TL1093L-AB3-R

UNISONIC TECHNOLOGIES CO., LTD TL1093 PROGRAMMABLE PRECISION REFERENCE DESCRIPTION The UTC TL1093 is a three-terminal adjustable regulator with a guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5V) and 36 V with two external resistors. It provides very wide applications, including shunt regulator, series regulator, switching regulator, voltage reference and others. LINEAR INTEGRATED CIRCUIT 1 FEATURES *Programmable output Voltage to 36V. *Low dynamic output impedance 0.2Ω. *Sink current capability of 1.0 to 100mA. *Equivalent full-range temperature coefficient of 50ppm/ °C typical for operation over full rated operating temperature range.
