1 / 23 page Low I Q, Low Dropout 500mA Fixed Voltage Regulator Copyright © ANPEC Electronics Corp. Rev. B.2 - May., 2005 APL5501/2/3 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 Design with an internal P-channel MOSFET pass transistor, the APL5501/2/3 maintains a low supply current, independent of the load current and dropout voltage. Other features include rev erse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and con- trolled short-circuit current. The APL5501/2/3 regu- lator comes in a miniature SOT-23-5, SOT-89, SOT- 89-5, SOT-223, SO-8, TO-252 and TO-252-5 packages. Applications • Notebook Computer • PDA or Portable Equipments • Noise-Sensitive Instrumentation Systems • Low Noise : 50 µV RMS (100Hz to 100kHz) • Low Quiescent Current : 50 µA (No load) • Low Dropout Voltage : 170mV (@500mA) • Very low Shutdown Current : < 0.5uA • Fixed Output Voltage : 1.3V ~ 3.4V • Stable with 4.7uF Output Capacitor • Stable with Aluminum, Tantalum or Ceramic Capacitors • Reverse Current Protection • No Protection Diodes Needed • Built in Thermal Protection • Built in Current Limit Protection • Controlled Short Circuit Current : 150mA • Fast Transient Response • Short Setting Time • SOT-23-5, SOT-89, SOT-89-5, SOT-223, SO-8, TO-252 and TO-252-5 Packages • Lead Free Available (RoHS Compliant) Pin Configuration SOT-89 (Top View) V IN GND V OUT 1 2 3 TAB is GND SOT-89-5 (Top View) SO-8 (Top View) TO-252-5 (Top View) General Description The APL5501/2/3 is micropower, low noise, low drop- out linear regulator. Operate from 2.7V to 6V input voltage and deliver up to 500mA. Typical output noise is just 50 µV RMS with the addition of an external 0.1µF bypass capacitor in BP pin and typical dropout volt- age is only 170mV at 500mA loading . Designed for use in battery-powered system, the low 50uA quies- cent current makes it an ideal choice.
