EMP8100-1.5A Adjustable&Fixed Voltage LDO


EMP8100-1.5A Adjustable&Fixed Voltage LDO DataSheet

General Description
    The EMP8100 series is a CMOS low-dropout linear regulator that operates in the input voltage range from +2.5V to +6.5V and delivers 1.5A output current.
    The EMP8100 is available 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 EMP8100 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 EMP8100 series devices are available in both of SOT-223 and TO-252 packages.
