This LDO family is designed specifically for batterypowered applications where ultralow quiescent current is a critical parameter. The TPS783, with ultralow IQ (500 nA), is ideal for microprocessors, microcontrollers, and other battery-powered applications. The absence of pulldown circuitry at the output of the LDO provides the flexibility to use the regulator output capacitor as a temporary backup power supply (for example, during battery replacement). The ultralow power and miniaturized packaging allow designers to customiz...
