WSL432 Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – Adjustable Precision Shunt Regulator

WSL432
Adjustable Precision Shunt Regulator
Features
• Precise Reference Voltage to 1.240V
• Guaranteed 1% and 1.5% Reference Voltage
Tolerance
• Sink Current Capability, 0.1mA to 20mA
• Quick Turn-on
• Adjustable Output Voltage, Vo = Vref to 6V
• Low Operational Cathode Current, 42µA
Typical
• 0.1Ω Typical Output Impedance
• TO-92 and SOT-23 Package
This device has a typical output impedance of
0.1Ω. Active output circuitry provides a very
sharp turn-on characteristic, making the
WSL432 excellent replacements for zener diodes
in many applications, including on-board
regulation and adjustable power supplies.
Applications
• Linear Regulators
• Adjustable Power Supply
• Switching Power Supply
General Description
The WSL432 is a 3 terminal adjustable voltage
reference with specified thermal stability over
applicable commercial temperature ranges.
Output voltage may be set to any value between
Vref (1.24V) and 6V with two external resistors
(see Figure 2).
When used with a photo-coupler, the WSL432 is
an ideal voltage reference in isolated feedback
circuits for 1.24V to 6V switching-mode power
supplies.
