Forcing the enable pin TJ − TA θJA low disables the regulator, so current consumed by the regulator goes nearly to zero. Forcing the enable pin high where TJ-TA is the temperature difference between the junction and ambient air. θJA is the thermal resistance enables the output voltage. The enable pin can not float. between junction and ambient air. For continual operation, do not exceed the absolute maxi- Input Capacitor o The APL5156 has high input voltage up to 25V. The input mum junction temperature rating of TJ=125 C. For example: capacitor must be rated to sustain voltages that may be used on the input. An input capacitor may be required In SOT-23-5 package θJA=235 C/W. When operates the o APL5156 at TA=50 C, the maximum power dissipation when the device is not near the source power supply or when supplied by a battery. Small and surface-mounted can be determined as below: o o o o PD(MAX)=(125 C-50 C)/(235 C/W) PD(MAX)=319.1mW ceramic capacitors can be used for bypassing. A larger value may be required if the source supply has high ripple. Output Capacitor Thermal Pad Consideration The APL5156 requires an output capacitor for stability. The design requires 2.2µF or greater on the output to The SOP-8P is a cost-effective package which features a small size, like a standard SOP-8, and a bottom thermal maintain stability. It is optimized by using low-ESR ceramic chip capacitors. The maximum allowable ESR is pad to minimize the thermal resistance of the package is applicable to high current applications. The thermal pad must be soldered down to the copper plane on circuit 3Ω. More capacitance improves transient response. Place the output capacitor as close to the VOUT pin as possible. board. Heat can be conducted away from the thermal pad through the copper plane to ambient. If the copper X7R/X5R dielectric-type ceramic capacitors are recommended because of their temperature performance. X7R plane is not on the top surface of the circuit board, 4 or 6 vias should be used to thermally couple the thermal pad type capacitors change capacitance by 15% over their operating temperature ranges. To use a ceramic chip to the bottom plane. For good thermal conduction, the vias must be plated capacitor with Y5V dielectric, the value must be much higher than an X7R ceramic capacitor to ensure the same through and solder filled. The copper plane used to conduct heat away from the thermal pad should be as large minimum capacitance over the equivalent operating temperature range. as practical.

This is especially important in CMOS RAM keep-alive applications. 0.150 Thermal Consideration The thermal resistance of junction to ambient controls the APL5156's maximum power dissipation.
