The TPS78318DDCT is a Low-dropout Regulator (LDO) offers the benefits of ultralow power. This LDO is designed specifically for battery-powered applications where ultralow quiescent current is a critical parameter. The TPS78318DDCT with ultralow IQ (500nA), 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 TPS78318DDCT compatible with the TI MSP430 and other similar products. The enable pin (EN) is compatible with standard CMOS logic. This device allows for minimal board space because of miniaturized packaging and a potentially small output capacitor. The TPS78318DDCT also features thermal shutdown and current limit to protect the device during fault conditions.
