LOW VOLTAGE (1.25V) ADJUSTABLE PRECISION SHUNT REGULATOR
AZ432
General Description
Features
The AZ432 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
1.25V to 18V
High Stability under Capacitive Load
Low Temperature Deviation: 3mV Typical
Low Equivalent Full-Range Temperature Coeffi-
·
·
·
o
cient: 20PPM/ C Typical
·
·
Low Dynamic Output Resistance: 0.05Ω Typical
High Sink Current Capacity from 0.1mA to 100
mA
The output voltage can be set to any value between
1.25V and 18V with two external resistors.
·
·
Low Output Noise
o
Wide Operating Range of -40 to 125 C
The AZ432 precision reference is offered in two volt-
age tolerance: 0.5% and 1.0%.
Applications
These ICs are available in 4 packages: TO-92 (bulk or
ammo packing), SOT-23, SOT-23-5 and SOT-89.
