General Electrical Characteristics for all voltage versions (Continued).
Unless otherwise specified all limits are at VIN = 2.4V, VLBI = 1.5V, Fosc = 300kHz, IOUT = 0mA and TA = 25°C. Test cir-
cuits of figure 1 and figure 2 for ILC6382-XX and ILC6382-ADJ respectively. BOLDFACE type indicates limits that apply
over the full operating temperature range. Note 2

Note 1. Absolute maximum ratings indicate limits which, when exceeded, may result in damage to the component. Electrical specifi-
cations do not apply when operating the device outside its rated operating conditions.
Note 2. Specified min/max limits are production tested or guaranteed through correlation based on statistical control methods.
Measurements are taken at constant junction temperature as close to ambient as possible using low duty pulse testing.
Note 3. VOUT (NOM) is the nominal output voltage at IOUT = 0mA.
Note 4. Guaranteed by design.
Note 5. In order to get a valid low-battery-output (LBO) signal, the input voltage must be lower than the low-battery-input (LBI) thresh-
old for a duration greater than the low battery hold time (thold(LBI)). This feature eliminates false triggering due to voltage transients at
the battery terminal.
