Section 3 Electrical Characteristics

3.2.1.5 Regulator Characteristics

Conditions:

•

See

Section 3.2.1.1, Supply Voltage Characteristics.

Note 1.

The capacitors has to be mounted with one of the following connections:

- Distribute evenly the total capacitance for the device to all AWOVCL pins.

- Concentrate the total capacitance for the device to one AWOVCL pin.

In this case, the capacitor has to be connected to F23(BGA516),

A22(BGA373), A18(BGA292), 126(QFP176), A13(BGA156) and 103(QFP144).

And other AWOVCL pins which capacitor not connected has to be left open.

Note 2.

This is reference value.

Note 3.

When returning from DeepSTOP.

Note 4.

The time of current flow is less than 2.5 μs.
