Output Current (mA) Region of Stable C OUT ESR vs. Load Current Application Information Output Voltage Selection The APL5312 are supplied with factory-set output voltages from 1.5V to 3.5V. Capacitor Selection and Regulation Stability The APL5312 uses at least a 1 µF capacitor on the input. This capacitor can use Aluminum, Tantalum or Ceramic capacitors. Input capacitor with large value and low ESR provides better PSRR and line-transient response. The output capacitor also can use Aluminum, Tantalum or Ceramic capacitor, and its proper values is at least 1 µF, ESR must be above 25mΩ. Large output capacitor values can reduce noise and improve load-transient response, stability, and PSRR. With X5R and Y5V dielectrics, 1 µF is sufficient at all operating temperatures. The selection of output capacitor’s is important because it with C OUT form a zero to provide the sufficient phase margin (see the Figure C OUT ESR vs. Load Current). Bypass Capacitor Use a 10nF bypass capacitor at BP for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capacitance slightly decreases the output noise. Value above 0.1 µF and below 1nF are not recommended (see the Figure Output Noise vs. BP Capacitance). Noise, PSRR, and Load-Transient Response The APL5312 is designed to deliver ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery–powered systems. When operating from sources other than batteries, improve PSRR and transient response can be achieved by increasing input and output capacitors, and bypass capacitor to from the passive filtering Instable Stable Instable VOUT=2.5V CIN=COUT=1uF,Y5V |
