TPS2051CDBVR

Texas Instruments · AC-DC Controllers and Regulators · SOT-23-5

TPS2051CDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Power-switch output; connect to load. Sourced from IN through the internal high-side MOSFET when EN is asserted. Rated 0.5A continuous for TPS2051C.
2 GND power_in Device ground reference. All voltages are referenced to this pin.
3 FLT output Active-low open-drain fault output, asserted during overcurrent or overtemperature conditions. Requires an external pull-up resistor (typ. 10kΩ) to a logic supply. Sink current 0-5mA.
4 EN input Active-high enable input; logic high turns on the power switch. VIH ≥ 2V, VIL ≤ 0.7V; 0-5.5V input range. TPS2051C is the active-high variant (EN, not EN̄).
5 IN power_in Input voltage and power-switch drain (4.5-5.5V). Connect a 0.1µF or greater ceramic bypass capacitor from IN to GND close to the IC.
