1 / 13 page EC49121 600mA LDO with Fast Enable And Fast Discharge Function E-CMOS Corp. (www.ecmos.com.tw) Page 1 of 13 2009/01/12-2 Description The EC49121 series is a Low dropout linear regulator with ON/OFF control and EC49121 can discharge output capacitor charge fast. The device operates in the input voltage range from +2.4V to +7.0V and delivers 600mA output current. The EC49121 is available in two types, fixed output voltage type and adjustable output voltage type. The fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.2V, 1.5V, 2.85V, 3.0V and 3.6V are available by special order only. The output voltage range of the adjustable type is from 1.2V to 5V. The EC49121 (ADJ type) consists of a 1.175V band gap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection The EC49121 (Fixed type) consists of a 0.95V band gap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection, the fixed type version has fast respond and discharge feature. The EC49121 series devices are available in SOT-23-5L,TSOT-23-5L, SC-70-5L packages.
