AS4041

AS4041 Precision Micropower 1.24V Shunt Voltage Reference FEATURES APPLICATIONS Low temperature coefficient 50 ppm/°C Operating current range 100µA to 15 mA Low power, 250 mW @ IIN =100 mA Two terminal "Zener" operation www.DataSheet4U.com Small package: SOT - 23, TO-92, and SO-8 Fixed reverse breakdown voltage 2.5 Volt No output capacitance required Output voltage tolerance ± 0.5% Constant Current Source Digital Voltmeter Power Supply Monitor Precision Regulators Battery-Powered Equipment Instrumentation Automotive Electronics Data Acquisition Systems Energy Management PRODUCT DESCRIPTION The AS4041 is a two-terminal, temperature compensated, band-gap voltage reference, which provides a fixed 1.24V output for input currents between 500 µA to 5mA. The bandgap voltage (1.24V) is independently laser trimmed from the output voltage to achieve a very low tempco, then the output voltage is laser trimmed to 1.24 volts. This trimming technique and the low tempco (A grade 50 ppm/ °C) thin film resistor process gives a very stable device over the full temperature range. The AS4041 is available in the subminiature (3mm × 1.3mm) SOT-23, SO-8 surface mount package, or TO-92 package. The operating temperature is -40°C to 85°C. The ALPHA Semiconductor AS4041 advanced design eliminates the need for an external stabilized capacitor while insuring stability with any capacitive load, making them easy to use.
