AZ431L
LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Features
The AZ431L series ICs are low voltage three-terminal adjustable
regulators with guaranteed thermal stability over a full operation
range. These ICs feature sharp turn-on characteristics, low
temperature coefficient and low output impedance, which make them
ideal substitutes for Zener diodes in applications such as switching
power supply, charger, motherboard and other adjustable regulators.
Wide Programmable Precise Output Voltage from 1.24V to 18V
High Stability under Capacitive Load
Low Temperature Deviation: 3mV Typical
Low Equivalent Full-range Temperature Coefficient: 20PPM/oC
Typical
Low Dynamic Output Resistance: 0.05Ω Typical
High Sink Current Capacity from 0.1mA to 100mA
Low Output Noise
The output voltage can be set to any value between 1.24V and 18V
with two external resistors.
Wide Operating Range of -40 to +125oC
The AZ431L precision reference is offered in two voltage tolerance:
0.5% and 1.0%.
These ICs are available in 4 packages: TO-92 (bulk or ammo
packing), SOT-23, SOT-23-5 and SOT-89.
