Product details
Overview
ISL9016IRUGCZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs with fixed voltages of 2.7V (VOUT1) and 1.8V (VOUT2), operating from 1.8V to 6.5V input. It features 80dB PSRR at 1kHz, 25µVRMS output noise, ±0.8% output accuracy at +25°C, and reverse current protection - designed for power sequencing in portable medical handhelds and multi-rail mobile SoC subsystems.
For engineers reviewing the ISL9016IRUGCZ-T datasheet, ISL9016IRUGCZ-T pinout, ISL9016IRUGCZ-T application, or ISL9016IRUGCZ-T equivalent, key selection criteria include dual-channel enable control, µTDFN-6 package thermal performance (θJA = 117.5°C/W), low-quiescent-current operation (49µA single-LDO active), and stability with 1µF–4.7µF ceramic output capacitors.
Technical Context
The ISL9016IRUGCZ-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 employs internal bandgap reference, soft-start ramp control (30–60 µs/V), and thermal shutdown activation at +145°C with automatic recovery at +110°C.
It implements reverse current protection that limits VOUT-to-VIN leakage to <8µA when VIN = 0V and VOUT = 5.5V, and includes current limiting (typ. 265mA) per channel. The device remains stable with ceramic output capacitors (1µF–4.7µF, ESR ≤200mΩ) without requiring external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | VOUT1 = 2.7V, VOUT2 = 1.8V - fixed, factory-set dual-rail supply for baseband + RF or core + I/O domains |
| Max Output Current | 150mA per channel - supports moderate-power analog sensors or low-power microcontrollers |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from upstream DC/DC converters |
| Quiescent Current | 49µA (one LDO enabled), 80µA (both enabled) - extends battery life in always-on subsystems |
| Dropout Voltage | 120mV @ 150mA (for VO ≥2.8V) - enables high-efficiency regulation near battery end-of-life (e.g., 2.85V Li-ion) |
| Output Noise | 25µVRMS (10Hz–100kHz) - suitable for noise-sensitive analog circuits like ADC references or RF synthesizers |
| Operating Temp Range | −40°C to +85°C - qualified for industrial and consumer portable equipment environments |
Pinout & Package
ISL9016IRUGCZ-T is housed in a 1.6mm × 1.6mm, 6-lead ultra-thin dual flat no-lead (µTDFN) package with exposed thermal pad (E-Pad) that must be soldered to PCB ground for thermal and electrical integrity. Package drawing code L6.1.6x1.6A complies with JEDEC MO-229.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | LDO Input Supply Rail | Common input for both regulators; requires 1µF ceramic decoupling capacitor to GND |
| 2 - GND | Power Ground Reference | System ground connection point; ties to E-Pad and PCB ground plane |
| 3 - EN2 | LDO2 Enable Control Input | Active-high logic input; must be pulled up via ≥100kΩ resistor - floating prohibited |
| 4 - EN1 | LDO1 Enable Control Input | Independent active-high enable for VOUT1; allows flexible power sequencing |
| 5 - VOUT2 | 1.8V Regulated Output | Delivers up to 150mA; requires 1–4.7µF ceramic capacitor to GND with low-ESR layout |
| 6 - VOUT1 | 2.7V Regulated Output | Delivers up to 150mA; separate output node enables independent load transient response |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered startup/shutdown - critical for FPGA or PMIC-controlled power sequencing |
| Reverse current protection | Blocks >99% of backfeed current (typ. <8µA) when VOUT > VIN - prevents battery drain in partial-power-down states |
| Soft-start ramp rate | 30–60 µs/V limits inrush current during enable - avoids input rail collapse in shared-supply systems |
| Thermal foldback behavior | Shuts down only overloaded LDO(s) above 50mA while preserving other channel - improves system uptime |
| Stability with minimal capacitance | Operates reliably with 1µF X5R/X7R ceramic output caps - reduces BOM count and board area vs. larger electrolytics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F2718PDBVR | Fixed 2.7V/1.8V outputs; 200mA per channel; higher IQ (65µA single-channel); 65dB PSRR @ 1MHz | Higher output current margin but lower PSRR - less effective against high-frequency switching noise | Prefer when load current exceeds 150mA or when board space permits larger 2.9mm × 1.6mm SOT-563 package |
| TPS70245PWPR | Adjustable outputs (via external resistors); 250mA per channel; 190µA IQ (both on); 60dB PSRR @ 1MHz | Requires external feedback network - adds BOM cost and layout complexity vs. fixed-output ISL9016IRUGCZ-T | Choose when voltage flexibility is required across multiple product variants or when higher current headroom justifies added design effort |
Compared with TPL720F2718PDBVR and TPS70245PWPR, the ISL9016IRUGCZ-T offers superior PSRR (80dB @ 1kHz) and lower quiescent current (49µA), making it optimal for noise-critical, battery-constrained portable designs where fixed 2.7V/1.8V rails suffice and minimal footprint is essential.

FAQ
What are the fixed output voltages of the ISL9016IRUGCZ-T?
The ISL9016IRUGCZ-T provides factory-set output voltages of 2.7V on VOUT1 and 1.8V on VOUT2. These values are non-adjustable and optimized for common dual-rail configurations in portable electronics. The part marking "R2" on the device body corresponds to this specific 2.7V/1.8V combination per the Intersil ordering table in FN6832 Rev 1.00.
Does the ISL9016IRUGCZ-T require external components for stability?
Yes - the ISL9016IRUGCZ-T requires a 1µF ceramic input capacitor (X5R/X7R) between VIN and GND, and individual 1µF–4.7µF ceramic output capacitors from each VOUT pin to GND. No series resistance or additional compensation networks are needed; stability is guaranteed within these capacitor specifications and ESR limits (≤200mΩ).
How does reverse current protection function in the ISL9016IRUGCZ-T?
In the ISL9016IRUGCZ-T, reverse current protection activates automatically when VOUT exceeds VIN - such as when input is grounded while output remains biased by another source. Under VIN = 0V and VOUT = 5.5V conditions, reverse leakage is typically <8µA, preventing battery drain or unintended power coupling between rails. This feature is inherent to the internal architecture and requires no external circuitry.
What is the thermal shutdown behavior of the ISL9016IRUGCZ-T?
The ISL9016IRUGCZ-T initiates thermal shutdown at +145°C (TSD+) and recovers automatically at +110°C (TSD−). Crucially, shutdown is per-channel: only the LDO sourcing >50mA is disabled during overtemperature events, allowing the other channel to remain operational - enhancing system resilience in thermally stressed portable deployments.
Can the ISL9016IRUGCZ-T operate with a 1.8V input supplying 1.8V output?
No - the ISL9016IRUGCZ-T cannot sustain regulation at 1.8V input for its 1.8V output due to dropout requirements. At 150mA load, the dropout voltage for 1.8V output is ≥200mV (per VDO2 spec), meaning minimum valid VIN is ~2.0V. For 1.8V output, recommended VIN is ≥2.3V to ensure margin across temperature and process variation.
