Product details
Overview
ISL9016IRUGGZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs at fixed 2.7V each, featuring 80dB PSRR at 1kHz, 25µVRMS output noise, and 120mV dropout at 150mA for high-efficiency power conditioning in space-constrained portable electronics.
For engineers reviewing the ISL9016IRUGGZ-T datasheet, ISL9016IRUGGZ-T pinout, ISL9016IRUGGZ-T application, or ISL9016IRUGGZ-T equivalent, this device supports independent enable control per channel, reverse current protection, soft-start, and stable operation with 1µF–4.7µF ceramic capacitors-critical for battery-powered load transient integrity and low-noise analog supply design.
Technical Context
The ISL9016IRUGGZ-T integrates two fully independent LDO regulators sharing only VIN and GND, each with dedicated EN1/EN2 control, internal bandgap reference, and thermal shutdown circuitry that disables individual LDOs above +145°C while preserving the other if its load remains below 50mA. Its architecture enables fast load transient response via adaptive biasing and soft-start ramp control (30–60 µs/V).
It operates across 1.8V–6.5V input range with UVLO thresholds at 1.71V (rising) and 1.55V (falling), supports reverse current protection (≤8µA when VIN=0V, VOUT=5.5V), and maintains ±0.8% output voltage accuracy at +25°C and ±1.8% over –40°C to +85°C-enabling reliable dual-rail regulation in mixed-signal SoC subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7V per channel (VOUT1 = VOUT2 = 2.7V); eliminates external feedback resistors and ensures precise rail matching for dual-core or I/O + core supply schemes. |
| Max Output Current | 150mA per LDO; sufficient for powering RF transceivers, sensor interfaces, or low-power microcontrollers without thermal derating in µTDFN package. |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz; suppresses switching noise from upstream DC-DC converters, critical for ADC reference or PLL supply rails. |
| Output Noise | 25µVRMS (10Hz–100kHz); enables clean biasing of precision op-amps and RF front-end components without additional filtering. |
| Dropout Voltage | 120mV @ 150mA (for VO ≥ 2.8V); allows operation down to 2.82V input for 2.7V outputs, maximizing battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 49µA (one LDO active), 80µA (both active); extends standby time in always-on sensor nodes or real-time clock domains. |
| Shutdown Current | <1.0µA (typical); meets ultra-low-power requirements for emergency wake-up circuits or energy-harvesting applications. |
Pinout & Package
ISL9016IRUGGZ-T uses a 1.6mm × 1.6mm, 6-lead µTDFN package with exposed thermal pad (E-Pad) connected to GND. The compact footprint supports high-density PCB layouts in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO Input Supply | Accepts 1.8V–6.5V input; requires 1µF ceramic capacitor to GND for stability and EMI suppression. |
| GND (Pin 2) | System Ground Reference | Common return path for both LDOs and E-Pad; must connect directly to PCB ground plane for thermal and noise performance. |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic input; 100kΩ pull-up required to avoid floating; enables independent sequencing of second output rail. |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic input; decouples startup timing from LDO2, supporting staggered power-up in multi-voltage SoCs. |
| VOUT2 (Pin 5) | LDO2 Regulated Output | Delivers fixed 2.7V/150mA; connects to 1µF–4.7µF ceramic capacitor (X5R/X7R) with ESR ≤200mΩ for stability. |
| VOUT1 (Pin 6) | LDO1 Regulated Output | Delivers fixed 2.7V/150mA; identical electrical specs to VOUT2, enabling symmetrical dual-rail designs. |
Key Features
| Feature | Design Value |
|---|---|
| Independent Dual Enable Control | EN1 and EN2 allow separate power sequencing, dynamic rail disabling, and partial-system sleep modes without affecting the other LDO. |
| Reverse Current Protection | Prevents backflow from VOUT to VIN when input is grounded or open; limits reverse leakage to ≤8µA at 5.5V output-essential for hot-swap and backup-battery scenarios. |
