EMP8090-1A Adjustable&Fixed Voltage LDO DataSheet

General Description
    The EMP8090 series is a low-dropout linear regulator that operates in the input voltage range from +2.5V to +6.5V and delivers 1.0A output current.
    The EMP8090 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 1.25V to 5V.
    The EMP8090 (ADJ type) consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection.
    The EMP8090 (Fixed type) 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 EMP8090 series devices are available in SOT-223 and TO-252 packages.
