High Performance 2A and 3A Linear Regulators ISL80102, ISL80103 Features The ISL80102 and ISL80103 are low voltage, high-current, single Stable with all capacitor types (Note 10) output LDOs specified for 2A and 3A output current, respectively. 2A and 3A output current ratings These LDOs operate from the input voltages of 2.2V to 6V and 2.2V to 6V input voltage range are capable of providing the output voltages of 0.8V to 5V on the adjustable V versions. Fixed output voltage options are OUT 1.8% V accuracy guaranteed over line, load and OUT available in 1.8V, 2.5V, 3.3V and 5V. Other custom voltage T = -40C to +125C J options available upon request. Very low 120mV dropout voltage at 3A (ISL80103) For applications that demand in-rush current less than the Fixed and adjustable V versions current limit, an external capacitor on the soft-start pin provides OUT adjustment. The ENABLE feature allows the part to be placed into Very fast transient response a low quiescent current shutdown mode. A sub-micron BiCMOS Excellent 62dB PSRR process is utilized for this product family to deliver the best in class analog performance and overall value. 100V output noise RMS These CMOS (LDOs) will consume significantly lower quiescent Power-good output current as a function of load over bipolar LDOs, which translates Adjustable in-rush current limiting into higher efficiency and the ability to consider packages with smaller footprints. The quiescent current has been modestly Short circuit and over-temperature protection compromised to enable a leading class fast load transient Available in a 10 Ld DFN response, and hence a lower total AC regulation band for an LDO Servers in this category.
