUT)
(6) Output reverse current (I_RO) is measured at the IN pin.
(7) Ground current is defined here as the total current flowing to ground as a result of all input voltages applied to the device.
(8) 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. Dropout voltage is not a valid condition for output voltages less than 1.3 V as compliance with the minimum operating
input voltage can not be ensured.
(9) This specification is verified by design.
(10) There is a 1-MΩ resistor between EN and ground on the device.
