1 / 16 page E-CMOS Corp. (www.ecmos.com.tw) Page 1 of 15 5L14N-Rev.F009 EC3111 300mA High-PSRR Low Dropout Voltage Linear Regulators General Description The EC3111 is a 300mA, low dropout and low noise linear regulator with high ripple rejection ratio and fast turn-on time. It has fixed output voltage ranging from 1.1V to 4.8V. The EC3111 includes a voltage reference unit,an error amplifier, resistor net for voltage setting,a current limit circuit and a chip enable circuit. These ICs perform with low dropout voltage and a chip enable function(SOT23-5L/TSOT23-5L/SC70-4L/ SC70-5L/DFN 6L package only). The EC3111 works well with low ESR ceramic capacitors, suitable for portable RF and wireless battery-powered applications with stringent space requirements and demanding performance. It also offers ultra low noise output and has low quiescent current. Function Block Diagram Features VIN Range: 2.0V to 6.0V Low Dropout Voltage: 0.22V (Typ) (VOUT= 3.3V, IOUT= 150mA) High Ripple Rejection: 65dB (Typ)(f=10kHz) Excellent Line Regulation: 0.01% / V(Typ) Output Voltage Accuracy: ±2.0% Low Supply Current: 25µA (Typ) Standby Current: 0.01µA (Typ) Over Current Protection Fixed Output Voltage: 1.1V ~ 4.8V Ultra Fast Transient Response Applications Portable Communication Equipment Battery-Powered Equipment |
