[2] The Type 2 buck regulator is capable of providing output current above the nominal max current specification as long as it does not reach the current limitation. However, if operating above the nominal maximum current, overall thermal considerations must be taken to prevent reaching PMIC thermal shutdown during high ambient temperature conditions. [3] Max RDS(on) does not include bond wire resistance. Consider ± 50 % tolerance to account for bond wire and pin loss. Table 58. Recommended external components Symbol Parameter Min Typ Max Unit L Output inductor Maximum inductor DC resistance 50 mΩ [1] Minimum saturation current at full load: 3.0 A 0.47 1.0 1.5 µH Cout Output capacitor Use 2 x 22 μF, 6.3 V X7T ceramic capacitor to reduce output capacitance ESR. — 44 — µF Cin Input capacitor 4.7 μF, 10 V X7R ceramic capacitor — 4.7 — µF [1] Keep inductor DCR as low as possible to improve regulator efficiency. 15.5 Linear regulators The PF7100 has two low drop-out (LDO) regulators with the following features: • 400 mA current capability • Input voltage range from 2.5 V to 5.5 V • Programmable output voltage between 0.8 V and 5.0 V • Soft-start ramp control during power up (enable) • Discharge mechanism during power down (disable) • OTP programmable load switch mode |
