SUL6001S5-ADJ

The SUL6001 series is a CMOS-based positive low-dropout linear regulator (LDO) featuring 500 mA/ 1.0A that provides high PSRR, high output voltage accuracy, low-noise and low supply current. It consists of a voltage reference, an error amplifier, a resistor-ladder for output voltage setting. It also has under-voltage lockout (UVLO), over current/short circuit protection circuit and over temperature shutdown circuit. The SUL6001 typically has 95mV dropout voltage (DFN1216-8, lout =1A ，Vout =3.3V) and 156mA dropout voltage (DFN1216-8, lout =1A Vout =1.8V) and chip enable function (EN) for long battery life. Excellent ripple rejection, load transient and line transient response make it ideal for the power sources of mobile communication devices or camera modules in low light condition. It can also turn on under full load condition, making it suitable for harsh system environment. The SUL6001 series LDOs have option for output current limit between 1.0A or 500mA by alternating the LCON pin between “H” or “L” for DFN1216-8 package version.
