Frequently Asked Questions
What input voltage range does TLV70233QDBVRQ1 support?
TLV70233QDBVRQ1 accepts an input voltage from 3.8 V to 5.5 V, with an absolute maximum rating of 6 V. This range makes it directly compatible with 5 V system rails and single-cell Li-ion batteries discharging through a boost stage, covering the majority of automotive low-voltage subsystem supply scenarios.
How does the 35 µA quiescent current benefit always-on automotive modules?
With only 35 µA of quiescent current, TLV70233QDBVRQ1 draws minimal power when the load is light or the system is in standby, which is essential for always-on automotive modules such as keyless-entry receivers and telematics units powered directly from a 12 V-derived 5 V rail. This low-Iq characteristic extends battery standby time and reduces thermal dissipation across the full -40°C to 125°C operating temperature range.
For which automotive safety standard is TLV70233QDBVRQ1 qualified, and what does that mean for designers?
The device is qualified to AEC-Q100 Grade 1, covering the -40°C to 125°C junction temperature range required for harsh automotive environments. This qualification ensures the 300 mA LDO has passed stress testing for electrostatic discharge, moisture sensitivity, and high-temperature operating life, reducing qualification effort for Tier 1 automotive suppliers integrating the part into ADAS, body control, and infotainment power trees.
What is the typical dropout voltage of TLV70233QDBVRQ1 at full load?
At 300 mA output current, TLV70233QDBVRQ1 has a nominal dropout voltage of 0.22 V and a maximum of 0.375 V, so a 3.675 V or higher input is sufficient to maintain regulation. This low dropout characteristic is particularly valuable when the input rail sags near the output voltage level, such as at end-of-discharge on a 3.7 V Li-ion cell or during cold-crank transients on an automotive supply.
