Bypass Capacitor Thermal Protection Use a 10nF bypass capacitor at BP for low-output voltage Thermal protection limits total power dissipation in the APL5312. When the junction temperature exceeds noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capacitance slightly +160°C, the thermal sensor generates a logic signal to turn off the pass element and let IC to cool. When the IC’s decreases the output noise. Value above 0.1µF and below 1nF are not recommended (see the Figure Output Noise vs. BP Capacitance). junction temperature cools down by 20°C, the thermal sensor will turn the pass element on again, resulting in a Noise, PSRR, and Load-Transient Response pulsed output during continuous thermal protection.

When operating Operating Region and Power Dissipation The thermal resistance of the case and circuit board, from sources other than batteries, improve PSRR and transient response can be achieved by increasing input ambient and junction air temperature, and the rate of air flow all control the APL5312’s maximum power and output capacitors, and bypass capacitor to form the passive filtering techniques (see Output Noise vs. BP dissipation.

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 = 125°C. For example: The SOT-23-5 package has maximum power dissipation 300mW at TA= 55°C, 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.
