12. APPLICATIONS INFORMATION
12-1.Definition of term
Relating Characteristic
note Each characteristics will be measured in a short
period not to be influenced by joint temperature (Tj).
*Output voltage (Vout)
The output voltage is specified with Vin= VoutTYP+1V
and Iout=5mA
*Output current (Iout)
Output current, which can be used continuously (It is
the range where overheating protection of the IC does not
operate.)
*Peak output current (Iout
PEAK)
The rated output current is specified under the
condition where the output voltage drops 90% by
increasing the output current, compared to the value
specified at Vin=VoutTYP-1.5V.
*Dropout voltage (Vdrop)
It is an I/O voltage difference 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 output voltage value when the
input voltage is assumed to be VoutTYP -1.5V, and the
load current is changed.
*Ripple Rejection (R.R)
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-2.0V. Ripple rejection is the ratio of the ripple
content between the output vs. input and is expressed in
dB
*Standby current (Istandby)
It is an input current which flows to the control terminal,
when the IC is turned off.
Relating Protection Circuit
*Over Current Protection
It is a function to protect the IC by limiting the output
current when excessive current flows to IC, such as the
output is connected to GND, etc.
*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
150
°C, but it turns on again when the temperature of the
chip decreases.
*ESD
It is tested by connecting charged capacitor to GND
pin and Vin pin.
