Product details
Overview
ISL9016IRUJBZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs with fixed voltages of 2.8V (VOUT1) and 1.5V (VOUT2), operating from 1.8V to 6.5V input, featuring 80dB PSRR at 1kHz, 25µVRMS output noise, and 120mV dropout at 150mA for VOUT ≥ 2.8V - used in portable medical handhelds and smartphone power rail sequencing.
For engineers reviewing the ISL9016IRUJBZ-T datasheet, ISL9016IRUJBZ-T pinout, ISL9016IRUJBZ-T application, or ISL9016IRUJBZ-T equivalent, key selection criteria include per-channel enable control, reverse current protection, ±0.8% output accuracy over temperature, stable operation with 1µF–4.7µF ceramic capacitors, and µTDFN package thermal performance.
Technical Context
The ISL9016IRUJBZ-T integrates two independent LDO regulators with separate EN1/EN2 logic-level enable inputs, each implementing soft-start ramp control (30–60 µs/V) and fast load transient response via adaptive biasing. It uses internal bandgap references (VREF1/VREF2/VREF3) and thermal sensing to coordinate shutdown at 145°C with hysteresis down to 110°C.
Protection architecture includes per-LDO current limiting (typ. 265mA), reverse current blocking (<8µA when VIN = 0V, VOUT = 5.5V), and undervoltage lockout (VUV+ = 1.775V). Stability is guaranteed with 1µF–4.7µF X5R/X7R ceramic output capacitors having ESR ≤ 200mΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | VOUT1 = 2.8V, VOUT2 = 1.5V - fixed, factory-set outputs eliminating external resistor networks |
| Max Output Current | 150mA per channel - supports dual-rail powering of RF transceivers and baseband processors |
| PSRR | 80dB @ 1kHz, 45dB @ 1MHz - suppresses switching noise from upstream DC-DC converters |
| Quiescent Current | 49µA (single LDO enabled), 80µA (both enabled) - extends battery life in always-on sensor subsystems |
| Dropout Voltage | 120mV @ 150mA for VOUT ≥ 2.8V - enables high-efficiency regulation from low headroom sources like single-cell Li-ion |
| Output Noise | 25µVRMS (10Hz–100kHz) - meets low-noise analog supply requirements for ADCs and RF front-ends |
| Accuracy | ±0.8% at +25°C, ±1.8% over –40°C to +85°C - ensures reliable voltage margining for core logic and memory I/O |
Pinout & Package
ISL9016IRUJBZ-T is housed in a Pb-free, RoHS-compliant 6-lead ultra-thin dual flat no-lead (µTDFN) package measuring 1.6mm × 1.6mm × 0.5mm with exposed thermal pad (E-Pad) requiring connection to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | LDO Input Supply | Common input rail (1.8V–6.5V); requires 1µF ceramic decoupling capacitor to GND |
| GND | System Ground Reference | Primary return path for both LDOs and internal circuitry; must connect directly to E-Pad and PCB ground plane |
| EN2 | LDO2 Enable Control | Active-high digital input; 100kΩ pull-up required; disables VOUT2 independently without affecting VOUT1 |
| EN1 | LDO1 Enable Control | Active-high digital input; 100kΩ pull-up required; enables/disables VOUT1 independently |
| VOUT2 | 1.5V Regulated Output | Supplies 150mA max to low-voltage peripherals; requires 1µF–4.7µF ceramic capacitor to GND |
| VOUT1 | 2.8V Regulated Output | Supplies 150mA max to higher-voltage subsystems; requires 1µF–4.7µF ceramic capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1 and EN2 allow staggered power-up/down sequencing between 2.8V and 1.5V rails for reduced inrush and system-level timing control |
| Reverse current protection | Blocks >99.9% of backfeed current (typ. <8µA) when VOUT > VIN - critical for hot-swap and battery-backup scenarios |
| Soft-start ramp rate | 30–60 µs/V linear ramp prevents input current surges during enable, easing demands on upstream power sources |
