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 VINand 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 VBIASrail that is used to power the internal circuitry of the LDO. Both VINand VBIASconsume very low quiescent current of 1.6 µA and 6 µA, respectively. The low IQand ultra-low dropout features helps in increasing the efficiency of the solution in the power-sensitive applications. For example, VINcan be an output of a high-efficiency, DC/DC step-down regulator, and the VBIASpin 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.
