Frequently Asked Questions
How low is the dropout voltage of TPS73201DRBT, and why does it matter for Li-ion battery designs?
TPS73201DRBT has a typical dropout of only 40 mV and a maximum of 150 mV at full load. This near-zero dropout is critical for single-cell Li-ion applications, where the battery voltage can fall to 3.0 V late in discharge, allowing the regulator to maintain a 2.8 V or higher output rail until the battery is nearly exhausted—extending useful runtime by 10% to 15% compared to 300 mV dropout alternatives.
What external resistors set the output voltage of TPS73201DRBT, and what is the reference voltage?
TPS73201DRBT uses two external feedback resistors connected to the ADJ pin. The internal reference voltage is typically 1.21 V. Selecting a 100 kΩ feedback resistor to ground and calculating the top resistor using V_out = 1.21 V × (1 + R1/R2) lets designers set any output from around 1.21 V up to 5.5 V, making the device flexible across 1.8 V, 2.5 V, 3.0 V, and 3.3 V digital rails.
How does TPS73201DRBT compare to a fixed-output LDO for a 3.3 V design with tight board space?
TPS73201DRBT fits in an 8-pin SON package measuring approximately 2 mm × 2 mm, comparable to fixed-output LDOs in SOT-23. The adjustable version lets one SKU replace multiple fixed-voltage variants, reducing inventory. Its 0.01 %/V line regulation at 1.7 V to 5.5 V input competes directly with fixed 3.3 V LDOs used in microcontroller and sensor power rails.
