Electrical Characteristics table for the TCR2EF and TCR2EE Series

As an example, an "Electrical Characteristics" table for the TCR2EF and TCR2EE Series is shown below.

Definitions of the Terms in the Table

  1. Input voltage (VIN) :
    Absolute maximum voltage that can be applied between the input and GND
  2. Control voltage (VCT) :
    Voltage range over which an IC can be turned on and off
  3. Output voltage (VOUT) :
    Output voltage range that an IC can tolerate
  4. Output current (IOUT) :
    Maximum output current (load current) that can flow thru an IC
  5. Power dissipation (PD) :
    IMaximum power that the IC can dissipate. The PD value of a surface-mount device varies with pc board materials and land pad dimensions. The power dissipation (PD) of a low-dropout (LDO) voltage regulator can be calculated as follows:
    PD = VIN × IB +(VIN - VOUT)× IOUT
    where VIN is input voltage, VOUT is output voltage, IB is bias current and IOUT is output current.
  6. Operational temperature range (Topr) :
    The allowable ambient temperature range when the device is operating under a specified condition
  7. Junction temperature (Tj):
    Maximum junction temperature that the IC can tolerate
  8. Storage temperature (Tstg):
    Ambient temperature range in which the IC can be stored with no voltage applied
