General Electrical Characteristics for all voltage versions.

Unless otherwise specified all limits are at VIN = 2.4V, VIRI = 1.5V, Fosc = 300kHz, IOUT = 0mA and TA = 25°C. Test cir-

cuits of figure 1 and figure 2 for ILC6382CIR-XX and ILC6382CIR-ADJ respectively. BOLDFACE type indicates limits

that apply over the full operating temperature range. Note 2.
