低电压可调精密并联稳压器 LOW VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS
Features:
• Low Voltage Operation: 1.24V Reference
• Initial Voltage Reference Accuracy 1%
• Adjustable Output Voltage From V REF To 20V
• Typical Output Dynamic Impedance Less Than 250mOhm
• Sink Current Capability 80µA To 20mA
• Direct Alternative To TLV431 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 250mOHM. The LX432 series operates with an operating current as low as 80µA, making these devices suitable for portable and micropower applications. 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. The LX432 is offered in 3 and 5-pin SOT-23 or TO-92 packages, and is a drop-in replacement for the TLV431 and SC431L devices.
