Electrical Specifications
VIN = 12V, SHDN# = EN3 = EN5 = VCC, SKIP# = FB3 = FB5 = 0V, I_LDO5 = 0mA, I_LDO3 = 0mA, C_REF = 0.22µF,
C_LDO3 = C_LDO5 = 4.7µF, T_A = -10°C to +100°C (Note 2). Parameters with MIN and/or MAX limits are 100%
tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not
production tested. (Continued)
