FEATURES

s Low startup overshoot

s Wide current operation: 40

µA to 100mA

s Low temperature coefficient reference: +12mV

max deviation over temperature

s Accurate 1.24V reference voltage: +0.5%

(+6mV) at 25

°°°°°C

DESCRIPTION

The CAT431L is a low-voltage three-terminal

adjustable shunt voltage reference with guaranteed

thermal stability over the industrial temperature range.

The CAT431L has a lower 1.24V reference and wider

operating current range than the widely used TL431

and TL431A shunt-regulator references. Compared

to the TLV431/A, the CAT431L 1.24V reference is two

times more accurate.

CAT431L

Low-Voltage Adjustable Precision Voltage Reference

- 0.5% Tolerance

- SOT23 and TO92 Packages

- Low Startup Overshoot

s Low dynamic impedance: 0.3

Ω at 1kHz

s Compact 3-lead SOT23 package option

s Industrial temperature range: -40

°°°°°C to 85°°°°°C

s Adjustable output voltage: V

Doc. No. 4006, Rev. J

APPLICATIONS

s SMPS control loop

s Shunt regulator

s Low temperature coefficient voltage reference

s Current limiting

s Over/Under voltage monitor

s 3V Off-line switching regulators

Minimal overshoot at startup and wide AC bandwidth

make the CAT431L easy to apply in a wide set of

applications. When used with an opto-coupler, the

CAT431L is an ideal voltage reference in isolated

feedback circuits for 3V to 3.3V switch-mode power

supplies.
