Electrical Specifications Unless otherwise noted, V_IN = V_OUT + 0.4V, V_OUT = 1.8V, C_IN = C_OUT = 2.2µF, T_J = +25°C. Applications must follow thermal
guidelines of the package to determine worst case junction temperature. Please refer to “Applications Information” on page 8. Boldface limits apply over the
operating temperature range, -40°C to +125°C. (Continued)

NOTES:
9. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
10. Dropout is defined as the difference in supply V_IN and V_OUT when the supply produces a 2% drop in V_OUT from its nominal voltage.
11. I_PD is the internal pull down current that discharges the external SS capacitor on disable. I_CHG is the current from the SS pin that charges the
external SS capacitor during start-up.
