... PNP pass transistor, including prolonged battery life. The P-channel MOSFET does not require a base driver, thus quiescent current is dramatically reduced. The AS1358/AS1359 LDOs do not exhibit prob- lems associated with typical PNP-based LDOs, and consume only 40µA of quiescent current in light load and 220µA in ...
