*1: VIN (max) and IO (max) are restricted by the relation PD = (VIN - VO) × IO.
Calculate these values referring to the reference data on page 69.
*2: Refer to the Dropout Voltage parameter.
*3: For the SI-3012LU, set the input voltage to Vin ≥ 2.4 V, and secure the minimum voltage as explained in "Setting DC Input Voltage" section in Linear Regulator Application Note.
(Ta=25°C)
Surface-Mount, Low Current Consumption, Low Dropout Voltage
SI-3000LU Series
■Electrical Characteristics
(Ta=25°C, VC=2V, unless otherwise specified)
*1: Is1 is specified at the 5% drop point of output voltage VO on the condition that VIN = 3.3 V, and IO = 10 mA.
*2: Output is OFF when the output control terminal (VC terminal) is open. Each input level is equivalent to LS-TTL level. Therefore, the device can be driven directly by LS-TTLs.
