12-3.Difinition of term
Characteristics
! Output Voltage (V
Out)
The output voltage is specified with VIn=VOut,TYP+1V and
IOut=5mA.
! Output Current (I
Out)
Output current, which can be used continuously (It is the
range where overheating protection of the IC does not
operate).
! Maximum output current (I
Out,Max)
The rated output current is specified under the condition
where the output voltage drops 0.9V times the value
specified with IOut=5mA by increasing the output current.
The input voltage is set to VOutTYP+1V and the current is
pulsed to minimize temperature effect.
! Dropout Voltage (V
Drop)
It is the difference between the input voltage and the
output voltage when the circuit stops the stable operation
by decreasing the input voltage. It is measured when the
output voltage drops 100mV from its nominal value by
decreasing the input voltage gradually.
! Line Regulation (LinReg)
It is the fluctuations of the output voltage value when the
input voltage is changed.
! Load Regulation (LoaReg)
It is the fluctuations of the output voltage value when the
input voltage is assumed to be VOut,TYP+1V, and the
output current is changed.
! Ripple Rejection (RR)
Ripple rejection is the ability of the regulator to attenuate
the ripple content of the input voltage at the output. It is
measured with the condition of VIn=VOut,TYP+1.5V. Ripple
rejection is the ratio of the ripple content between the
output vs. input and is expressed in dB
! Standby Current (I
Standby)
Standby current is the current which flows into the
regulator when the output is turned off by the control
function (VCont=0V).
Protections
! Over Current Protection
It is an function to protect the IC by limiting the output
current when excessive current flows to IC, such as the
output is connected to GND, ets.
! Thermal Protection
It protects the IC not to exceed the permissible power
consumption of the package in case of large power loss
inside the regulator. The output is turned off when the
chip reaches around 145°C, but it turns on again when the
temperature of the chip decreases.
! ESD
MM: 200pF 0
200V or over
HBM: 100pF 1.5k
2000V or over
