Note 2:
Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed through
correlation using standard quality-control (SQC) methods.
Note 3:
Pulse tested at V
IN
= 28V, I
LOAD
= 30mA to avoid exceeding package power-dissipation limits.
Note 4:
Guaranteed by design. Tested with V
OUT
set to 5V. Dropout voltage is tested by reducing the input voltage until V
OUT
drops
to 100mV below its nominal value, measured with V
IN
starting 2V above V
OUT
.
Note 5:
Use at least 1μF minimum for light loads. Add 0.125μF/mA (0.2μF/mA for the MAX1616) for loads greater than 100μA,
not production tested. See Capacitor Selectionin the Applications Informationsection.
