3 DESCRIPTION

The TPS783 family of low-dropout regulators (LDOs) offers the benefits of ultra-low power (IQ = 500nA), and miniaturized packaging.

This LDO is designed specifically for battery-powered applications where ultra-low quiescent current is a critical parameter. The TPS783, with ultra-low IQ (500nA), is ideal for microprocessors, microcontrollers, and other battery-powered applications.

The absence of pulldown circuitry at the output of the TPS783 LDO gives an application the flexibility to use the regulator output capacitor as a temporary backup power supply for a short period of time without the presence of the battery when the LDO is disabled (during battery replacement).

The ultra-low power and miniaturized packaging allow designers to customize power consumption for specific applications. Consult with your local factory representative for exact voltage options and ordering information; minimum order quantities may apply. The TPS783 family is designed to be compatible with the TI MSP430 and other similar products. The enable pin (EN) is compatible with standard CMOS logic. This LDO is stable with any output capacitor greater than 1.0mF. Therefore, this device requires minimal board space because of miniaturized packaging and a potentially small output capacitor. The TPS783 series also features thermal shutdown and current limit to protect the device during fault conditions. All packages have an operating temperature range of TJ = –40°C to +105°C.