| Thermal shutdown with hysteresis | Shuts down LDO(s) sourcing >50mA at 145°C; auto-restarts at 110°C - preserves functionality of unaffected channel 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 alternatives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D2815MR-G | Same 2.8V/1.5V output pair, but 100mA per channel and 200mV dropout at 100mA; no reverse current protection | Suitable only for non-battery-backup or non-hot-swap systems where backfeed risk is absent | Select when cost sensitivity outweighs need for reverse current blocking and higher current capability |
| Ricoh RP512K2815-TR | 2.8V/1.5V outputs, 200mA per channel, 150mV dropout, but lacks soft-start and has 120µA quiescent current (both enabled) | Better for high-current digital loads but less optimal for battery-critical analog subsystems | Prefer when peak load exceeds 150mA and soft-start is not required for system timing compliance |
Compared with XC6216D2815MR-G and RP512K2815-TR, the ISL9016IRUJBZ-T uniquely combines 150mA per channel, reverse current protection, soft-start, and sub-100µA dual-LDO quiescent current - making it the only option qualified for battery-backed portable medical and premium smartphone subsystems demanding simultaneous low noise, low IQ, and fault resilience.

FAQ
What are the fixed output voltages of the ISL9016IRUJBZ-T?
The ISL9016IRUJBZ-T is factory-configured with VOUT1 = 2.8V and VOUT2 = 1.5V. These values are laser-trimmed during production and cannot be adjusted externally. Both outputs deliver up to 150mA continuously and maintain ±0.8% accuracy at +25°C, with full-range tolerance of ±1.8% from –40°C to +85°C. This fixed pairing eliminates external feedback resistors and simplifies layout for dual-rail applications such as smartphone baseband and portable medical devices.
Does the ISL9016IRUJBZ-T require external capacitors, and what types are recommended?
Yes, the ISL9016IRUJBZ-T requires external ceramic capacitors: a 1µF input capacitor (X5R or X7R) on VIN, and individual 1µF–4.7µF output capacitors on VOUT1 and VOUT2. The datasheet specifies compatibility with ESR up to 200mΩ, enabling use of low-cost, small-footprint multilayer ceramics instead of higher-ESR alternatives. Placement must be adjacent to the device pins with direct GND connections to minimize loop inductance and ensure stability under fast load transients.
How does the enable functionality work on the ISL9016IRUJBZ-T?
The ISL9016IRUJBZ-T features two independent active-high enable pins: EN1 controls VOUT1 (2.8V) and EN2 controls VOUT2 (1.5V). Each pin requires a 100kΩ pull-up resistor to a valid logic rail; floating pins are prohibited. When an EN pin transitions high, its corresponding LDO initiates soft-start (30–60 µs/V ramp). When pulled low, that LDO shuts down, drawing <1µA total device current if both EN pins are low. This allows precise power sequencing and dynamic rail gating in battery-sensitive designs.
What protection features does the ISL9016IRUJBZ-T include?
The ISL9016IRUJBZ-T integrates four key protections: (1) reverse current protection (<8µA typical when VIN = 0V, VOUT = 5.5V), (2) thermal shutdown with hysteresis (trip at +145°C, restart at +110°C), (3) per-LDO current limiting (typ. 265mA), and (4) undervoltage lockout (VUV+ = 1.775V). These operate autonomously without external components and preserve functionality of the unaffected LDO during fault conditions - a critical advantage in dual-rail systems where one rail may overload while the other remains operational.
Is the ISL9016IRUJBZ-T compatible with lead-free reflow processes?
Yes, the ISL9016IRUJBZ-T is Pb-free and RoHS-compliant, using a tin-bismuth e6 termination finish compatible with both SnPb and Pb-free soldering profiles. Its 6-lead µTDFN package (L6.1.6x1.6A) is rated for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Moisture sensitivity level (MSL) is defined in the device information page and aligns with industry-standard handling requirements for surface-mount assembly.
