LDO offers active output discharge

The IC delivers up to 200mA of continuous output current with a 300mV dropout voltage at full load. It includes an internal NMOS pull down that discharges the output voltage if either the SHDN pin is driven low or the input voltage is turned off. This rapid output discharge helps protect the load in applications requiring power conditioning on both start up and shutdown, such as high end imaging sensors. The LT3063 features a 1.6 to 45V input voltage range and delivers adjustable output voltages from 0.6 to 19V. A single capacitor provides programmable ultra low noise operation and reference soft-start functionality, preventing output voltage overshoot at turn-on. The IC's output voltage tolerance is ±2% over line, load and temperature. Its input and output voltage range, fast transient response, low quiescent current of 45µA (operating) and <3µA (in shutdown) make it suitable for portable battery powered systems that require optimum run time, and for usage in automotive, industrial and avionic power supply applications.
