The TPS7A0233DBVR: Fixed 3.3 V output, 200 mA LDO. Quiescent current is 60 nA. PSRR is 55 dB at 1 kHz.
Includes enable pin, over-current, over-temperature, and UVLO protection.
5-pin SOT-23-5 package. Dropout voltage is 0.31 V max at 200 mA.
Product status is Active. ROHS3 compliant.
The quiescent current is 60 nA. That is the current the regulator draws from the input when the output is enabled but unloaded — low enough for a coin-cell-powered sensor that needs to run for years on a single battery.
The TPS7A0233DBVR includes over-current protection, over-temperature shutdown, and under-voltage lockout (UVLO). These protect the regulator and downstream circuitry from short circuits, thermal runaway, and input brownout conditions.
Yes, the TPS7A0233DBVR has an enable pin for turning the output on and off. It is active-high — tie it to the input voltage to keep the regulator enabled, or leave it floating to keep the output off.
Yes, the 60 nA quiescent current and low dropout voltage of 0.31 V at 200 mA make it well suited for battery-powered designs, including single-cell Li-ion and coin-cell applications. The enable pin allows the system to shut down the regulator completely when not needed, further extending battery life.
The power-supply rejection ratio is 55 dB at 1 kHz. That level of ripple rejection is adequate for cleaning up a switching pre-regulator output for a sensitive analog load, as long as the load current stays within the 200 mA rating.
