EC8815 – 1.5A Fixed Voltage LDO Linear Regulator

General description

The EC8815 series is a CMOS low-dropout linear regulator that operates in the input voltage range from +2.4V to +7.0V and delivers 1.5A output current.The EC8815 is available fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.0V, 1.2V, 1.5V, 2.85V, 3.0V and 3.6V are available by special order only.The EC8815 consists of a 0.95V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The EC8815 series devices are available in SOT-223, TO-252 and TO-263 packages.
