Product details
Overview
ISL9016IRUKWZ-T from Intersil is a dual-channel low-dropout linear regulator IC delivering 150mA per output with fixed output voltages of 2.85V (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 voltage accuracy at +25°C, and reverse current protection - deployed in battery-powered portable instrumentation and medical handhelds.
For engineers reviewing the ISL9016IRUKWZ-T datasheet, ISL9016IRUKWZ-T pinout, ISL9016IRUKWZ-T application, or ISL9016IRUKWZ-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 ISL9016IRUKWZ-T integrates two independent LDO regulators with separate EN1/EN2 control logic, soft-start ramp rate of 30–60µs/V, and internal bandgap reference with three voltage references (VREF1–VREF3) for precision regulation. Each LDO employs dedicated current-limit circuitry (typ. 265mA) and thermal sensing that disables only the overloaded channel above +145°C.
It implements reverse current protection activated when VOUT > VIN, limiting reverse leakage to <8µA at VOUT = 5.5V and VIN = 0V. The device uses a low-ESR-stable architecture compatible with X5R/X7R ceramic capacitors up to 200mΩ ESR and achieves fast load transient response via adaptive biasing during dynamic load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 2.85V (VOUT1) / 1.2V (VOUT2) - fixed, factory-set outputs enabling dual-rail power for mixed-signal SoCs and RF front-ends. |
| Max Output Current | 150mA per channel - supports simultaneous powering of core logic and I/O peripherals without external current boosting. |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from upstream DC/DC converters in portable systems. |
| Quiescent Current | 49µA (one LDO enabled), 80µA (both enabled) - extends battery life in always-on sensor nodes and standby modes. |
| Dropout Voltage | 120mV @ 150mA (for VO ≥ 2.8V) - enables efficient regulation from low-input sources like single-cell Li-ion (3.0V min). |
| Output Noise | 25µVRMS (10Hz–100kHz) - meets low-noise analog supply requirements for ADCs, audio codecs, and RF synthesizers. |
| Thermal Shutdown | +145°C activation, +110°C recovery - provides autonomous overtemperature protection without system-level intervention. |
Pinout & Package
ISL9016IRUKWZ-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 transient response. |
| GND (Pin 2) | System Ground Reference | Common return path for both LDOs and E-Pad; must connect directly to low-impedance PCB ground plane. |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic input; 100kΩ pull-up required; enables/disables 1.2V output independently of LDO1. |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic input; 100kΩ pull-up required; enables/disables 2.85V output independently of LDO2. |
| VOUT2 (Pin 5) | LDO2 Output (1.2V) | Regulated 1.2V rail; stable with 1µF–4.7µF ceramic capacitor to GND; reverse-current protected. |
| VOUT1 (Pin 6) | LDO1 Output (2.85V) | Regulated 2.85V rail; stable with 1µF–4.7µF ceramic capacitor to GND; reverse-current protected. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered power-up sequencing and selective shutdown of 2.85V/1.2V rails to optimize system-level power states. |
| Reverse current protection | Blocks backflow from VOUT to VIN when input is grounded or floating - critical for multi-rail systems with shared batteries or hot-swap scenarios. |
| Soft-start ramp rate | 30–60µs/V limits inrush current during enable, preventing input voltage droop and avoiding false resets in host microcontrollers. |
| Low-noise regulation | 25µVRMS noise floor ensures clean analog supply for precision sensors and high-SNR signal chains without additional filtering. |
| Thermal foldback behavior | Disables only the overloaded LDO above +145°C while maintaining operation of the other channel - improves system fault tolerance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F3312PDBVR | Fixed 3.3V/1.2V outputs; higher IQ (120µA dual-active); no reverse current protection. | Suitable for cost-sensitive consumer devices where reverse leakage is not critical. | Choose if 3.3V rail is needed instead of 2.85V and PSRR >70dB at 100kHz is acceptable. |
| MCP1826S-28512ST | 2.85V/1.2V outputs; 100mA max per channel; 65dB PSRR @ 1kHz; no independent enables. | Targeted at simpler embedded controllers with shared enable logic. | Choose if load current ≤100mA suffices and board space allows larger SOT-23-6 footprint. |
Compared with TPL720F3312PDBVR and MCP1826S-28512ST, ISL9016IRUKWZ-T delivers superior PSRR (80dB vs ≤65dB), lower noise (25µVRMS vs ≥40µVRMS), and true independent enable control - making it optimal for high-fidelity portable instrumentation where rail isolation and transient immunity are design-critical.

FAQ
What are the fixed output voltages of the ISL9016IRUKWZ-T?
The ISL9016IRUKWZ-T has factory-trimmed fixed outputs: VOUT1 = 2.85V and VOUT2 = 1.2V. These values are confirmed in the Ordering Information table (Page 3, FN6832 Rev 1.00) and are not adjustable via external resistors. Both outputs maintain ±0.8% accuracy at +25°C and ±1.8% over –40°C to +85°C ambient range. This dual-rail configuration supports mixed-voltage SoCs without external feedback networks.
Does the ISL9016IRUKWZ-T require external capacitors, and what are the specifications?
Yes, ISL9016IRUKWZ-T requires external ceramic capacitors: a 1µF input capacitor (X5R/X7R) on VIN and 1µF–4.7µF output capacitors on VOUT1 and VOUT2. Per Page 10 of FN6832, these must have ESR ≤200mΩ. The ground connections must tie directly to the GND pin and be placed adjacent to the µTDFN package. No tantalum or electrolytic capacitors are recommended due to ESR and stability constraints.
How does the reverse current protection function in the ISL9016IRUKWZ-T?
The ISL9016IRUKWZ-T activates reverse current protection automatically when VOUT exceeds VIN - such as when the input is grounded while the output remains biased by another supply. As specified on Page 5 (Note 7), reverse leakage is limited to <8µA (typical) at VOUT = 5.5V and VIN = 0V. This prevents unintended battery discharge and protects upstream power sources in multi-rail architectures.
What is the thermal shutdown behavior of the ISL9016IRUKWZ-T?
The ISL9016IRUKWZ-T initiates thermal shutdown at +145°C (TSD+) and recovers at +110°C (TSD–). Crucially, Page 9 confirms it disables *only the overloaded LDO* - if only VOUT1 draws >50mA under overtemperature, VOUT2 continues regulating. This channel-level foldback preserves partial system functionality during thermal stress, unlike monolithic shutdown schemes.
Can the ISL9016IRUKWZ-T operate with a 1.8V input supply?
Yes, ISL9016IRUKWZ-T supports VIN as low as 1.8V, per Absolute Maximum Ratings (Page 4) and Recommended Operating Conditions (Page 4). At 1.8V input, it can sustain 150mA on the 1.2V output (dropout = 120mV typ.), but cannot deliver full current to the 2.85V output - which requires VIN ≥ 2.97V (2.85V + 120mV) for 150mA. System designers must verify minimum input headroom per output rail.
