TX72XX General Description:
The TX72XX series is a group of positive voltage output, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved through CMOS and laser trimming technologies.
The TX72XX consists of a high-precision voltage reference, an error amplification circuit, and a current limited output driver. Transient response to load variations have improved in comparison to the existing series. SOT89 and SOT23-3 packages are available.
TX72XX Features:
Low voltage drop: 0.17V@100mA
High input voltage: 15V
Low temperature coefficient
Large Output Current: >0.35A
Low Quiescent Current: 1.5uA
Output voltage accuracy: tolerance ±2%
Built-in current limiter
SOT89 and SOT23-3 package
