Texas Instruments TPS7B91 Low-Dropout (LDO) Linear Voltage Regulators are low-quiescent current devices. The TPS7B91 offers a wide input voltage range (up to 40V), wide output range, and low-power operation in miniaturized packaging. The wide output range is up to VIN − VDO for the adjustable configuration or up to 12V for the fixed configuration. The TPS7B91 is optimized to power microcontrollers and other low-power loads for battery-powered applications. The TPS7B91 is stable with an output capacitor range of 1.0µF to 47µF.