| Soft-Start Ramp Rate | 30–60 µs/V controlled slew rate prevents input current surges during enable, reducing stress on source capacitors and upstream regulators. |
| Thermal Shutdown with Selective Disable | Shuts down only the overloaded LDO (>50mA) above +145°C, preserving functionality of the second rail-improves system resilience in thermally constrained enclosures. |
| Stable with Low-ESR Ceramic Capacitors | Guaranteed stability with 1µF–4.7µF X5R/X7R ceramics (ESR ≤200mΩ), eliminating need for costly tantalum or aluminum electrolytics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D272MR-G | Single-output 2.7V LDO (150mA), no dual-channel capability; lacks EN2, reverse current protection, and PSRR >70dB beyond 100kHz. | Requires two separate ICs to replicate ISL9016IRUGGZ-T's dual-rail function, increasing board area and BOM count. | Select only when dual-rail independence is unnecessary and PCB space permits discrete implementation. |
| Ricoh RP111N271B-TR-F | Dual 2.7V LDO (200mA/channel), but higher 65µVRMS noise and no soft-start; PSRR peaks at 70dB @ 1kHz then drops sharply above 10kHz. | Suitable for less noise-sensitive digital rails but inadequate for RF/analog subsystems requiring broadband PSRR and low RMS noise. | Choose only for cost-driven digital-only applications where 25µVRMS noise and 45dB @ 1MHz PSRR are non-critical. |
Compared with XC6216D272MR-G and RP111N271B-TR-F, the ISL9016IRUGGZ-T uniquely delivers matched dual 2.7V rails with industry-leading 25µVRMS noise, 45dB PSRR at 1MHz, and integrated soft-start-making it the sole option for compact, low-noise, sequenced dual-rail designs in portable medical and communications equipment.

FAQ
What output voltage does the ISL9016IRUGGZ-T provide?
The ISL9016IRUGGZ-T provides two fixed 2.7V regulated outputs (VOUT1 and VOUT2), as indicated by the "GG" suffix in the part number per Intersil's ordering table. Each output delivers up to 150mA with ±0.8% accuracy at +25°C and ±1.8% over –40°C to +85°C, eliminating external resistor networks and ensuring matched rail performance for dual-core or I/O+core architectures.
Does the ISL9016IRUGGZ-T require external capacitors, and what values are recommended?
Yes, the ISL9016IRUGGZ-T requires ceramic output capacitors of 1µF to 4.7µF (X5R or X7R dielectric, ESR ≤200mΩ) on each VOUT pin, plus a 1µF ceramic input capacitor on VIN. These values ensure stability, low-noise operation, and optimal transient response. Placement must be close to the pins with direct GND connections-per the datasheet's layout guidelines-to maintain PSRR and prevent oscillation.
How does the enable functionality work on the ISL9016IRUGGZ-T?
The ISL9016IRUGGZ-T features two independent active-high enable pins: EN1 controls VOUT1 and EN2 controls VOUT2. Each requires a 100kΩ pull-up resistor to a valid logic rail; floating pins are prohibited. When ENx is high, its corresponding LDO powers up with soft-start (400–600µs to 95% of 2.7V); when low, the LDO shuts down, drawing <1µA. This enables flexible power sequencing and partial-system sleep modes not possible with single-enable dual-LDOs.
What protections are built into the ISL9016IRUGGZ-T?
The ISL9016IRUGGZ-T integrates current limit (265mA typical), thermal shutdown (+145°C trip, +110°C recovery), reverse current protection (≤8µA reverse leakage when VIN=0V, VOUT=5.5V), and undervoltage lockout (1.71V rising threshold). Critically, thermal protection disables only the overloaded LDO (>50mA), preserving the second rail-a feature absent in most dual-LDO competitors and vital for fault-tolerant portable systems.
Is the ISL9016IRUGGZ-T compatible with lead-free PCB assembly processes?
Yes, the ISL9016IRUGGZ-T is Pb-free and RoHS compliant, using a tin-bismuth e6 termination finish qualified for standard Pb-free reflow profiles (peak temperature ≥260°C). Its 6-lead µTDFN package (L6.1.6x1.6A) meets JEDEC MO-229 standards and has an MSL rating documented in Intersil's device information page-ensuring compatibility with automated SMT lines and long-term reliability in consumer and industrial assemblies.
