LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR
General Description
Features
AZ431L
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.
The output voltage can be set to any value between
1.24V and 18V with two external resistors.
The AZ431L precision reference is offered in two
bandgap tolerance: 0.5% and 1%.
· 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 Coeffi-
cient: 20PPM/oC Typical
· Low Dynamic Output Resistance: 0.05Typical
· High Sink Current Capacity from 55µA to 100
mA
· Low Output Noise
· Wide Operating Range of -40 to 125oC
Applications
These ICs are available in 4 packages: TO-92, SOT-
23-3, SOT-23-5, SOT-89.
