Product details
Overview
ISL9016IRUMKZ-T from Intersil is a dual 150mA low-dropout linear regulator with independent enable control, delivering 3.0V and 2.85V outputs. It features 80dB PSRR at 1kHz, 25µVRMS output noise, and 120mV dropout at 150mA for the 2.85V rail-designed for noise-sensitive RF and analog circuitry in portable medical handhelds and smartphones.
For engineers reviewing the ISL9016IRUMKZ-T datasheet, ISL9016IRUMKZ-T pinout, ISL9016IRUMKZ-T application, or ISL9016IRUMKZ-T equivalent, key selection criteria include dual-rail voltage pairing (3.0V/2.85V), µTDFN-6 package footprint compatibility, reverse current protection under VOUT > VIN, and sub-1µA shutdown current for battery longevity.
Technical Context
The ISL9016IRUMKZ-T integrates two independent LDO regulators sharing a common VIN and GND, each with dedicated EN pins (EN1, EN2) enabling asynchronous power sequencing. Its bandgap reference and thermal-sensing circuitry support ±0.8% output accuracy over –40°C to +85°C and automatic thermal shutdown at +145°C.
It employs soft-start ramp control (30–60 µs/V) and fast load transient response (<1ms recovery) enabled by internal bias optimization. Reverse current protection limits IORLC to <8µA when VIN = 0V and VOUT = 5.5V, preventing backfeed in multi-rail systems where outputs may be held high while input is removed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.0V (VOUT1) and 2.85V (VOUT2); fixed, factory-set for simultaneous powering of core logic and RF/analog subsystems. |
| Max Output Current | 150mA per channel; supports moderate-power microcontrollers and sensors without external boost stages. |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz; suppresses switching noise from upstream DC/DC converters feeding noisy digital rails. |
| Dropout Voltage | 120mV typical @ 150mA for 2.85V output; enables operation from 3.0V input with ≥170mV headroom, critical for Li-ion battery discharge profiles. |
| Quiescent Current | 49µA (single LDO active), 80µA (both active); extends battery life in always-on sensor monitoring modes. |
| Output Noise | 25µVRMS (10Hz–100kHz); meets low-noise requirements for ADC references and RF synthesizer VCO supplies. |
| Shutdown Current | <1.0µA max; ensures negligible drain during deep sleep in portable medical devices. |
| Stability Range | Stable with 1µF–4.7µF ceramic output capacitors (X5R/X7R, ESR ≤200mΩ); eliminates need for large tantalum or electrolytic caps. |
Pinout & Package
ISL9016IRUMKZ-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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | LDO input supply rail | Accepts 1.8V–6.5V; requires 1µF ceramic decoupling capacitor directly to GND to suppress input ripple and ensure stability. |
| 2 - GND | Common system ground reference | Must connect to PCB ground plane; serves as return path for both LDOs and thermal pad anchor point. |
| 3 - EN2 | LDO2 enable control input | Active-high logic; requires pull-up resistor (≥100kΩ) to avoid floating state; controls 2.85V output independently. |
| 4 - EN1 | LDO1 enable control input | Active-high logic; enables/disables 3.0V output separately; allows staggered power-up sequences for SoC subsystems. |
| 5 - VOUT2 | 2.85V regulated output | Delivers up to 150mA; connects to 1µF–4.7µF ceramic capacitor to GND; low-noise rail for RF front-end ICs. |
| 6 - VOUT1 | 3.0V regulated output | Delivers up to 150mA; stable with same capacitor range; powers core logic, memory, or MCU I/O banks. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enable control | EN1 and EN2 allow precise sequencing of 3.0V and 2.85V rails-critical for avoiding latch-up in mixed-voltage SoCs. |
| Reverse current protection | Blocks >99% of backfeed current (<8µA typical) when VOUT exceeds VIN, protecting upstream DC/DC converters during hot-swap or partial power-down. |
