Product details
Overview
ISL9016AIRUWJZ-T from Intersil is a dual low-dropout linear regulator IC delivering two independent 150mA outputs with fixed 1.2V and 2.8V voltages, ultra-low quiescent current (49µA single-channel active), 80dB PSRR at 1kHz, and stable operation with 1µF–4.7µF ceramic output capacitors - deployed in battery-powered portable electronics requiring clean, sequenced power rails.
For engineers reviewing the ISL9016AIRUWJZ-T datasheet, ISL9016AIRUWJZ-T pinout, ISL9016AIRUWJZ-T application, or ISL9016AIRUWJZ-T equivalent, key selection criteria include dual-rail sequencing capability, reverse current protection, thermal shutdown behavior, dropout voltage under 150mA load, and compatibility with space-constrained 1.6mm×1.6mm UTDFN layouts.
Technical Context
The ISL9016AIRUWJZ-T integrates two independent LDO regulators with separate EN1/EN2 enable controls, soft-start circuitry limiting inrush current, and reverse current protection that activates when VOUT exceeds VIN - critical for systems where outputs may be externally biased. Each LDO features internal bandgap reference, current limit (~265mA typ), and thermal shutdown triggered at +145°C.
Its architecture supports wide input range (1.8V–6.5V), maintains ±0.8% output accuracy over temperature, and delivers low-noise regulation (25µVRMS, 10Hz–100kHz) without requiring external compensation. Stability is guaranteed with 1µF–4.7µF X5R/X7R ceramic capacitors having ESR ≤200mΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | 1.2V (VOUT1) and 2.8V (VOUT2) - fixed, non-adjustable; enables direct powering of core logic and I/O rails in compact devices. |
| Max Output Current | 150mA per channel - sufficient for RF transceivers, sensor interfaces, and low-power microcontrollers without thermal derating in 1.6mm×1.6mm package. |
| Quiescent Current | 49µA (one LDO enabled), 80µA (both enabled) - extends battery life in always-on subsystems such as real-time clocks or wake-up controllers. |
| PSRR | 80dB at 1kHz, 45dB at 1MHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Dropout Voltage | 120mV typ at 150mA (for VOUT ≥2.8V) - allows operation down to 1.8V input while maintaining regulated 1.2V/2.8V outputs. |
| Output Noise | 25µVRMS (10Hz–100kHz) - meets noise-sensitive analog circuit requirements (e.g., ADC references, audio codecs) without additional filtering. |
| Enable Thresholds | VIL ≤0.4V, VIH ≥1.1V - compatible with 1.8V/3.3V GPIO control without level-shifting. |
Pinout & Package
ISL9016AIRUWJZ-T is housed in a 6-lead Ultra Thin Dual Flat No-Lead (UTDFN) package measuring 1.6mm × 1.6mm × 0.5mm, with exposed thermal pad connected to GND for enhanced thermal performance (θJA = 117.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO input supply rail | Accepts 1.8V–6.5V; requires 1µF ceramic decoupling capacitor directly to GND to ensure stability and transient response. |
| GND (Pin 2) | Power and signal reference ground | Must connect to PCB ground plane; serves as return path for both LDOs and thermal pad anchor point. |
| EN2 (Pin 3) | LDO2 enable control input | Active-high logic; 100kΩ pull-up recommended; enables independent power sequencing of 2.8V rail. |
| VOUT1 (Pin 6) | LDO1 regulated output (1.2V) | Delivers up to 150mA; requires 1µF–4.7µF ceramic capacitor to GND placed adjacent to pin for optimal transient suppression. |
| VOUT2 (Pin 5) | LDO2 regulated output (2.8V) | Delivers up to 150mA; same capacitor requirements as VOUT1; reverse current protection prevents backfeed when VIN = 0V. |
| EN1 (Pin 4) | LDO1 enable control input | Active-high logic; independent of EN2; allows staggered startup or dynamic rail disable during low-power modes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs with separate enables | Enables precise power sequencing, rail isolation, and dynamic power gating - e.g., keep 1.2V core active while disabling 2.8V I/O during sleep. |
