Description

The M62230FP is a semiconductor circuit for LCD matrix regulator, which will generate the divided-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.

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 V

Application

To drive LCD.

Recommend Operating Conditions (Ta = 25
