The LT3061 low dropout (LDO) linear voltage regulator integrates active output discharge and delivers up to 100 mA of continuous output current with a 250-mV dropout voltage at full load. The device includes an internal NMOS pull-down that discharges the output voltage if either the SHDN pin goes low or the input voltage turns off. This rapid output discharge helps protect the load in apps requiring power conditioning on both start-up and shutdown, like high-end imaging sensors. Other features include a 1.6V to 45V input voltage range, adjustable output voltages from 0.6V to 19V, an output-voltage accuracy of ±2% over line, load, and temperature, and a quiescent current of 45 µA operating and less than 2 µA in shutdown. Available in eight-lead, 2 mm x 3 mm DFN and MSOP packages, pricing starts at $1.55 each/1,000. A datasheet is available at http://cds.linear.com/docs/en/datasheet/3061f.pdf
