EC49513A/L-300mA Linear Regulator With Enable
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 chargefast. The device operates in the input voltage range from +2.2V to +7.0V and delivers 300mAoutput 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 passtransistor, and an enable/disable logic circuit. Otherfeatures include soft start function, short circuit protection, and thermal shutdown protection.
The EC49513A/L is also compatible with low ESR ceramic capacitors which give addedoutput 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.
