Typical dropout voltage is only 290mV at 300mA loading. Designed for use in RF applications, the high PSRR 74dB and low noise 36µVRMS makes it an ideal choice. Design with an internal P-channel MOSET pass element, the APL5312 maintains a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown protection and currentlimit protection to ensure specified output current and controlled short-circuit current. The APL5312 regulator comes in a miniature SOT-23-5 and SC-70-5 package.

ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by weight). 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.