| Soft-start ramp rate | 30–60 µs/V limits inrush current during enable, preventing input voltage sag that could reset adjacent circuits. |
| Thermal shutdown with hysteresis | Shuts down LDO(s) sourcing >50mA at +145°C; re-enables automatically at +110°C-enables safe recovery without system reset. |
| Low-noise, high-PSRR regulation | 25µVRMS noise + 80dB PSRR at 1kHz enables clean power for precision analog signal chains without additional filtering. |
| Ultra-small µTDFN-6 footprint | 1.6mm × 1.6mm body with 0.5mm pitch saves >60% board area vs. SOT-23-6, ideal for space-constrained handheld medical devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F3030PDBVR | Fixed 3.0V/3.0V outputs; no voltage asymmetry; 200mA per channel; higher IQ (120µA dual-active). | Suitable only where matched dual rails are acceptable; lacks 2.85V option for RF biasing. | Select if identical voltages simplify BOM and higher current margin is needed; not suitable for asymmetric rail requirements. |
| MCP1826S-300285SK | Same 3.0V/2.85V outputs; 300mA per channel; higher dropout (250mV @ 150mA); larger SOT-23-6 package. | Compatible for space-tolerant designs needing higher current; less efficient at low VIN due to higher dropout. | Choose when >150mA per rail is required and PCB area permits SOT-23-6; verify thermal performance with 117.5°C/W θJA. |
Compared with ISL9016IRUMKZ-T, TPL720F3030PDBVR offers higher current but symmetric outputs unsuited for RF/analog separation, while MCP1826S-300285SK matches the voltage pair but trades off efficiency and footprint for current headroom-making ISL9016IRUMKZ-T optimal for compact, noise-critical dual-rail systems.

FAQ
What are the fixed output voltages of the ISL9016IRUMKZ-T?
The ISL9016IRUMKZ-T provides factory-set output voltages of 3.0V on VOUT1 and 2.85V on VOUT2. These values are non-adjustable and optimized for powering complementary subsystems such as MCU cores and RF/analog components simultaneously. The ISL9016IRUMKZ-T does not support external feedback resistors for voltage adjustment.
Does the ISL9016IRUMKZ-T require external capacitors, and what values are recommended?
Yes, the ISL9016IRUMKZ-T requires ceramic output capacitors of 1µF to 4.7µF (X5R or X7R dielectric, ESR ≤200mΩ) on both VOUT1 and VOUT2, placed close to the pins with direct GND connections. A 1µF input capacitor (X5R/X7R) on VIN is also mandatory for stability and noise suppression. The ISL9016IRUMKZ-T is not stable with tantalum or aluminum electrolytic capacitors.
How does reverse current protection function in the ISL9016IRUMKZ-T?
The ISL9016IRUMKZ-T blocks reverse current flow from VOUT to VIN when VOUT exceeds VIN-such as when the input is grounded or disconnected while outputs remain powered externally. Under VOUT = 5.5V and VIN = 0V, reverse leakage is typically <8µA. This protects upstream power sources and prevents unintended discharge paths in multi-rail systems using the ISL9016IRUMKZ-T.
What is the thermal shutdown behavior of the ISL9016IRUMKZ-T?
The ISL9016IRUMKZ-T initiates thermal shutdown at +145°C junction temperature and recovers automatically at +110°C. Only LDO channels sourcing >50mA are disabled during overtemperature events-allowing one rail to remain active if its load is light. This selective shutdown preserves partial system functionality during thermal stress, a key reliability feature of the ISL9016IRUMKZ-T.
Can the ISL9016IRUMKZ-T operate from a 1.8V input supply?
Yes, the ISL9016IRUMKZ-T supports input voltages from 1.8V to 6.5V. However, with a 1.8V input, the 2.85V output cannot be sustained due to dropout constraints-the minimum input for 2.85V operation is ~3.0V (2.85V + 120mV typical dropout). For 3.0V output, minimum input is ~3.12V. The ISL9016IRUMKZ-T remains functional at 1.8V only if used with lower-output variants-not applicable to this specific part.
