*1: VIN (max) and IO (max) are restricted by the relationship PD = (VIN - VO) × IO.
Calculate these values referring to the reference data.
*2: Refer to the dropout voltage section.
*3: For the SI-3012LU, set the input voltage to at least 2.4 V, and secure the minimum voltage as explained in Setting DC Input Voltage,

*1: Is1 is specified as the 5% drop point of output voltage VO on the condition that VIN = 3.3 V (5 V for SI-3033LU, 6 V for SI-3050LU),
and IO = 10 mA.
*2: Output is OFF when the output control pin (VC pin) is open. Each input level is equivalent to that for LS-TTL. Therefore, the device can be
driven directly by an LS-TTL circuit.

• A monolithic IC is mounted.The inner frame stage is connected
to the GND pin (pin 2). Therefore, enlarging the copper lami-
nate area leading to the GND pin achieves a heat radiation
effect.

• How to calculate the junction temperature
Measure the temperature (TC) of the GND pin (pin 2) lead
section using a thermistor, etc. Substitute this value in the
following formula and calculate the junction temperature.
Tj=PD×θj–c+Tc (θj–c=5°C/W)
