The switch is controlled by a single On/Off logic input (non-inverting) and does not require a separate Vcc supply — the gate drive is derived from the load voltage. A status flag output reports overcurrent or overtemperature faults to the host controller. ## 95 mOhm Rds(on) and thermal budget in a SOT-23-5 With a typical on-resistance of 95 mOhm at 5 V input, the TPS2051BDBVTG4 dissipates under 25 mW at 500 mA load — low enough that the SOT-23-5 package (SC-74A, also designated SOT-753) stays within its thermal limits without a copper pour heatsink. The 1:1 input-to-output ratio means the switch passes the full input voltage to the load when enabled, with only the Rds(on) drop. For a 3.3 V rail at 500 mA, expect about 3.25 V at the output — enough margin for most USB and peripheral loads.","metaTitle":"TPS2051BDBVTG4 High-Side Power Switch, 95 mOhm, SOT-23-5","metaDescription":"TI TPS2051BDBVTG4 high-side power switch: 500 mA output, 95 mOhm Rds(on), fault protection, -40°C to 125°C.
