Datasheet Taiwan Semiconductor TS432BIX

TS432xIX
Taiwan Semiconductor 1.24V Programmable Shunt Voltage Reference
DESCRIPTION FEATURES The TS432AIX and TS432BIX is a three-terminal ● Precision Reference Voltage adjustable shunt regulator with specified thermal TS432AI - 1.24V±1% stability. The output voltage may be set to any value TS432BI - 1.24V±0.5% between VREF (approximately 1.24V) and 18V with two ● Minimum cathode current: 20µA(typ.) external resistors. The TS432AIX and TS432BIX has a ● Equivalent full range Temp. coefficient: 50ppm/ºC typical output impedance of 0.05Ω. Active output ● Programmable output voltage up to 18V circuitry provides a very sharp turn-on characteristic, ● Fast turn-on response making the TS432AIX and TS432BIX excellent ● replacement for zener diode in many applications. Sink current capability of 80µA to 100mA ● Low dynamic output impedance: 0.2Ω ● Low output noise ● Compliant to RoHS Directive 2011/65/EU and in
accordance to WEEE 2002/96/EC ● Halogen-free according to IEC 61249-2-21 APPLICATION
● SMPS ● Lighting ● Telecommunication ● Home appliance SOT-23
