PMIC - Voltage Reference

LM4040A50IDBZT is a low power low dropout voltage reference with a maximum temperature coefficient of 30 ppm/ °C. LM4040 series voltage references are intended for operation from very low input voltages (1.1V) and can provide very precise lower voltages relative to the input. These voltage references feature a maximum low line current of 70µA and an output voltage of +2.5V (2.495V to 2.505V).

In the LM4040A50IDBZT application field and working principle, the operating principle of the LM4040A50IDBZT voltage reference is based on two internal zener diodes. The first zener diode provides the active regulation, while the second zener diode provides the static reference. The static reference is established and the active regulation adjusts both voltage and current over the input voltage and temperature range. The dynamic regulation uses the internal reference in order to minimize the supply current in order to maintain high accuracy.
