Termékáttekintés

The LMV431AIMF/NOPB is a 1.24V Precision Shunt Regulator, capable of adjustment to 30V. Negative feedback from the cathode to the adjust pin controls the cathode voltage, much like a non-inverting operational amplifier configuration. A two-resistor voltage divider terminated at the adjust pin controls the gain of a 1.24V band-gap reference. Shorting the cathode to the adjust pin (voltage follower) provides a cathode voltage of a 1.24V. It has respective initial tolerances of 1.5, 1 and 0.5% and functionally lend themselves to several applications that require zener diode type performance at low voltages. Applications include a 3 to 2.7V low drop-out regulator, an error amplifier in a 3V off-line switching regulator and even as a voltage detector. These parts are typically stable with capacitive loads greater than 10nF and less than 50pF.
  • Low-voltage operation/wide adjust range (1.24/30V)
  • Temperature compensated for industrial temperature range (39PPM/°C for LMV431AI))
  • Low operation current (55µA)
  • Low output impedance (0.25R)
  • Fast turn-on response
  • Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
