EC432L
Adjustable Precision Shunt Regulator
Descriptions
The EC432L is a low voltage three terminal adjustable shunt regulator with a guaranteed thermal stability over applicable
temperature ranges. The output voltage can be set to any value between VREF (approximately 1.24 V) to 8V with two
external resistors. This device has a typical output impedance of 0.30ꢀ. Active output circuitry provides a very sharp turn
on characteristic, making this device excellent replacement for Zener diodes in many applications.
The EC432L is characterized for operation from -40℃ to 105℃, and two package options (SOT-23 、SC59 and TO-92)
allow the designer the opportunity to select the proper package for their applications.
Feature
■ Low voltage operation (1.24V)
■ Adjustable output voltage V0 =VREF to 8V
■ Wide operating current range 60A to 100mA
■ Low dynamic output impedance 0.30ꢀ (Typ.)
■ Trimmed bandgap design up to + 0.5%.
■ ESD rating is 2.5KV(Per MIL-STD-883D)
■ 100% Lead (Pb)-Free.
Application
■ Linear Regulators
■ Adjustable Supplies
■ Switching Power Supplies
■ Battery Operated Computers
■ Instrumentation
■Computer Disk Drives

The areas under the curves represent conditions that may cause the device to oscillate. For VKA = 2V and 3V curves, R2
and VBAT were adjusted to establish the initial VKA and I conditions with CL = 0. VBAT and C then were adjusted to
determine the ranges of stability. As the graph suggested, EC432L is unconditional stable with I from 0 to 100mA and
with C from 0.001uF to 1uF.
