1 Features 3 Description 1 The LMV431, LMV431A and LMV431B are precision • Low-Voltage Operation/Wide Adjust Range 1.24 V shunt regulators capable of adjustment to 30 (1.24 V/30 V) V. Negative feedback from the cathode to the adjust • 0.5% Initial Tolerance (LMV431B) pin controls the cathode voltage, much like a non- • Temperature Compensated for Industrial inverting op amp configuration (Refer to Symbol and Temperature Range (39 PPM/°C for the Functional Diagrams). A two-resistor voltage divider LMV431AI) terminated at the adjust pin controls the gain of a 1.24 V band-gap reference. Shorting the cathode to • Low Operation Current (55 µA) the adjust pin (voltage follower) provides a cathode • Low Output Impedance (0.25 Ω) voltage of a 1.24 V. • Fast Turn-On Response The LMV431, LMV431A and LMV431B have • Low Cost respective initial tolerances of 1.5%, 1%, and 0.5%, and functionally lend themselves to several 2 Applications applications that require zener diode type performance at low voltages. Applications include a 3 • Shunt Regulator V to 2.7 V low drop-out regulator, an error amplifier in • Series Regulator a 3 V off-line switching regulator and even as a • Current Source or Sink voltage detector. These parts are typically stable with capacitive loads greater than 10 nF and less than 50 • Voltage Monitor pF. • Error Amplifier The LMV431, LMV431A and LMV431B provide • 3-V Off-Line Switching Regulator performance at a competitive price. • Low Dropout N-Channel Series Regulator Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) LMV431 SOT-23 (5) 2.90 mm x 1.60 mm LMV431 TO-92 (3) 4.30 mm x 4.30 mm LMV431 SOT-23 (3) 2.92 mm x 1.30 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
