DESCRIPTION
The M62230FP is a semiconductor circuit for LCD matrix regulator,
which will generate the diveded-voltage to drive LCD matrix.
By changing the connection of R pin(i.e.,Change the internal
resistor ratio), M62230FP can support divided voltage ratio ranging
from 1/5 bias to 1/13 bias.
The high stability and any desired voltage levels is possible, since
the variable voltage regulator for Vref is built-in.
FEATURES
Adjustable type voltage divider.
(The setting range of internal resistor is from 1/5 bias to 1/13
bias)
5 resident buffer-Amp. (5 divided output)
Low power dissipation(1.8 mA Typ.)
Resident voltage-variable regulator for Vref.
APPLICATION
To drive LCD.
