Integrated Dual LDO And Low-Dropout LED Driver LN5081 ■ General Description The LN5081 series of internal integration of two highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The device used in portable electronic products drive main or vice screen backlight modules and the provision of low-voltage system voltage source. LN5081 can drive six LEDs, each LED currents up to 20mA, through the PWM signal can adjust average brightness ,the constant current can also be adjusted by A one-time input pulse count signal, a total of 16 level linear cueent. LN5081 integrated two voltage regulator has a separate enable pin, and each one voltage regulator can be adjusted independently through the repair of the output voltage, voltage output range of 1.
