LN9305 source equivalent, 5 channel low dropout current source.
* Ultra low 60mV dropout at 20mA
* 3% high accuracy current matching
* 20mA full scale current
* PWM brightness control
* 2.5V to 5.5V supply voltage .
significantly improved efficiency. The LN9305 requires a 60mV dropout at a 20mA load on each output to match the LED br.
The LN9305 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The LN9305 uses a internal resistor to set the bias current for five LEDs, which are matched t.
