description

The TL430 is a 3-terminal adjustable shunt
regulator, featuring excellent temperature
stability, wide operating current range, and low
output noise. The output voltage can be set by two
external resistors to any desired value between
3 V and 30 V . The TL430 can replace zener diodes
in many applications, providing improved
performance.

The TL430C is characterized for operation from
0°C to 70°C.

†

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values are with respect to the anode terminal.

2. Maximum power dissipation is a function of TJ(max),
ambient temperature is PD = (TJ(max) – TA)/

3. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
