Frequently Asked Questions
What is the dropout voltage of TPS76038DBVT at its maximum 50 mA output current?
The TPS76038DBVT has a typical dropout voltage of 120 mV and a maximum of 180 mV at 50 mA output current. This low dropout allows it to maintain a regulated 3.8 V output from a nearly depleted lithium-ion cell whose terminal voltage can fall to around 4 V, extending usable battery runtime significantly.
Can TPS76038DBVT operate directly from a 12 V automotive power rail?
Yes, TPS76038DBVT accepts input voltages from 4 V up to 16 V absolute maximum, making it fully compatible with 12 V automotive accessory power rails. The regulator absorbs the 12 V to 3.8 V differential while delivering up to 50 mA to downstream logic or sensor loads, with no external pass transistor required.
How compact is the TPS76038DBVT footprint for space-constrained PCB layouts?
The 5-pin SOT-23 package measures approximately 2.9 mm × 1.6 mm with a 0.95 mm pin pitch, occupying under 5 mm² of board area. This tiny footprint requires only two small bypass capacitors—typically 1 µF on input and 1 µF on output—keeping the total solution area below 10 mm² on most PCB designs.
For a battery-powered sensor node, how does TPS76038DBVT compare to a switching regulator in terms of noise?
As a linear regulator, TPS76038DBVT produces no switching noise, achieving output ripple well below 10 µV RMS compared to switching regulators that typically generate 10 mV to 50 mV peak-to-peak ripple. This low-noise characteristic makes it the preferred choice for RF circuits, ADC reference supplies, and audio front ends where switching harmonics degrade signal quality.
What output voltage does TPS76038DBVT supply and how is it set?
TPS76038DBVT provides a fixed factory-programmed output of 3.8 V with no external resistor divider required. The fixed output eliminates resistor tolerance errors and simplifies BOM management compared to adjustable LDOs. A 1 µF ceramic output capacitor ensures stable regulation across the full 50 mA load range.
