“Absolute Maximum Ratings” indicate limits beyond which damage to the component may occur.
Electrical specifications do not apply when operating the device outside of its rated operating
conditions.
The ESD rating of pins 3 and 4 for the SOT-23-5L package, or pins 5 and 2 for the micro SMD
package, is 1kV.
The maximum allowable power dissipation is a function of the maximum junction temperature,
TJ(MAX), the junction-to-ambient thermal resistance, ΘJ-A, and the ambient temperature, TA. The
maximum allowable power dissipation at any ambient temperature is calculated using:
Note 4:
Note 5:
Note 6:
Note 7:
Note 8:
Note 9:
Note 10:
Where the value of ΘJ-A for the SOT-23-5L package is 220°C/W in a typical PC board mounting and
the micro SMD package is 225°C/W. Exceeding the maximum allowable dissipation will cause
excessive die temperature, and the regulator will go into thermal shutdown.
If used in a dual-supply system where the regulator load is returned to a negative supply, the
GS2615 output must be diode-clamped to ground.
The output PNP structure contains a diode between the VIN to VOUT terminals that is normally
reverse-biased. Reversing the polarity from VIN to VOUT will turn on this diode.
Limits are 100% production tested at 25°C. Limits over the operating temperature range are
guaranteed through correlation using Statistical Quality Control (SQC) methods. The limits are used
to calculate National’s Average Outgoing Quality Level (AOQL).
Dropout voltage is defined as the input to output differential at which the output voltage drops 100
mV below the value measured with a 1V differential.
The ON/OFF input must be properly driven to prevent possible mis-operation. For details, refer to
Application Hints.
The GS2615 has foldback current limiting which allows a high peak current when VOUT>0.5V, and
then reduces the maximum output current as VOUT is forced to ground (see Typical Performance
Characteristics curves).
Exposing the micro SMD device to direct sunlight will cause mis-operation. See Application Hints for
additional information.
