This LDO operates from input voltages of 2.2V to 6V. Fixed output voltage options are available in 1.8V, 2.5V, 3.3V and 5.0V versions. Other custom voltage options are available upon request. For the adjustable output version of the ISL80101, please refer to the ISL80101-ADJ datasheet. • ±1.8% VOUT accuracy guaranteed over line, load and TJ = -40°C to +125°C A submicron BiCMOS process is utilized for this product family to deliver the best-in-class analog performance and overall value. This CMOS LDO consumes significantly lower quiescent current as a function of load compared to bipolar LDOs, which translates into higher efficiency and packages with smaller footprints. State-of-the-art internal compensation achieves a very fast load transient response. An external capacitor on the soft-start pin provides an adjustable soft-starting ramp. The ENABLE feature allows the part to be placed into a low quiescent current shutdown mode. A power-good logic output signals a fault condition. • Excellent 65dB PSRR Table 1 shows the differences between the ISL80101 and others in its family: • Post regulation of switched mode power supplies PART NUMBER PROGRAMMABLE ILIMIT ILIMIT (DEFAULT) ADJ or FIXED VOUT ISL80101-ADJ No 1.75A ADJ ISL80101 No 1.75A 1.8V, 2.5V, 3.3V, 5.0V ISL80101A Yes 1.62A ADJ ISL80121-5 Yes 0.75A 5.0V 5.4V ± 10% 10µF CIN 10 VIN VOUT 9 V IN 10k R3 SENSE 5.0V ± 1.8% 2 10µF COUT 3 ISL80101 7 6 0.01µF CSS VOUT 1 ENABLE PG 100k RPG 4 SS • Very fast transient response • Programmable soft-starting • Power-good output • Current limit protection • Thermal shutdown function • Available in a 10 Ld DFN package • Pb-free (RoHS compliant) Applications • DSP, FPGA and µP core power supplies • Noise-sensitive instrumentation systems • Industrial systems • Medical equipment • Telecommunications and networking equipment • Servers • Hard disk drives (HD/HDD) Related Literature • See AN1592, “ISL80101 High Performance 1A LDO Evaluation Board User Guide” 140 DROPOUT VOLTAGE (mV) TABLE 1.

A minimum 10µF X5R/X7R output capacitor is required for stability. See “External Capacitor Requirements” on page 8 for more details. Sense is the LDO's output feedback, providing a remote voltage sensing. This is an open-drain logic output used to indicate the status of the output voltage. Logic low indicates VOUT is not in regulation. This pin must be grounded if not used. Ground External capacitor on this pin adjusts startup ramp and controls in-rush current. VIN independent chip enable. TTL and CMOS compatible. EPAD at ground potential; It is recommended to solder the EPAD to the ground plane. 3 FN6931.2 September 25, 2015 ISL80101 Absolute Maximum Ratings Thermal Information VIN Relative to GND (Note 5) . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3V to +6.5V VOUT Relative to GND (Note 5) . . . . . . . . . . . . . . . . . . . . . . . . -0.3V to +6.5V PG, ENABLE, SENSE, SS Relative to GND (Note 5) . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3V to +6.5V ESD Rating Human Body Model (Tested per JESD22 A114F) . . . . . . . . . . . . . . .2.5kV Machine Model (Tested per JESD22 A115C) . . . . . . . . . . . . . . . . . 250V Charge Device Model (Tested per JESD22-C101C). . . . . . . . . . . . . . . 2kV Latch-Up (Tested per JESD78C, Class 2, Level A) . . . . ±100mA at +125°C Thermal Resistance (Typical) JA (°C/W) JC (°C/W) 10 Ld DFN Package (Notes 6, 7) . . . . . . . . 48 7 Storage Temperature Range. . . . . . . . . . . . . . . . . . . . . . . .-65°C to +150°C Junction Temperature . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .+150°C Pb-Free Reflow Profile . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . see TB493 Recommended Operating Conditions (Notes 8, 9) Junction Temperature Range (TJ) (Note 8) . . . . . . . . . . . .-40°C to +125°C VIN Relative to GND . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2.2V to 6V VOUT Range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 800mV to 5V PG, ENABLE, SENSE, SS relative to GND . . . . . . . . . . . . . . . . . . . . 0V to 6V PG Sink Current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
