LA5312V
Variable Divided Voltage Generator for LCDs
Overview
The LA5312V is a variable divided voltage generator IC for
multiple drive of LCD matrix.
Features
. Power supply for variable bias LCD drive
. (1/5 to 1/19 bias available by internal resistors)
Four voltage outputs generated by four operational
amplifiers.
. Low current drain (0.18 mA typ.)
. Miniflat package for miniaturization.

The output load resistor values (R1 to R8) are set so that when an ‘‘on’’ level signal is input to inputs 1 and 2, a current of 15 to
30 mA max. flows to the sink side and the source side (approximately 2 mA on the V1 source side).
Input 1
Input 2
STR Pin Usage
Start-up
circuit
The STR input is configured as shown left.
. The STR is either shorted with VCC or connected
. to VCC via an external resistor.
It is possible to use a separate power supply
(VIN) such that 2 V < VIN < VCC for current
saving.
(2 V or more required for STR)
(2 V < VIN < VCC)
