These LDOs operate from the input voltages of • Stable with ceramic capacitors (Note11) 2.2V to 6V and are capable of providing the output voltages of • 2A and 3A output current ratings 0.8V to 5.5V. • 2.2V to 6V input voltage range An external capacitor on the soft-start pin provides adjustment • ±1.8% VOUT accuracy assured over line, load, and TJ=-40°C for applications that demand inrush current less than the to +125°C current limit. The ENABLE feature allows the part to be placed • Very low 120mV dropout voltage at 3A (ISL80103) into a low quiescent current shutdown mode. A submicron BiCMOS process is used for this product family to deliver • Very fast transient response best-in-class analog performance and overall value. • Excellent 62dB PSRR These CMOS (LDOs) consume significantly lower quiescent • 49µVRMS output noise current as a function of load over bipolar LDOs, so they are • Power-good output more efficient and allow packages with smaller footprints. The quiescent current has been modestly compromised to enable • Adjustable inrush current limiting a leading class fast load transient response, and hence a lower • Short-circuit and over-temperature protection total AC regulation band for an LDO in this category. • Available in a 10 Ld DFN Related Literature Applications For a full list of related documents, visit our website • Servers •ISL80102, ISL80103 product pages • Telecommunications and networking • Medical equipment • Instrumentation systems • Routers and switchers ISL80102, ISL80103 1.8V 2.5V ±10% 9 1 VIN VIN VOUT VOUT CIN 10 VIN VOUT 2 COUT 10µF 10µF RPG R1 100kΩ 10kΩ 4 PG PGOOD 7 EN ENABLE OPEN DRAIN COMPATIBLE 6 **CPB R3 SS 47pF 2.61kΩ 3 *CSS ADJ GND 5 R4 1.0kΩ *CSS is optional (see Note12 on page5). **CPB is optional (see “Functional Description” on page12 for more information).

NOTES: 5. θJA is measured in free air with the component mounted on a high-effective thermal conductivity test board with “direct attach” features. See TB379. 6. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside. 7. For θJB, the board temperature is taken on the board near the edge of the package, on a copper trace at either lead #3 or lead #5, as applicable. See TB379 8. ABS max voltage rating is defined as the voltage applied for a lifetime average duty cycle above 6V of 1%. Electrical Specifications Unless otherwise noted, all parameters are established over the following specified conditions: 2.2V < VIN < 6V, VOUT = 0.5V, TJ = +25°C, ILOAD = 0A. Applications must follow thermal guidelines of the package to determine worst case junction temperature. Refer to “Functional Description” on page12 and TB379. Boldface limits apply across the operating temperature range, -40°C to +125°C. Pulse load techniques used by ATE to ensure TJ = TA defines established limits.
