Description

The TLV3691 offers a wide supply range, low quiescent current 150 nA (maximum), and rail-to-rail inputs. All of these features come in industry-standard and extremely small packages, making this device an excellent choice for low-voltage and low-power applications for portable electronics and industrial systems.

Available as a single channel, the low-power, wide supply, and temperature range makes this device flexible enough to handle almost any application from consumer to industrial. The TLV3691 is available in SC70-5 and 1-mm × 1-mm DFN-6 packages. This device is specified for operation across the expanded industrial temperature range of –40°C to 125°C.
