Product details
Overview
ISL9016IRUJWZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs with fixed 2.8V and 1.2V voltages, ultra-low quiescent current (49µA single-channel active), high PSRR (80dB @ 1kHz), and reverse current protection - designed for power sequencing in space-constrained portable electronics.
For engineers reviewing the ISL9016IRUJWZ-T datasheet, ISL9016IRUJWZ-T pinout, ISL9016IRUJWZ-T application, or ISL9016IRUJWZ-T equivalent, key selection criteria include dual-output voltage pairing, µTDFN-6 package footprint compatibility, load transient response under 150mA step changes, and shutdown current <1µA for battery-backed systems.
Technical Context
The ISL9016IRUJWZ-T integrates two independent LDO regulators with separate EN1/EN2 control logic, soft-start circuitry limiting input surge during enable, and thermal shutdown that disables only the overloaded LDO (≥50mA) while preserving the other channel's operation. Each LDO features internal bandgap reference, current limit (~265mA typ), and reverse current protection activated when VOUT > VIN.
Stability is guaranteed with 1µF–4.7µF ceramic output capacitors (X5R/X7R, ESR ≤200mΩ), and the device operates across 1.8V–6.5V input while maintaining ±0.8% output accuracy at +25°C and ±1.8% over –40°C to +85°C. Dropout voltage is 120mV typ at 150mA for VOUT ≥2.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 2.8V (VOUT1) and 1.2V (VOUT2) - fixed, non-adjustable; enables simultaneous core/peripheral rail generation |
| Max Output Current per Channel | 150mA continuous - supports RF transceivers, sensors, and low-power microcontrollers without external boost |
| Quiescent Current | 49µA (one LDO enabled), 80µA (both enabled) - extends battery life in always-on subsystems |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from DC-DC converters feeding VIN |
| Dropout Voltage | 120mV typ @ 150mA for 2.8V output - allows operation down to 2.92V input, critical for Li-ion discharge tail |
| Output Noise | 25µVRMS (10Hz–100kHz) - suitable for noise-sensitive analog circuits like ADC references or RF bias rails |
| Shutdown Current | <1µA typ - meets ultra-low-power requirements for deep-sleep modes in handheld medical devices |
Pinout & Package
ISL9016IRUJWZ-T is housed in a 1.6mm × 1.6mm, 6-lead µTDFN package (Pb-free, RoHS compliant) with exposed thermal pad connected to GND. The compact footprint supports high-density PCB layouts in portable form factors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO Input Supply | Accepts 1.8V–6.5V; requires 1µF ceramic decoupling to GND; UVLO triggers below 1.55V |
| GND (Pin 2) | System Ground Reference | Common return for both LDOs and thermal pad; must connect directly to PCB ground plane |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic; 100kΩ pull-up required; disables VOUT2 independently without affecting VOUT1 |
| VOUT1 (Pin 6) | 2.8V Regulated Output | Delivers up to 150mA; stable with 1µF–4.7µF ceramic capacitor to GND; soft-start ramp rate 30–60µs/V |
| VOUT2 (Pin 5) | 1.2V Regulated Output | Delivers up to 150mA; same stability and capacitor requirements as VOUT1; reverse current protection active |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic; 100kΩ pull-up required; enables/disables 2.8V rail independently of 1.2V rail |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable controls (EN1/EN2) | Enables flexible power sequencing - e.g., bring up 2.8V rail before 1.2V for I/O initialization, then disable one rail during sleep |
| Reverse current protection | Blocks backfeed from 1.2V or 2.8V outputs into VIN when input is grounded or floating - prevents battery drain in multi-rail systems |
| Soft-start circuitry | Limits inrush current during enable (tEN = 400–600µs to 95% VO); avoids voltage droop on shared input rails |
| Thermal shutdown with selective disable | Shuts down only the LDO sourcing >50mA when die reaches 145°C - preserves functionality of the second rail during overload |
| Stable with low-ESR ceramics | Operates reliably with 1µF–4.7µF X5R/X7R capacitors (ESR ≤200mΩ), eliminating need for costly tantalum or polymer caps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F3330PDSR | Fixed 3.3V/3.0V outputs; higher IQ (120µA dual-active); no reverse current protection | Designed for non-battery systems where input never floats; lacks rail isolation for mixed-voltage sequencing | Choose only if fixed 3.3V/3.0V pair matches system needs and reverse protection is unnecessary |
| MCP1826S-2801202E/DB | Adjustable VOUT1 (2.8V), fixed VOUT2 (1.2V); higher dropout (250mV @ 150mA); 100µA IQ dual-active | Requires external resistors for VOUT1; less efficient at low VIN; larger SOT-23-6 footprint (2.9mm × 1.6mm) | Prefer when adjustable first rail is needed and board area permits larger package |

FAQ
What are the fixed output voltages of the ISL9016IRUJWZ-T?
The ISL9016IRUJWZ-T provides fixed output voltages of 2.8V on VOUT1 and 1.2V on VOUT2. These values are factory-trimmed and non-adjustable. The ordering code 'JW' in ISL9016IRUJWZ-T explicitly denotes the 2.8V/1.2V combination per Intersil's FN6832 datasheet Table "Ordering Information" on page 3. No external feedback resistors are required or supported.
Does the ISL9016IRUJWZ-T support independent enable control for each LDO?
Yes, the ISL9016IRUJWZ-T features fully independent enable pins: EN1 controls the 2.8V LDO (VOUT1) and EN2 controls the 1.2V LDO (VOUT2). Both are active-high with VIH ≥1.1V and require a 100kΩ pull-up resistor per the datasheet Pin Descriptions (page 2). This allows precise power sequencing - for example, enabling VOUT1 before VOUT2 or disabling only one rail during low-power states.
What is the minimum input voltage required for the ISL9016IRUJWZ-T to regulate both outputs?
The ISL9016IRUJWZ-T requires a minimum input voltage of 1.8V to operate, but regulation depends on dropout margin. For the 2.8V output, typical dropout is 120mV at 150mA, so VIN must be ≥2.92V to maintain regulation under full load. For the 1.2V output, dropout is higher (250mV typ for VO ≤2.1V), requiring VIN ≥1.45V - however, the overall device specification mandates VIN ≥1.8V regardless of load. Thus, 1.8V is absolute minimum, but ≥2.92V is required for guaranteed 2.8V regulation at 150mA.
How does reverse current protection work in the ISL9016IRUJWZ-T?
The ISL9016IRUJWZ-T activates reverse current protection automatically when VOUT exceeds VIN - such as when the input is grounded while outputs are held high by external circuitry. In this condition, the device limits reverse current from VOUT2 or VOUT1 into VIN to <8µA (typical) at VOUT = 5.5V, as specified in the "REVERSE CURRENT CHARACTERISTICS" table (page 5). This prevents battery drain and cross-rail interference in multi-supply systems.
What output capacitor values are validated for stability with the ISL9016IRUJWZ-T?
The ISL9016IRUJWZ-T is validated stable with ceramic output capacitors ranging from 1µF to 4.7µF, using X5R or X7R dielectrics with ESR up to 200mΩ. The datasheet specifies 1µF as the recommended minimum value (page 1, "Typical Application Diagram"; page 10, "Input and Output Capacitors"). Larger values within this range improve load transient response but do not affect basic stability - no minimum ESR requirement exists.
