SOT23-3L SOT23-5L Description SOT323-6L
The TLVH431 is a low power adjustable shunt voltage reference, with guaranteed temperature stability over the entire operating temperature
Features
range. • Adjustable output voltage: 1.24 V to 18 V The output voltage may be set to any value • Low operating current: 100 µA at 25 °C between 1.24 V and 18 V by means of an external • resistor divider. 0.25%, 0.5%, 1% and 1.5% voltage precision • The TLVH431 operates with a wide current range Sink current capability up to 60 mA from 100 µA to 60 mA with a typical dynamic • -40 to +125 °C temperature range impedance of 0.22 Ω. • 100 ppm/°C maximum temperature coefficient Available in SOT23-3L, SOT23-5L and SOT323- • Available in SOT23-3L, SOT23-5L and 6L surface mounted packages, it can be designed SOT323-6L packages in applications where space saving is a critical issue.
Applications
The low operating current is a key advantage for • power restricted designs. Computers
