LT3022-Slide7

The LT3022 features input voltage capability down to 0.9V and adjustable output voltage down to 0.2V. Its PNP architecture allows for single-supply, low dropout, low input voltage operation. The LT3022’s low VIN capability, coupled with the device’s low 145mV dropout make it ideal for low-voltage, high current rails in digital ICs such as FPGAs, ASICs, DSPs, microprocessors and microcontrollers. It also has applications in general high-efficiency, low-VIN-to-low-VOUT conversion for example 1.2V to 0.9V. In addition, the device offers low power operation at only 400µA quiescent current with less than 10µA in shutdown, saving run time in handheld applications. The LT3022 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 10µF. The LT3022 is highly accurate, featuring ±3% output voltage accuracy over line, load and temperature, 0.1% typical line regulation and 0.1% typical load regulation. The device’s bulletproof internal protection circuitry includes reverse-battery protection, reverse output protection, reverse output-to-input (current) protection, current limiting, and thermal limiting with hysteresis. The device is offered in 2 thermally enhanced packages, a 16-lead 5mm x 3mm DFN package, and a 16-lead MSOP package.
