3.3V REGULATOR
A metal option provides for a alternate 3.30 VDC ±3%
at up to 50 mA of load current over the entire operating
temperature
range
of
-40°C
to
+125°C.
All
specifications given above for the 5.0V operation apply
except for any difference noted here.
The same input tracking of 4.25V applies the 3.3V
regulator.
FIGURE 1-10:
Voltage Regulator Output on POR.
Note:
The regulator has an overload current
limiting of approximately 100 mA. If VREG
is lower than 2.5V, the VREG will turn off.
Note 1:
Start-up, VBB < 5.75V, regulator off.
2:
VBB > 5.75V, regulator on.
3:
VBB
≤ 5.5V, regulator tracks VBB.
4:
VBB < 4.25V, regulator will turn off.
