At this frequency the switching losses are manageable for a 500 mA load, and the output ripple stays within 20–30 mV peak-to-peak with a 10 µF ceramic output cap.
Rated for 500 mA continuous output, this part suits low-power rails like sensor supplies, MCU I/O banks, or auxiliary bias lines.
Yes, the TPS62102D is pin-compatible with the TPS62101. Both are in the same 8-SOIC footprint and share the same pinout — the difference is the output current rating: the TPS62101 is rated for 300 mA, while the TPS62102D delivers 500 mA.
Yes. The output is adjustable from 0.8 V to 8 V, so setting the feedback resistor divider for 3.3 V is straightforward. The 1 MHz switching frequency and 500 mA capability make it a clean fit for a 3.3 V rail powering an MCU or small FPGA.
