TLV70312DBVR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TLV70312DBVR is a single-channel analog comparator from Texas Instruments, part of the TLV703x family. It features a fixed output voltage threshold of 1.2V and operates within a supply voltage range of 1.6V to 5.5V. The device draws a typical quiescent current of 400nA per channel. It provides a propagation delay of 1.8µs at 5V and a slew rate of 0.1V/µs. The component is housed in a 5-pin SOT-23 package (SC-74A) and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'G4' if environmental compliance documentation is required for your region. Confirm the package variant matches your PCB footprint requirements, as SOT-23 dimensions are critical for assembly. Ensure the input common-mode voltage range aligns with your signal levels relative to the supply rails. Check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.2V reference is sufficient for the application, avoiding the need for external precision resistors. Consider the TLV7031 series over adjustable variants if board space and bill-of-materials count are primary constraints. Evaluate the 1.8µs propagation delay against your signal frequency requirements to ensure adequate response time. Verify that the 400nA quiescent current meets the strict power budget of the target system.
