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 sub-
miniature (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.
