LN5081
Overview
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.
- 6 roads of 20mA current source can be used as main or Vice LED Driver
- PWM average current Control
- Single-wire interface configuration, 16 Level Linear Current Brightness Control
- Ultra Low LED Dropout: 200mV at 20mA (TYP)
- Dual 300mA Linear Regulators
- 1.3V to 6V output Voltage Range, stepping to 0.05 V
- High output voltage accuracy up to ± 2.0%
- LDO input and output low dropout voltage, 200 mV typical (3.0V output, IOUT = 100mA)
- Maximum output current up to 300mA (VIN ≥ VOUT +1 V) VIN_LDO 5 VOUTA 6
- Standby current is less than 0.1μA
