Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.

Note 2: The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin. Test method is per JESD22-A114.

Note 3: Refer to JEDEC J-STD-020C for surface mount device (SMD) package reflow profiles and conditions. Unless otherwise stated, the temperatures and

times are for Sn-Pb (STD) only.

Note 4: Device operation must be evaluated, and derated as needed, based on ambient temperature (T

junction temperature (T

Note 5: Output voltage line regulation is defined as the change in output voltage from the nominal value (

ΔV

(

ΔV

Note 6: Output voltage load regulation is defined as the change in output voltage from the nominal value (

(

ΔI

Note 7: The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the output

voltage tolerance specification.

Note 8: Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. For the LP38511-1.8,

the minimum V

Note 9: The ERROR Flag thresholds are specified as percentage of the nominal regulated output voltage. See Application Information.
