Product details
Overview
ISL9016AIRUNCZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs with fixed 3.3V and 1.8V voltages, ultra-low noise (25µVRMS), high PSRR (80dB at 1kHz), and shutdown current <1µA - designed for power sequencing in portable medical handhelds and battery-powered audio subsystems.
For engineers reviewing the ISL9016AIRUNCZ-T datasheet, ISL9016AIRUNCZ-T pinout, ISL9016AIRUNCZ-T application, or ISL9016AIRUNCZ-T equivalent, key selection criteria include per-channel enable control, reverse current protection, soft-start ramp rate (30–60 µs/V), ±0.8% output accuracy over -40°C to +85°C, and stability with 1µF–4.7µF ceramic capacitors.
Technical Context
The ISL9016AIRUNCZ-T integrates two independent LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 control inputs and VOUT1/VOUT2 outputs. Each LDO employs bandgap-referenced error amplifiers with internal current limiting (typ. 265mA), thermal shutdown (145°C trip), and reverse current protection that limits IORLC to <15µA when VIN = 0V and VOUT = 5.5V.
Its architecture supports fast load transient response via optimized internal compensation and soft-start circuitry that controls output ramp rate (30–60 µs/V) to limit input surge. The device operates across 1.8V–6.5V input while maintaining dropout as low as 120mV at 150mA for VOUT ≥ 2.8V, and remains stable with 1µF–4.7µF X5R/X7R ceramic output capacitors (ESR ≤ 200mΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 3.3V (VOUT1) and 1.8V (VOUT2), factory-set, no external feedback required |
| Max Output Current | 150mA per channel - supports simultaneous powering of RF and baseband ICs |
| PSRR | 80dB at 1kHz - suppresses switching noise from upstream DC-DC converters |
| Output Noise | 25µVRMS (10Hz–100kHz) - suitable for noise-sensitive analog/RF circuits |

| Accuracy | ±0.8% at +25°C, ±1.8% over -40°C to +85°C - ensures reliable logic-level compliance |
Pinout & Package
ISL9016AIRUNCZ-T is housed in a 1.6mm × 1.6mm, 6-lead Ultra Thin Dual Flat No-Lead (UTDFN) package with exposed thermal pad (L6.1.6x1.6A). The e-pad must be soldered to PCB ground for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | LDO input supply rail | Accepts 1.8V–6.5V; requires 1µF ceramic decoupling capacitor to GND |
| 2 - GND | Common reference and return path | Must connect directly to PCB ground plane; ties e-pad and all internal grounds |
| 3 - EN2 | LDO2 enable control input | Active-high logic (VIH ≥ 1.1V); 100kΩ pull-up required; disables VOUT2 independently |
| 4 - EN1 | LDO1 enable control input | Active-high logic (VIH ≥ 1.1V); 100kΩ pull-up required; disables VOUT1 independently |
| 5 - VOUT2 | 1.8V regulated output | Delivers up to 150mA; stable with 1µF–4.7µF ceramic cap (X5R/X7R) to GND |
| 6 - VOUT1 | 3.3V regulated output | Delivers up to 150mA; same capacitor requirements as VOUT2; reverse current protected |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-LDO enable | EN1/EN2 allow staggered power-up/down sequencing for SoC core/I/O rails |
| Reverse current protection | Blocks >99.9% backfeed from VOUT to VIN when input is grounded or floating - prevents battery drain |
| Soft-start ramp control | 30–60 µs/V slope limits inrush current during enable - avoids input rail collapse |
| Thermal foldback protection | Shuts down only overloaded LDO (≥50mA) at 145°C; other LDO continues operating |
| Low-noise, high-PSRR regulation | 25µVRMS noise + 80dB PSRR at 1kHz enables clean power for ADCs, PLLs, and RF receivers |
| Wide input voltage range | 1.8V–6.5V input supports single-cell Li-ion, USB, and multi-rail systems without pre-regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D331MR-G | Single-output 3.3V LDO (150mA); no dual-rail or 1.8V option; PSRR = 70dB @ 1kHz | Requires two devices to match ISL9016AIRUNCZ-T's dual-voltage capability; larger board area | Select only if needing standalone 3.3V regulation with identical footprint constraints and lower cost sensitivity. |
| Ricoh RP512K331D-TR-F | Dual 3.3V outputs (no mixed-voltage option); higher IQ (120µA both on); PSRR = 75dB @ 1kHz | Cannot supply asymmetric rails (3.3V + 1.8V); unsuitable for mixed-voltage SoC interfaces | Consider only for systems requiring dual 3.3V rails with tighter thermal margin (θJA = 95°C/W vs. 117.5°C/W). |
Compared with XC6216D331MR-G and RP512K331D-TR-F, the ISL9016AIRUNCZ-T uniquely delivers factory-matched 3.3V/1.8V outputs in one UTDFN package with superior PSRR, lower noise, and true per-rail enable - enabling smaller footprint, lower system IQ, and higher signal-chain SNR in space-constrained portable designs.

FAQ
What are the fixed output voltages of the ISL9016AIRUNCZ-T?
The ISL9016AIRUNCZ-T is factory-configured with VOUT1 = 3.3V and VOUT2 = 1.8V. These values are laser-trimmed during production and cannot be adjusted externally. Both outputs deliver up to 150mA each and maintain ±0.8% accuracy at +25°C, degrading to ±1.8% across the full -40°C to +85°C operating range. This fixed dual-rail configuration eliminates external resistor networks and simplifies design for applications requiring precise, matched voltage pairs.
Does the ISL9016AIRUNCZ-T require external capacitors, and what values are recommended?
Yes, the ISL9016AIRUNCZ-T requires external ceramic capacitors: a 1µF input capacitor (X5R/X7R) between VIN and GND, and individual 1µF–4.7µF output capacitors (X5R/X7R) from each VOUT pin to GND. The datasheet specifies stability with ESR up to 200mΩ and recommends placing capacitors close to the pins with low-inductance ground connections. Using 1µF is optimal for most applications; 4.7µF improves transient response under heavy dynamic loads.
How does reverse current protection work in the ISL9016AIRUNCZ-T?
The ISL9016AIRUNCZ-T actively blocks reverse current flow from VOUT to VIN when VIN is disconnected, grounded, or held at a lower voltage than the output. When VIN = 0V and VOUT = 5.5V, reverse leakage is typically <8µA - preventing battery drain or unintended power coupling in multi-rail systems. This protection is automatic and requires no external components, making it ideal for USB-powered devices that may experience hot-plug scenarios or shared-battery architectures.
What is the thermal shutdown behavior of the ISL9016AIRUNCZ-T?
The ISL9016AIRUNCZ-T triggers thermal shutdown at +145°C (TSD+) and re-enables at +110°C (TSD−). Crucially, it implements per-LDO thermal foldback: only the LDO sourcing >50mA shuts down during overtemperature events, allowing the other rail to remain operational. This fault-isolation behavior preserves system functionality - for example, keeping an MCU powered while disabling a high-current sensor interface - and avoids full-system resets in portable instrumentation.
Can the ISL9016AIRUNCZ-T operate from a single-cell Li-ion battery?
Yes, the ISL9016AIRUNCZ-T supports input voltages from 1.8V to 6.5V, making it compatible with discharged single-cell Li-ion batteries (down to ~3.0V nominal, ~2.8V cutoff). With its 120mV dropout at 150mA for the 3.3V output, the device can sustain regulation until VIN drops to ~3.42V - covering >95% of the usable battery range. Its 49µA quiescent current in single-LDO mode further extends runtime in low-power sleep states.
