Product details
Overview
ISL9016AIRUJCZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA LDO outputs with fixed 2.8V and 1.8V voltages, 80dB PSRR at 1kHz, 25µVRMS output noise, and ultra-low quiescent current (49µA single-channel active). It serves as a power management solution for noise-sensitive analog and digital rails in portable battery-powered devices.
For engineers reviewing the ISL9016AIRUJCZ-T datasheet, ISL9016AIRUJCZ-T pinout, ISL9016AIRUJCZ-T application, or ISL9016AIRUJCZ-T equivalent, key selection criteria include dual-rail voltage pairing, reverse current protection, soft-start behavior, thermal shutdown thresholds, and compatibility with 1µF–4.7µF ceramic output capacitors.
Technical Context
The ISL9016AIRUJCZ-T integrates two independent LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 control inputs and VOUT1/VOUT2 outputs. Each channel includes dedicated bandgap reference, error amplifier, pass transistor, and protection circuitry-including reverse current blocking, thermal foldback, and current limiting.
Its architecture enables fast load transient response (<100µs recovery) and stable operation across 1.8V–6.5V input range with ±0.8% output accuracy over temperature. The device implements soft-start via controlled ramp rate (30–60µs/V) and enters <1µA shutdown when both enable pins are low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 2.8V (VOUT1) / 1.8V (VOUT2) - fixed, non-adjustable, factory-set per ordering code |
| Max Output Current | 150mA per channel - supports simultaneous full-load operation on both rails |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from upstream DC/DC converters |
| Output Noise | 25µVRMS (10Hz–100kHz) - suitable for powering RF receivers, ADCs, and precision analog circuits |
| Quiescent Current | 49µA (one LDO active), 80µA (both active) - extends battery life in always-on subsystems |
| Dropout Voltage | 120mV @ 150mA (for VOUT ≥ 2.8V) - enables high-efficiency regulation near battery end-of-life |
| Enable Thresholds | VIL ≤ 0.4V, VIH ≥ 1.1V - compatible with 1.8V/3.3V GPIO control without level-shifting |
| Thermal Shutdown | Activates at +145°C, re-enables at +110°C - protects against sustained overload without latch-off |
Pinout & Package
ISL9016AIRUJCZ-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 | Power and signal reference ground | Must connect directly to PCB ground plane; ties to e-pad for thermal conduction |
| 3 - EN2 | LDO2 enable control input | Active-high logic; 100kΩ pull-up required; floating prohibited |
| 4 - EN1 | LDO1 enable control input | Active-high logic; independent of EN2; enables soft-start on VOUT1 |
| 5 - VOUT2 | LDO2 regulated output (1.8V) | Stable with 1µF–4.7µF X5R/X7R ceramic capacitor to GND |
| 6 - VOUT1 | LDO1 regulated output (2.8V) | Stable with 1µF–4.7µF X5R/X7R ceramic capacitor to GND; reverse current protected |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enable control | EN1 and EN2 allow staggered power-up, rail sequencing, or selective shutdown without affecting the other LDO |
| Reverse current protection | Blocks >99% of backfeed current (≤8µA typical) when VOUT > VIN - critical for multi-rail systems with shared batteries |
| Soft-start with controlled ramp rate | 30–60µs/V output rise time limits inrush current into downstream capacitance during enable |
| Thermal foldback with channel-level shutdown | Disables only overloaded LDO(s) above 50mA while preserving operation of unaffected rail |
| Low-noise, high-PSRR regulation | 25µVRMS noise + 80dB PSRR at 1kHz enables clean power for sensitive analog/RF blocks |
| Wide-input, low-dropout operation | Operates down to 1.8V input and maintains regulation with only 120mV headroom at full 150mA load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D2818MR-G | Same 2.8V/1.8V fixed dual-output, but 100mA max per channel and no reverse current protection | Lacks reverse current blocking and thermal foldback - unsuitable for multi-battery or hot-swap scenarios | Select if cost sensitivity outweighs protection requirements and load current stays below 100mA |
| Richtek RT9013-2818GJ6 | 2.8V/1.8V dual LDO with 300mA per channel, but higher 65µA typical IQ (single-channel) and no soft-start | Higher output current capability but poorer transient response and no controlled ramp-up | Prefer when driving heavier loads is primary concern and noise/sequencing are secondary |
Compared with XC6216D2818MR-G and RT9013-2818GJ6, the ISL9016AIRUJCZ-T uniquely combines dual-rail reverse current protection, soft-start, and sub-50µA quiescent current - making it optimal for battery-constrained, noise-sensitive, and multi-rail sequenced systems.

FAQ
What are the fixed output voltages of the ISL9016AIRUJCZ-T?
The ISL9016AIRUJCZ-T delivers factory-set output voltages of 2.8V on VOUT1 and 1.8V on VOUT2. These values are not adjustable and are confirmed by the "W1" marking on the device body and the ordering code suffix "-T" indicating tape-and-reel packaging. Both outputs maintain ±0.8% accuracy across -40°C to +85°C ambient temperature.
Does the ISL9016AIRUJCZ-T support reverse current protection, and how is it implemented?
Yes, the ISL9016AIRUJCZ-T provides reverse current protection that limits backfeed from VOUT to VIN to ≤8µA typical when VIN = 0V and VOUT = 5.5V. This is achieved through internal MOSFET control that disables the pass element when VOUT exceeds VIN, preventing battery drain in multi-rail systems where one supply may remain active while another is powered down.
What is the minimum recommended output capacitor for stable operation of the ISL9016AIRUJCZ-T?
The ISL9016AIRUJCZ-T is stable with ceramic output capacitors ranging from 1µF to 4.7µF, with X5R or X7R dielectric and ESR up to 200mΩ. A 1µF capacitor is explicitly recommended in the datasheet for each output (VOUT1 and VOUT2), placed close to the device with direct connection to the GND pin and e-pad for optimal transient response and stability.
How does the thermal protection mechanism operate in the ISL9016AIRUJCZ-T?
The ISL9016AIRUJCZ-T features thermal shutdown that activates at +145°C junction temperature and re-enables at +110°C. Crucially, it operates per-channel: only the LDO sourcing >50mA is disabled under overtemperature conditions, allowing the other rail to remain functional. This preserves partial system operation during localized thermal stress, unlike global shutdown architectures.
Can the ISL9016AIRUJCZ-T be used with input voltages below 2.0V?
Yes - the ISL9016AIRUJCZ-T supports input voltages as low as 1.8V, enabling operation directly from single-cell Li-ion (2.8V–4.2V) or NiMH (1.2V nominal) batteries nearing end-of-discharge. At VIN = 1.8V and VOUT1 = 2.8V, the device cannot regulate; however, with VOUT2 = 1.8V, it maintains regulation with only 120mV dropout at 150mA, ensuring usable runtime down to battery voltages near 1.92V.
