The document introduces the LM134 series products, which can be used as current source, temperature sensor, micro power bias network, etc.
The LM134 series from Linear Technology is a three‑terminal current source that can operate from 1 pA up to 10 mA, with a typical regulation of 0.02 %/V and an operating voltage range of 0.8 V to 40 V. Because the output current is proportional to absolute temperature, the device also serves as a highly linear temperature sensor with a temperature coefficient of 0.336 %/°C at room temperature.
The document provides absolute maximum ratings, package options (TO‑46 metal can and 8‑lead plastic SOT), detailed electrical characteristics, typical performance graphs, and a variety of application circuits such as remote temperature sensing, current limiting, and bias networks. Design notes cover start‑up bias currents, lead resistance effects, and shunt capacitance trimming for high‑precision use.
