APL5312
Ultra-Low-Noise, High PSRR, Low-Dropout, 300mA Linear Regulator
Features
General Description
• Wide Operating Voltage: 2.3V~6V
The APL5312 is an ultra low noise, low dropout linear
• Low Dropout Voltage: 290mV @ 3V/300mA
regulator, which operates from 2.3V to 6V input voltage
• Fixed Output Voltages: 1.5V~3.5V with Step 100mV, ^{and delivers up to 300mA. Typical dropout voltage is only}
2.85V
290mV at 300mA loading. Designed for use in RF
• Guaranteed 300mA Output Current
• High PSRR: 74dB before 10kHz
• Low Output Noise: 36µV_RMS at 100Hz to 100kHz
applications, the high PSRR 74dB and low noise 36µV_RMS
makes it an ideal choice.
Design with an internal P-channel MOSET pass element,
the APL5312 maintains a low supply current, indepen-

tures include thermal-shutdown protection and current-
• Over-Temperature Protection
limit protection to ensure specified output current and
• Stable with 1µF Capacitor for Any Load
• Excellent Load/Line Transient
controlled short-circuit current. The APL5312 regulator
comes in a miniature SOT-23-5 and SC-70-5 package.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. 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.
