CXT-STA4919- Preliminary Datasheet High-Temperature Automotive Adjustable, Linear Voltage Regulator +3.0V to +28V
■CXT-STA4919 is part of the new CXT series of components designed and qualified for high-temperature automotive environments.
■It is a high-temperature, high-reliability,50mA adjustable linear voltage regulator suitable to generate from a +4.5V to +30V voltage source any regulated voltage in the range +3.0V to +28V. Its operating junction temperature ranges from -40°C to +175°C, in excess of AEC-Q100 Grade 0 automotive qualification standard. The regulator is self-protected with a built-in current limiter and a thermal protection. CXT-STA4919 brings unique benefits in applications where the ambient or operating temperature is high and above the temperature supported by traditional semiconductors.
■The IC features a chip-enable (CE active low) input signal allowing placing the circuit in low-power, disable mode.
■The output voltage is adjustable by an external feedback resistor network.
■CXT-STA4919 is available in a tiny plastic package PSOIC8 with exposed pad for small PCB footprint and low thermal resistance.