| Reverse current protection | Blocks >99% of backflow (<8µA typical) when VOUT > VIN - essential for hot-swap, multi-rail, or backup-battery configurations. |
| Soft-start ramp rate | 30–60 µs/V - limits inrush current during enable, preventing input rail collapse and reducing stress on upstream DC-DC stages. |
| Thermal shutdown with hysteresis | Shuts down at +145°C, re-enables at +110°C - protects against sustained overload while allowing recovery without system reset. |
| Stability with low-ESR ceramics | Guaranteed stable with 1µF–4.7µF X5R/X7R capacitors (ESR ≤200mΩ) - eliminates need for tantalum or aluminum electrolytics in space-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6216D122MR-G | Single-output 150mA LDO; 1.2V fixed; no second rail or EN2 control; PSRR = 70dB @1kHz. | Suitable only for single-rail systems; cannot replace ISL9016AIRUWJZ-T's dual-rail functionality without adding a second regulator. | Select only if redesign accommodates separate 2.8V supply and simplified enable scheme. |
| Ricoh RP512F281B-TR-F | Dual 200mA LDO; 2.8V/1.2V outputs; higher IQ (120µA both on); no reverse current protection; PSRR = 65dB @1kHz. | Higher output current margin but lacks reverse blocking - unsuitable for systems with externally held outputs or hot-swap operation. | Consider only when reverse current risk is absent and extra 50mA headroom justifies 2.4× higher quiescent draw. |
Compared with XC6216D122MR-G and RP512F281B-TR-F, the ISL9016AIRUWJZ-T uniquely combines dual-rail independence, sub-50µA single-rail IQ, reverse current blocking, and 80dB PSRR - making it irreplaceable in space- and noise-constrained dual-voltage portable designs without compromising safety or runtime.

FAQ
What are the exact output voltages configured in the ISL9016AIRUWJZ-T?
The ISL9016AIRUWJZ-T is factory-configured with VOUT1 = 1.2V and VOUT2 = 2.8V - fixed, non-adjustable outputs verified in the Ordering Information table of FN8865 Rev 0.00. These values are laser-trimmed during production and cannot be modified externally. The ISL9016AIRUWJZ-T does not support adjustable feedback or external resistor networks for voltage setting.
Does the ISL9016AIRUWJZ-T require external compensation components?
No, the ISL9016AIRUWJZ-T is internally compensated and stable with 1µF–4.7µF ceramic output capacitors (X5R/X7R) having ESR ≤200mΩ. No external resistors, capacitors, or feedback networks are needed - simplifying layout and eliminating tuning steps. This is confirmed in the "Stable with 1µF to 4.7µF ceramic output capacitors" feature and Figure 1 typical application diagram.
How does reverse current protection operate in the ISL9016AIRUWJZ-T?
The ISL9016AIRUWJZ-T activates reverse current protection automatically when VOUT exceeds VIN - for example, if VIN is pulled to ground while VOUT remains at 5.5V. Under this condition, reverse leakage is limited to <8µA (typical), as measured in the Electrical Specifications table. This prevents battery drain and cross-rail interference in multi-supply or hot-swap systems.
What is the thermal shutdown behavior of the ISL9016AIRUWJZ-T?
The ISL9016AIRUWJZ-T triggers thermal shutdown at +145°C (TSD+) and re-enables at +110°C (TSD−), providing 35°C hysteresis. During overtemperature events, only LDOs sourcing >50mA are disabled - allowing one rail to remain active if its load is light. This behavior is documented in the Functional Description section and Electrical Specifications table.
Can the ISL9016AIRUWJZ-T operate with an input voltage below 1.8V?
No - the absolute minimum recommended input voltage is 1.8V, per the Recommended Operating Conditions table. Below this, UVLO engages (VUV− = 1.55–1.62V), disabling regulation. Attempting operation at 1.7V risks unregulated output, increased dropout, or erratic enable behavior - all outside guaranteed specifications.
