1 / 24 page EC49513A/L 300mA Linear Regulator with Enable And Fast Discharge Function E-CMOS Corp. (www.ecmos.com.tw) Page 1 of 24 2010/10/29 Description The EC49513A/L is a 4-Low (Low dropout, Low quiescent Current, Low noise, Low cost) linear regulator with ON/OFF control and EC49513L can discharge output capacitor charge fast. The device operates in the input voltage range from +2.2V to +7.0V and delivers 300mA output current. The high accuracy output voltage is preset at an internally trimmed voltage 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V or 3.3V. Other output voltages can be mask optioned from 1.2V to 5.0V with 100mV increment, except the EC49513A/L-285 which has 2.85V output voltage. The EC49513A/L consists of a 1.0V reference compares amplifier, a P-channel pass transistor, and an enable/disable logic circuit. Other features include soft start function, short circuit protection, and thermal shutdown protection. The EC49513A/L is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the chip. The EC49513A/L devices are available in SOT23-5L、UFN-6 and TSOT23-5 packages. Features EC49513A/L Without / With Fast Discharge Operating Voltage Range:+2.2V to +7.0V Output Voltages:+1.2V to +5.0V with 100mV Maximum Output Current:300 mA Dropout Voltage:120mV @ 100mA Low Current Consumption 15μA (Typ.) Shutdown Current:0.1μA (Typ.) ±2% Output Voltage Accuracy (special ±1% highly accurate) Low ESR Capacitor Compatible High Ripple Rejection:70 dB Output Current Limit Protection (450mA) Short Circuit Protection (150mA) Thermal Overload Shutdown Protection Control Output ON/OFF Function SOT23-5L、UFN-6 and TSOT23-5 packages. Green (Halogen Free With Commercial Standard) Application Battery-Powered Devices. Personal Communication Devices. Mobile Phones, Cordless Phone. Portable Games. Portable AV equipment. |
