The key to this breakthrough is the use of EEPROM registers for correction of curvature, temperature coefficient (tempco), and accuracy on a CMOS band-gap architecture allowing package-level programming to overcome assembly shift.
The shifts in voltage accuracy and tempco during assembly of die into plastic packages limit the accuracy of references trimmed with laser techniques.
Unlike other LDO references, the LM4132 can deliver up to 20 mA and does not require an output capacitor or buffer amplifier.
These advantages along with the SOT-23 packaging are important for space-critical applications.
Series references provide lower power consumption than shunt references, because they do not have to idle the m...
