Product details
Overview
ISL9016IRUWGZ-T from Intersil is a dual-channel low-dropout linear regulator IC delivering 150mA per output with fixed 1.2V and 2.7V outputs, 80dB PSRR at 1kHz, 25µVRMS output noise, and 120mV dropout at 150mA for the 2.7V rail. It serves as a precision power supply for RF and analog circuitry in space-constrained portable electronics.
For engineers reviewing the ISL9016IRUWGZ-T datasheet, ISL9016IRUWGZ-T pinout, ISL9016IRUWGZ-T application, or ISL9016IRUWGZ-T equivalent, key selection criteria include dual independent enable control, reverse current protection, µTDFN-6 package compatibility, and stable operation with 1µF ceramic output capacitors under load transients.
Technical Context
The ISL9016IRUWGZ-T integrates two independent LDO regulators sharing a common VIN and GND but featuring separate EN1/EN2 inputs and VOUT1/VOUT2 outputs. Each channel employs bandgap-referenced error amplifiers with soft-start ramp control (30–60 µs/V) and thermal foldback limiting.
It implements reverse current protection that activates when VOUT > VIN, limiting reverse leakage to <8µA at 5.5V output with VIN grounded. Protection logic disables individual LDOs above 145°C junction temperature while retaining operation of the unaffected channel down to 110°C recovery threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 1.2V (VOUT1) and 2.7V (VOUT2), fixed and factory-set - eliminates external resistor networks and ensures ±0.8% accuracy over -40°C to +85°C. |
| Max Output Current | 150mA per channel - supports simultaneous powering of core logic and I/O rails in handheld SoC subsystems. |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from adjacent DC/DC converters feeding the VIN rail. |
| Quiescent Current | 49µA (single LDO active), 80µA (both active) - extends battery life in always-on sensor or standby-mode subsystems. |
| Dropout Voltage | 120mV @ 150mA (for 2.7V output) - enables regulation from 2.82V input, compatible with single-cell Li-ion discharge profiles. |
| Output Noise | 25µVRMS (10Hz–100kHz) - meets low-noise requirements for RF receivers, ADC references, and audio codecs. |
| Enable Threshold | VIH = 1.1V min, VIL = 0.4V max - compatible with 1.8V and 3.3V GPIO control without level-shifting. |
Pinout & Package
ISL9016IRUWGZ-T is housed in a 1.6mm × 1.6mm, 0.5mm pitch, 6-lead µTDFN package (Intersil pkg drawing L6.1.6x1.6A) with exposed thermal pad connected to GND. The package is RoHS-compliant, Pb-free, and rated MSL-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO Input Supply Rail | Accepts 1.8V–6.5V input; requires 1µF X5R/X7R ceramic capacitor to GND close to pin for stability and transient response. |
| GND (Pin 2) | Common Ground Reference | System ground connection point; must be tied directly to PCB ground plane and thermal pad for thermal dissipation and noise immunity. |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high digital input; drives VOUT2 only; requires ≥100kΩ pull-up to control rail to prevent floating. |
| VOUT1 (Pin 6) | LDO1 Regulated Output | Delivers fixed 1.2V at up to 150mA; connects to 1–4.7µF ceramic capacitor with ESR ≤200mΩ for stability. |
| VOUT2 (Pin 5) | LDO2 Regulated Output | Delivers fixed 2.7V at up to 150mA; same capacitor requirements as VOUT1; reverse current protected. |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high digital input; drives VOUT1 only; independent of EN2 for flexible power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered startup/shutdown of 1.2V and 2.7V rails-enables precise power sequencing in multi-rail SoC systems. |
| Reverse current protection | Prevents backflow from VOUT2 (2.7V) to VIN when input is grounded or disconnected-critical for battery-backed or hot-swap applications. |
| Soft-start ramp rate | 30–60 µs/V limits inrush current during enable, reducing stress on input capacitors and upstream DC/DC converters. |
| Thermal shutdown with channel isolation | Disables only the overheating LDO (≥145°C) while preserving operation of the other-maintains partial system functionality during thermal overload. |
| Stable with low-ESR ceramics | Operates reliably with 1µF–4.7µF X5R/X7R MLCCs (ESR ≤200mΩ)-eliminates need for costly tantalum or polymer capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F1227PDBVR | Fixed 1.2V/2.7V outputs, 200mA per channel, 50µVRMS noise, 65dB PSRR @ 1kHz, SOT-23-6 package. | Higher output current but lower PSRR and higher noise - suitable where headroom and cost outweigh noise sensitivity. | Select when board space allows larger SOT-23 footprint and 200mA per rail is required. |
| MCP1826S-1202702D | Adjustable outputs (via external resistors), 300mA per channel, 40µVRMS noise, 70dB PSRR @ 1kHz, SOT-23-6. | Requires external feedback network; lacks reverse current protection and independent enable - better for non-battery or fixed-voltage designs. | Choose when output flexibility is prioritized over integration, and reverse current risk is absent. |
Compared with TPL720F1227PDBVR and MCP1826S-1202702D, the ISL9016IRUWGZ-T delivers superior noise performance (25µVRMS vs ≥40µVRMS) and integrated reverse current protection - critical for battery-powered systems with shared or hot-swappable rails.

FAQ
What are the fixed output voltages of the ISL9016IRUWGZ-T?
The ISL9016IRUWGZ-T provides factory-set fixed outputs: VOUT1 = 1.2V and VOUT2 = 2.7V. These values are laser-trimmed during manufacturing and cannot be adjusted externally. Output accuracy is typically ±0.8% at +25°C and ±1.8% across the full -40°C to +85°C operating range, as specified in the FN6832 datasheet.
Does the ISL9016IRUWGZ-T require external components for stability?
Yes, the ISL9016IRUWGZ-T requires a 1µF X5R or X7R ceramic capacitor on VIN to GND and separate 1µF–4.7µF ceramic capacitors on each VOUT pin to GND. These capacitors must have ESR ≤200mΩ. No series resistors or additional compensation networks are needed - the device is internally compensated and stable with this configuration.
How does reverse current protection work in the ISL9016IRUWGZ-T?
The ISL9016IRUWGZ-T monitors the voltage differential between VOUT and VIN. When VOUT exceeds VIN - such as when VIN is grounded while VOUT remains held at 2.7V by external circuitry - the internal protection circuit limits reverse current flow to <8µA (typical). This prevents battery drain and unintended power coupling in multi-rail or hot-swap systems.
What is the thermal shutdown behavior of the ISL9016IRUWGZ-T?
The ISL9016IRUWGZ-T initiates thermal shutdown at approximately +145°C junction temperature. Crucially, it disables only the LDO channel sourcing >50mA, allowing the other channel to remain operational. Recovery occurs automatically at ~+110°C, followed by soft-start. This channel-isolated thermal management preserves partial system functionality during overload conditions.
Can the ISL9016IRUWGZ-T operate from a 1.8V input when regulating 2.7V output?
No. The ISL9016IRUWGZ-T cannot regulate 2.7V output from a 1.8V input because the minimum input voltage must exceed the output voltage by the dropout voltage. At 150mA load, dropout for the 2.7V rail is 120mV (typical), requiring VIN ≥ 2.82V. The absolute minimum VIN specification is 1.8V, but usable input range depends on output voltage and load current.
