The TPS7A10 is an ultra-small, low quiescent current, low-dropout regulator (LDO) that can source 300 mA with an outstanding ac performance (load and line transient responses). This device has an input range of 0.75 V to 3.3 V, and output range of 0.5 V to 3.0 V with a very high accuracy of 1.5% over load, line and temperature. This performance is ideal for powering the lower core voltages of the modern MCUs and analog sensors.

The main power path is through V_IN and can be connected to a power supply as low as 70 mV above the output voltage. This device supports very low input voltages with the use of an additional V_BIAS rail that is used to power the internal circuitry of the LDO. Both V_IN and V_BIAS consume very low quiescent current of 1.6 µA and 6 µA, respectively. The low I_Q and ultra-low dropout features helps in increasing the efficiency of the solution in the power-sensitive applications. For example, V_IN can be an output of a high-efficiency, DC/DC step-down regulator, and the V_BIAS pin can be connected to a rechargeable battery.

The TPS7A10 is equipped with an active pull-down circuit to quickly discharge the output when disabled, and provides a known start-up state.

The TPS7A10 is available in an ultra-small, 5-pin DSBGA (YKA) package that makes the device suitable for space-constrained applications. The device is also available in a 6-pin WSON (DSE) package.
