Product details
Overview
ISL9016IRUFWZ-T from Intersil is a dual-channel low-dropout linear regulator IC delivering 150mA per channel with output voltages fixed at 2.5V (VOUT1) and 1.2V (VOUT2), operating from 1.8V to 6.5V input. It features 80dB PSRR at 1kHz, 25µVRMS output noise, ±0.8% output accuracy, and reverse current protection-designed for power sequencing in portable medical handhelds and battery-powered smart devices.
For engineers reviewing the ISL9016IRUFWZ-T datasheet, ISL9016IRUFWZ-T pinout, ISL9016IRUFWZ-T application, or ISL9016IRUFWZ-T equivalent, key selection criteria include dual independent enable control, ultra-low quiescent current (49µA single-LDO active), stable operation with 1µF–4.7µF ceramic capacitors, and thermal shutdown at 145°C.
Technical Context
The ISL9016IRUFWZ-T integrates two independent LDO regulators sharing a common VIN and GND, each with dedicated EN1/EN2 control pins enabling selective power domain activation. Its bandgap reference and adaptive biasing circuitry deliver fast load transient response and maintain regulation across –40°C to +85°C ambient temperature.
Each LDO employs internal current limiting (265mA typ), thermal shutdown (145°C trip), and reverse current protection that limits VOUT-to-VIN leakage to <8µA when VIN = 0V and VOUT = 5.5V. Soft-start ramps output voltage at 30–60µs/V to suppress input surge during enable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (VOUT1/VOUT2) | 2.5V / 1.2V - Fixed, factory-trimmed outputs eliminating external resistor networks. |
| Max Output Current per Channel | 150mA - Sustained continuous delivery per LDO without thermal derating under specified conditions. |
| PSRR @ 1kHz / 1MHz | 80dB / 45dB - Enables clean power delivery to noise-sensitive analog circuits (e.g., ADCs, RF front-ends). |
| Quiescent Current | 49µA (one LDO enabled) - Extends battery life in always-on subsystems like real-time clocks or sensor interfaces. |
| Dropout Voltage @ 150mA | 120mV (for VOUT ≥ 2.8V) - Supports operation with minimal headroom, e.g., 2.5V output from 2.62V input. |
| Output Noise (10Hz–100kHz) | 25µVRMS - Meets stringent low-noise requirements for precision analog signal chains. |
| Operating Temperature Range | –40°C to +85°C - Qualified for industrial and portable consumer environments including medical handhelds. |
Pinout & Package
ISL9016IRUFWZ-T is housed in a 1.6mm × 1.6mm, 6-lead µTDFN package with exposed thermal pad (E-Pad) requiring connection to PCB ground plane for thermal and electrical integrity.
| 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; must connect directly to PCB ground plane and E-Pad. |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic input; 100kΩ pull-up required; enables/disables VOUT2 independently of VOUT1. |
| VOUT1 (Pin 6) | LDO1 Regulated Output | Delivers fixed 2.5V at up to 150mA; requires 1µF–4.7µF ceramic capacitor to GND near pin. |
| VOUT2 (Pin 5) | LDO2 Regulated Output | Delivers fixed 1.2V at up to 150mA; decoupling capacitor placement critical for transient response. |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic input; independent of EN2; allows staggered power-up sequencing between domains. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow precise power sequencing-e.g., enable 1.2V core before 2.5V I/O to prevent latch-up in microcontrollers. |
| Reverse current protection | Blocks >99.9% of backflow from VOUT to VIN when input is grounded or floating, protecting upstream sources. |
| Soft-start ramp rate | 30–60µs/V prevents inrush current spikes during startup, reducing stress on input capacitors and source impedance. |
| Stability with low-ESR ceramics | Operates reliably with 1µF–4.7µF X5R/X7R MLCCs (ESR ≤ 200mΩ), eliminating need for costly tantalum or polymer caps. |
| Thermal shutdown hysteresis | Shuts down at 145°C and re-enables at 110°C-prevents thermal cycling while allowing recovery after transient overload. |

FAQ
What are the fixed output voltages of the ISL9016IRUFWZ-T?
The ISL9016IRUFWZ-T has factory-trimmed fixed outputs: VOUT1 = 2.5V and VOUT2 = 1.2V. These values are confirmed in the Ordering Information table (Page 3) of the FN6832 datasheet and do not require external resistors. This configuration simplifies layout and improves accuracy versus adjustable alternatives. The ISL9016IRUFWZ-T maintains ±0.8% output voltage accuracy across load and temperature.
Does the ISL9016IRUFWZ-T support independent enable control for each LDO?
Yes, the ISL9016IRUFWZ-T provides fully independent enable control via EN1 (controls VOUT1) and EN2 (controls VOUT2). Each pin is active-high with VIH ≥ 1.1V and VIL ≤ 0.4V. A 100kΩ pull-up resistor is recommended per pin to ensure reliable logic levels. This allows precise power sequencing-for example, enabling the 1.2V core before the 2.5V I/O rail in microcontroller applications-without affecting the other channel.
What is the minimum and maximum input voltage range for the ISL9016IRUFWZ-T?
The ISL9016IRUFWZ-T operates over an input voltage range of 1.8V to 6.5V, as specified in the Recommended Operating Conditions (Page 4). This wide range supports direct connection to single-cell Li-ion (2.7–4.2V), Li-SOCl₂ (3.6V), or multi-cell alkaline/NiMH sources. Operation below 1.8V risks UVLO activation (VUV+ = 1.775V max), while exceeding 6.5V violates absolute maximum ratings and may cause permanent damage.
How does the ISL9016IRUFWZ-T handle reverse current flow from output to input?
The ISL9016IRUFWZ-T integrates reverse current protection that limits VOUT-to-VIN leakage to <8µA (typical) when VIN = 0V and VOUT = 5.5V. This feature activates automatically when VOUT exceeds VIN, preventing battery drain in scenarios where the output is externally held high (e.g., by another supply) while VIN is disconnected or grounded. It eliminates the need for external blocking diodes, reducing cost and forward voltage drop.
What package type and thermal characteristics does the ISL9016IRUFWZ-T use?
The ISL9016IRUFWZ-T uses a 6-lead 1.6mm × 1.6mm µTDFN package (PKG DWG. # L6.1.6x1.6A) with an exposed thermal pad (E-Pad) that must be soldered to the PCB ground plane. Its junction-to-ambient thermal resistance (θJA) is 117.5°C/W in free air. Thermal shutdown triggers at +145°C and recovers at +110°C, providing hysteresis to prevent oscillation during overload conditions.
