The family operates with very low input voltage (1.4V) and low dropout voltage (typically 300mV at full load), making it an efficient stand-alone power supply or post regulator for battery or switch mode power supplies. The 3A output current make the PAM3130 family suitable for powering many microprocessors and FPGA supplies. The PAM3130 family also has low output noise (typically 40μVRMS with 2.2μF output capacitor), making it ideal for use in telecom equipment. External Capacitor Requirements A 2.2μF or larger ceramic input bypass capacitor, connected between V IN and GND and located close to the PAM3130, is required for stability. A 1.0uF minimum value capacitor from V O to GND is also required. To improve transient response, noise rejection, and ripple rejection, an additional 10μF or larger, low ESR capacitor is recommended at the output. A higher value, low ESR output capacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inches from the power source, especially if the minimum input voltage of 1.4 V is used. Regulator Protection The PAM3130 features internal current limiting, thermal protection and short circuit protection. During normal operation, the PAM3130 limits output current to about 4.5A. When current limiting engages, the output voltage scales back linearly until the over current condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds 150°C, thermalprotection circuitry will shut down. Once the device has cooled down to approximately 50°C below the high temp trip point, regulator operation resumes. The short circuit current of the PAM3130 is about 1A when its output pin is shorted to ground. Thermal Information The amount of heat that an LDO linear regulator generates is: P D=(V IN-V O)I O. All integrated circuits have a maximum allowable junction temperature (T J max) above which normal operation is not assured. A system designer must design the operating environment so that the operating junction temperature (T J) does not exceed the maximum junction temperature (T J max). The two main environmental variables that a designer can use to improve thermal performance are air flow and external heatsinks. The purpose of this information is to aid the designer in determining the proper operating environment for a linear regulator that is operating at a specific power level. In general, the maximum expected power (P D(max)) consumed by a linear regulator is computed as: PDmax= (VI (avg)-VO (avg))×IO (avg)+VI (avg)×I (Q ) (1) Where: l V I (avg) is the average input voltage. l V O(avg) is the average output voltage. l I O(avg) is the average output current. l I (Q) is the quiescent current. For most LDO regulators, the quiescent current is insignificant compared to the average output current; therefore, the term V I(avg) xI (Q) can be neglected. The operating junction temperature is computed by adding the ambient temperature (T A) and the increase in temperature due to the regulator' s power dissipation. The temperature rise is computed by multiplying the maximum expected power dissipation by the sum of the thermal resistances between the junction and the case ( R θJC), the case to heatsink (R θCS), and t h e h e a t s i n k t o a m b i e n t ( R θSA) . T h e r m a l resistances are measures of how effectively an object dissipates heat. Typically, the larger the device, the more surface area available for power dissipation so that the object 's thermal resistance will be lower.
