AP431/AP431A

Adjustable Precision Shunt Regulator

Features

Description

• Precision reference voltage

AP431 : 2.495V ± 1%

The AP431/AP431A are 3-terminal adjustable

precision shunt regulators with guaranteed

temperature stability over the applicable extended

commercial temperature range. The output voltage

AP431A : 2.495V ± 0.5%

• Sink current capability: 200mA

• Minimum cathode current for regulation: 300μA

• Equivalent full-range temp coefficient: 30 ppm/^oC

• Fast turn-on response

may be set at any level greater than 2.495V(V_REF

)

up to 36V merely by selecting two external resistors

that act as a voltage divider network. These devices

have a typical output impedance of 0.2Ω. Active

output circuitry provides very sharp turn-on

characteristics, making these devices excellent

improved replacements for Zener diodes in many

applications.

• Low dynamic output impedance: 0.2Ω

• Programmable output voltage to 36v

• Low output noise.

• Packages: TO92, SOT89, SOT23, SOT25 and

SOP

The precise (+/-) 1% Reference voltage tolerance of

the AP431/431A make it possible in many

applications to avoid the use of a variable resistor,

consequently saving cost and eliminating drift and

reliability problems associated with it.
