SS431/G

Adjustable Precision Shunt Regulator

DESCRIPTION

FEATURES

Low voltage operation (2.5V)

The SS431 is a low-voltage three-terminal adjustable shunt

regulator with a guaranteed thermal stability over the applicable

Adjustable output voltage from VO = V REF to 18V

Wide operating current range from 0.4mA to 100mA

temperature range. The output voltage can be set to any value

between V_REF(approximately 2.5V) to 18V with two external

resistors (see application circuit). This device has a typical output

impedance of 0.2 ohms. Active output circuitry provides very sharp

turn-on characteristics, making this device an excellent

replacement for Zener diodes in many applications.

Low dynamic output impedance 0.5Ω max.

ESD rating is 5.5kV (per MIL-STD 883D)

Pb-free lead finish available.

APPLICATIONS

Linear Regulators

Adjustable Supplies

Switching Power Supplies

Battery Operated Computers

Instrumentation

The SS431 is characterized for operation from 0°C to 105°C,

and three package options (SOT-23, SOT-89, and TO-92) allow

the designer the opportunity to select the proper package for his

application. The SS431 is available with a Pb-free lead finish

Computer Disk Drives

- order as SS431Gxx.
