Electrical Characteristics
(Contd.)
Notes:
4. All limits at operating temperature extremes are guaranteed by design, characterization and statistical quality control.
5. AC specifications guaranteed by design/characterization (not production tested).
6. For a case when V
is higher than the typical 5V V
CC
. Voltage observed at V
CC
pin when the internal shunt regulator is sinking
current to keep voltage on V
CC
pin constant.
7. Test Conditions: V
LDO_IN
= 1.5V and V
LDO_OUT
= 1.2V
Unless otherwise noted, V
= 5V, T
= 25°C, using circuit in Figure 1.
The ‘
’ denotes that the specifications apply to the full ambient operating temperature range. See Notes 4 and 5.
