LX432 General Description
Low voltage operation enables the LX432 to be used in the feedback loop of isolated low voltage power supplies.
The minimum output voltage is determined by the LX432 output voltage plus the forward voltage drop of the opto-coupler LED (typically 1.24 + 1.4 = 2.64V minimum). See Figure 10. The LX432 is offered in 3 and 5-pin SOT-23 or TO-92 packages, and is a dropin replacement for the TLV431 and SC431L devices.
The LX432 series are low-voltage precision adjustable shunt regulators with a reference voltage of 1.24V. The output voltage may be set to any value between 1.24V and 20V by two external resistors.
These devices offer low output impedance for improved load regulation - typical output impedance is 250mΩ. The LX432 series operates with an operating current as low as 80µA, making these devices suitable for portable and micropower applications.
