1 / 16 page Low I Q, Low Dropout 150mA Fixed Voltage Regulator Copyright © ANPEC Electronics Corp. Rev. B.4 - May., 2005 APL5151/2/3/4 www.anpec.com.tw 1 ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders. Features General Description The APL5151/2/3/4 is micropower, low noise, low drop- out linear regulator. Operate from 3V to 6V input volt- age and deliver up to 150mA. Typical output noise is just 60uV RMS with the addition of an external 0.33uF bypass capacitor in BP pin and typical dropout voltage is only 220mV at 150mA loading. Designed for use in battery-powered system, the low 50uA quiescent cur- rent makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5151/2/ 3/4 maintains a low supply current, independent of the load current and dropout voltage. Other features include reverse current protection, thermal-shutdown protection, current limit protection to ensure speci- fied output current and controlled short-circuit current. TheAPL5151/2/3/4 regulators come ina miniatureSOT- 23-5 package.
