產品介紹
DescriptionThe JF2106 series is a CMOS-based positive low-dropout linear regulator (LDO) featuring 500mA/ 1.0A that provides high PSRR, high output voltage accuracy, fast load regulation,low-noise and low supply current.
It consists of a voltage reference, an error amplifier, a resistorladder for output voltage setting. It also has under-voltagelockout (UVLO), over current/short circuit protection circuitand over temperature shutdown circuit.
The JF2106 typically has 90mV dropout voltage at 500mAload current with VOUT=1.8V and 180mV dropout voltage at 1Aoutput current with VOUT=1.8V, and chip enable function (EN)for long battery life.
Excellent ripple rejection, load transient and line transientresponse make it ideal for the power sources of mobile
communication devices or camera modules in low lightcondition. It can also turn on under full load condition, makingit suitable for harsh system environment.
The JF2106 series LDOs have option for output current limitbetween 1.0A or 500mA by alternating the LCON pin between“H” or “L” for DFN1216-8L package version.
