Product details
Overview
ISL9016IRUMWZ-T from Intersil is a dual-channel low-dropout linear regulator IC delivering 150mA per channel with output voltages of 3.0V (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-designed for power sequencing in portable medical handhelds and battery-powered smart devices.
For engineers reviewing the ISL9016IRUMWZ-T datasheet, ISL9016IRUMWZ-T pinout, ISL9016IRUMWZ-T application, or ISL9016IRUMWZ-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 ISL9016IRUMWZ-T integrates two independent LDO regulators sharing a common VIN and GND, each with dedicated EN1/EN2 control, soft-start ramp rate of 30–60µs/V, and separate current limit (265mA typical) and thermal shutdown circuitry. Its bandgap reference and control logic enable fast load transient response with <100mV undershoot under 150mA step loads.
Reverse current protection activates automatically when VOUT > VIN, limiting reverse leakage to <8µA at VOUT = 5.5V and VIN = 0V. The device remains stable across –40°C to +85°C ambient with 1µF X5R/X7R ceramic output capacitors having ESR up to 200mΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | VOUT1 = 3.0V, VOUT2 = 1.2V - fixed dual-rail configuration for core/peripheral supply separation |
| Max Output Current | 150mA per channel - supports moderate-power RF and sensor subsystems without external boost |
| 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 monitoring modes |
| Dropout Voltage | 120mV @ 150mA (VOUT ≥ 2.8V) - enables regulation from 3.12V input to 3.0V rail with margin |
| Output Noise | 25µVRMS (10Hz–100kHz) - meets low-noise analog supply requirements for ADCs and RF front-ends |
| Thermal Shutdown | +145°C activation, +110°C recovery - protects against sustained overload without latch-up |
Pinout & Package
ISL9016IRUMWZ-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 | Common input for both regulators; requires 1µF ceramic capacitor to GND for stability |
| GND (Pin 2) | System Ground Reference | Primary ground return path; e-pad must be soldered to PCB ground plane |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic; 100kΩ pull-up required; disables VOUT2 independently |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic; 100kΩ pull-up required; disables VOUT1 independently |
| VOUT2 (Pin 5) | LDO2 Regulated Output | 1.2V fixed output; connects to 1–4.7µF ceramic capacitor for transient response |
| VOUT1 (Pin 6) | LDO1 Regulated Output | 3.0V fixed output; decoupling capacitor placement critical for noise-sensitive loads |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered power-up/down sequencing between 3.0V and 1.2V rails |
| Reverse current protection | Blocks >99.9% reverse conduction when VOUT > VIN - prevents backfeed in multi-rail systems |
| Soft-start ramp rate | 30–60µs/V limits inrush current during enable - avoids input voltage droop on shared supplies |
| Stable with low-ESR ceramics | Operates reliably with 1–4.7µF X5R/X7R capacitors (ESR ≤ 200mΩ) - eliminates need for tantalum |
| Load transient response | <100mV undershoot for 150mA load steps - maintains regulation during burst-mode processor activity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F3012PDBVR | Fixed 3.0V/1.2V outputs; 200mA per channel; 55dB PSRR @ 1MHz; no reverse current protection | Lacks reverse current blocking - unsuitable where VOUT may exceed VIN during battery swap or fault conditions | Choose when higher output current is needed and reverse protection is handled externally |

FAQ
What are the fixed output voltages of the ISL9016IRUMWZ-T?
The ISL9016IRUMWZ-T is factory-configured with VOUT1 = 3.0V and VOUT2 = 1.2V. These values are laser-trimmed and non-adjustable. The ordering code "MW" in ISL9016IRUMWZ-T explicitly denotes this 3.0V/1.2V combination per Intersil's FN6832 datasheet Table on page 3. No external feedback resistors are used or supported.
Does the ISL9016IRUMWZ-T require external capacitors, and what type is recommended?
Yes, ISL9016IRUMWZ-T requires a 1µF ceramic input capacitor (X5R or X7R) on VIN and individual 1–4.7µF ceramic output capacitors on VOUT1 and VOUT2. The datasheet specifies ESR ≤ 200mΩ and mandates direct grounding of capacitor terminals to the GND pin and e-pad. Tantalum or aluminum electrolytic capacitors are not recommended due to instability risk.
How does the reverse current protection function in the ISL9016IRUMWZ-T?
The ISL9016IRUMWZ-T automatically blocks reverse current flow from VOUT to VIN when VOUT exceeds VIN-critical during battery hot-swap or fault conditions. When VIN = 0V and VOUT = 5.5V, reverse leakage is typically <8µA (max 15µA). This protection is inherent to the internal architecture and requires no external components or enable signals.
What is the thermal shutdown behavior of the ISL9016IRUMWZ-T?
The ISL9016IRUMWZ-T initiates thermal shutdown at +145°C (TSD+) and recovers at +110°C (TSD−). During overtemperature events, only LDOs sourcing >50mA are disabled-allowing one rail to remain active if its load is light. Both LDOs restart with soft-start upon cooling. This staged response prevents full system reset during localized thermal stress.
Can the ISL9016IRUMWZ-T operate with input voltage below 1.8V?
No. The absolute minimum input voltage for ISL9016IRUMWZ-T is 1.8V per the Recommended Operating Conditions table (page 4). Below this, UVLO engages: VUV+ = 1.775V (typical) and VUV− = 1.62V (typical), disabling both LDOs until VIN rises above VUV+. Operation below 1.8V violates specification and risks unregulated output or excessive dropout.
