Product details

The Texas Instruments TPS72201DBVR is a single-output, adjustable positive LDO regulator rated for 50 mA continuous output. The enable pin lets you shut down the output for power sequencing or sleep modes, and the built-in protection covers over-current, over-temperature, and reverse polarity — useful when the input rail might see a miswired battery or a hot-swap glitch.

PSRR and ripple rejection

The 48 dB PSRR at 100 Hz tells you this LDO knocks down line-frequency ripple. If your input comes from a rectified AC supply or a switching pre-regulator with 100/120 Hz ripple, the TPS72201DBVR cleans it up enough for many analog and RF bias rails. Not a high-PSRR part for sensitive audio or precision ADC supplies, but adequate for general-purpose low-noise rails.

Frequently asked questions

Is TPS72201DBVR suitable for battery-powered devices?

Yes, for low-current loads. The 50 mA output and 0.1 V dropout make it a good fit for powering a sensor, a small MCU in sleep mode, or an analog front-end from a single-cell Li-ion or two-cell alkaline pack. The quiescent current of 120 µA is reasonable for always-on rails, though not the lowest in its class.

What are the equivalent parts to TPS72201DBVR?

Pin-compatible alternatives within the same TI family include the TPS72201DBVT (same die, Tape & Reel variant) and the fixed-output versions TPS72218DBVR (1.8 V) and TPS72225DBVR (2.5 V). For a higher-current drop-in, the TPS72701DBVR offers 300 mA in the same SOT-23-5 footprint but with a different pinout — verify before substituting.
