The IRU1206 family of devices are ultra low dropout 1A regulators using PNP transistor as the pass element. These products are ideal when a single input supply is only available and the dropout voltage is less than 1V, exceeding the minimum dropout characteristics of NPN/ PNP hybrid regulators. One common application of these regulators is where input is 3.3V and a 2.5V output is needed. Besides the low dropout of less than 0.5V, other features of the family of the parts are: micro-power shut- down capability and output UVLO detection where Flag pin is switched low when output is below 5% of its nominal point.
This datasheet details the electrical specifications, pin descriptions, and typical applications for the IRU1206, IRU1207, IRU1208, and IRU1209 low dropout voltage regulators. These devices are designed for applications requiring stable voltage regulation with minimal input-output voltage difference. They feature low dropout voltage, low ground current, and fast transient response. The datasheet includes electrical specifications, package information, and application circuits for each model.
