Typical dropout voltage is only 290mV at 300mA loading. Designed for use in RF applications, the high PSRR 74dB and low noise 36VRMS 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.

Capacitor Selection and Regulation Stability Input-Output (Dropout) Voltage The APL5312 uses at least a 1F 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 1F, ESR must be above 25m. Large output capacitor values can reduce noise and improve load-transient response, stability, and PSRR. W ith X5R and Y5V dielectrics, 1F is sufficient at all operating temperatures. The selection of output capacitor' is important because s it with COUT form a zero to provide the sufficient phase margin (see the Figure COUT 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 0.1F 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 form the passive filtering techniques (see Output Noise vs. BP Capacitance). Shutdown The APL5312 has an active high enable function. Force SHDN high (>1.6V) enables the VOUT, SHDN low (<0.4V) disables the VOUT. Enter the shutdown mode, it also causes the output voltage to discharge through a 500 resistance to ground. In shutdown mode, the quiescent curCopyright (c) ANPEC Electronics Corp. Rev. A.4 - Jun., 2009 8 rent can reduce to 0.1A. The SHDN pin cannot be floating, a floating SHDN pin may cause an indeterminate state on the output. If it is no use, connect to VIN for normal operation. The minimum input-output voltage differential (dropout) determines the lowest usable supply voltage. The dropout voltage is a function of drain-to-source on resistance multiplied by the load current. Current Limit APL5312 includes a current-limit circuitry for linear regulator. The current-limit protection, which senses the current flowing to the P-channel MOSFET, and controls the output voltage. The point where limiting occurs is IOUT =500mA. The output can be shortened to the ground for an indefinite amount of time without damaging to the part. Thermal Protection Thermal protection limits total power dissipation in the APL5312. When the junction temperature exceeds +160C, the thermal sensor generates a logic signal to turn off the pass element and let IC to cool. When the IC' s junction temperature cools down by 20C, the thermal sensor will turn the pass element on again, resulting in a pulsed output during continuous thermal protection. Thermal protection is designed to protect the IC in the event of fault conditions. Operating Region and Power Dissipation The thermal resistance of the case and circuit board, ambient and junction air temperature, and the rate of air flow all control the APL5312' maximum power s dissipation. The power dissipation across the device is P = IOUT (VIN-VOUT). The maximum power dissipation is: PMAX = (TJ - TA) / (JC + CA ) JA = JC + CA where TJ - TA is the temperature difference between the junction and ambient air. JC is the thermal resistance of the package, CA is the thermal resistance through the printed circuit board, copper traces, and other materials to the surrounding air, JA www.anpec.com.tw APL5312 Application Information (Cont.) Operating Region and Power Dissipation (Cont.) is the thermal resistance between Junction and ambient air. For continual operation, do not exceed the absolute maximum junction Temperature rating of TJ = 125C. For example: The SOT-23-5 package has maximum power dissipation 300mW at TA= 55C, relatively 225mW at SC-70-5 package (see Maximum Power Dissipation vs. Ambient Temperature). VIN = 5V, IOUT = 250mA, VOUT = 3.3V, PD = (5-3.3)V x 150mA = 255mW According the power dissipation issue, we should adapt the SOT-23-5 package. It could reduce the thermal resistance to maintain the IC longer life. The GND pin provides an electrical connection to the ground and channeling heat away. The printed circuit board (PCB) forms a heat sink and dissipates most of the heat into ambient air.
