LA5312V
Maximum Output Current Load Test Conditions
Input 1
Input 2
V_CC – V_EE = 35 V
R_X = 8 R
C1 to 4 = 10 µF
C5 = 33 µF
TR1 to 4: 2SA984 E or F rank
TR5 to 9: 2SC2274 E or F rank
R: 1 W or more
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
(V_IN) such that 2 V < V_IN < V_CC for current
saving.
(2 V or more required for STR)
(2 V < V_IN < V_CC)
