Product details
Overview
ISL9016IRUGWZ-T from Intersil is a dual low-dropout linear regulator IC delivering 150mA per channel with output voltages of 2.7V (VOUT1) and 1.2V (VOUT2), operating from 1.8V to 6.5V input, featuring 80dB PSRR at 1kHz, 25µVRMS output noise, and <1µA shutdown current. It serves as a precision dual-rail power supply for baseband processors and RF subsystems in portable consumer electronics.
For engineers reviewing the ISL9016IRUGWZ-T datasheet, ISL9016IRUGWZ-T pinout, ISL9016IRUGWZ-T application, or ISL9016IRUGWZ-T equivalent, key selection criteria include independent enable control per LDO, reverse current protection, soft-start timing, dropout voltage at 150mA load, and stability with 1µF ceramic output capacitors.
Technical Context
The ISL9016IRUGWZ-T integrates two independent LDO regulators with separate EN1/EN2 control logic, bandgap references, thermal shutdown (145°C trip), and reverse current protection that activates when VOUT > VIN. Each LDO employs internal current limiting (265mA typical) and soft-start (30–60 µs/V ramp rate) to manage inrush during enable.
Its architecture supports simultaneous or staggered activation of both outputs, with quiescent current scaling from 49µA (single LDO active) to 80µA (dual active), and sub-1µA shutdown draw. Stability is guaranteed across 1µF–4.7µF ceramic output capacitors with ESR ≤200mΩ, eliminating need for tantalum or electrolytic types.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Pair | VOUT1 = 2.7V, VOUT2 = 1.2V - fixed dual-rail configuration for processor core + I/O supply separation |
| Max Output Current | 150mA per channel - sufficient for low-power microcontrollers, sensors, and RF front-end biasing |
| PSRR @ 1kHz | 80dB - suppresses switching noise from upstream DC/DC converters feeding the LDO input |
| Output Noise | 25µVRMS (10Hz–100kHz) - enables clean analog/RF supply without additional filtering |
| Dropout Voltage | 120mV @ 150mA (for VO ≥ 2.8V) - ensures regulation down to VIN = 2.82V for VOUT1 = 2.7V rail |
| Quiescent Current | 49µA (one LDO enabled) - extends battery life in always-on sensor or standby modes |
| Shutdown Current | <1µA - critical for long-term storage or deep-sleep states in portable devices |
Pinout & Package
ISL9016IRUGWZ-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) requiring connection to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO Input Supply | Accepts 1.8V–6.5V input; requires 1µF ceramic capacitor to GND for stability and transient response |
| GND (Pin 2) | System Ground Reference | Common return path for both LDOs; must connect directly to PCB ground plane and E-Pad |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic; 100kΩ pull-up required; enables/disables VOUT2 independently of VOUT1 |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic; 100kΩ pull-up required; enables/disables VOUT1 independently of VOUT2 |
| VOUT2 (Pin 5) | LDO2 Regulated Output | Delivers fixed 1.2V at up to 150mA; connects to 1–4.7µF ceramic capacitor to GND |
| VOUT1 (Pin 6) | LDO1 Regulated Output | Delivers fixed 2.7V at up to 150mA; connects to 1–4.7µF ceramic capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enable control | EN1 and EN2 allow sequenced or isolated power-up/down of 2.7V and 1.2V rails without external logic |
| Reverse current protection | Prevents backflow from 1.2V or 2.7V outputs into VIN when input is grounded or floating - critical for multi-rail hot-swap scenarios |
| Soft-start ramp rate | 30–60 µs/V limits inrush current during enable, reducing stress on input capacitors and upstream supplies |
| Thermal shutdown with hysteresis | Shuts down LDO(s) sourcing >50mA at 145°C; auto-restarts at ~110°C - protects against sustained overload without latch-off |
| ±0.8% output accuracy (25°C) | Meets tight tolerance requirements for core voltage regulation in low-power MCUs and RF ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F12-27QDBVRQ1 | Automotive-grade AEC-Q100 qualified; fixed 1.2V/2.7V outputs; 200mA per channel; higher IQ (65µA single-channel) | Designed for automotive infotainment and ADAS modules requiring extended temperature and reliability validation | Choose for automotive deployments where AEC-Q100 compliance and -40°C to +125°C operation are mandatory |
| MCP1826S-2702702D | Fixed 2.7V/2.7V dual outputs; 300mA per channel; no reverse current protection; 85µA IQ (dual active) | Targeted at cost-sensitive industrial controllers needing matched dual rails but no rail isolation or backflow prevention | Choose when identical dual 2.7V rails suffice and reverse current blocking is not required |

FAQ
What are the fixed output voltages of the ISL9016IRUGWZ-T?
The ISL9016IRUGWZ-T provides fixed output voltages of 2.7V on VOUT1 and 1.2V on VOUT2, as defined by its ordering code suffix "GWZ-T". These values are factory-trimmed and non-adjustable; no external feedback resistors are used. The ISL9016IRUGWZ-T maintains ±0.8% accuracy at 25°C and ±1.8% across –40°C to +85°C, ensuring reliable operation in portable device environments.
Does the ISL9016IRUGWZ-T require external capacitors, and what type is recommended?
Yes, the ISL9016IRUGWZ-T requires an input capacitor (1µF ceramic, X5R/X7R) on VIN and individual output capacitors (1µF to 4.7µF, X5R/X7R) on VOUT1 and VOUT2. These must be placed close to the pins with low-inductance ground connections. The ISL9016IRUGWZ-T is stable with ESR up to 200mΩ, eliminating need for specialized low-ESR types - standard MLCCs meet all stability requirements.
How does reverse current protection function in the ISL9016IRUGWZ-T?
Reverse current protection in the ISL9016IRUGWZ-T activates automatically when VOUT exceeds VIN - such as when input is grounded or floating while output remains biased. Under this condition, the ISL9016IRUGWZ-T limits reverse current to <8µA (typical) from either VOUT1 or VOUT2 to VIN. This prevents unintended discharge of backup supplies and cross-rail interference in multi-power-domain systems.
What is the thermal shutdown behavior of the ISL9016IRUGWZ-T?
The ISL9016IRUGWZ-T triggers thermal shutdown at approximately +145°C (TSD+) and re-enables outputs once die temperature falls to ~+110°C (TSD–). Crucially, only LDOs sourcing >50mA are disabled during overtemperature events - allowing one rail to remain active if its load is light. This selective shutdown preserves partial functionality in thermally stressed conditions, unlike full-device latch-off architectures.
Can the ISL9016IRUGWZ-T operate with input voltage below 2.7V while regulating 2.7V output?
No - the ISL9016IRUGWZ-T cannot regulate 2.7V on VOUT1 with VIN < 2.82V due to its dropout specification: 120mV typical at 150mA for VO ≥ 2.8V. At lighter loads, dropout decreases, but minimum functional VIN remains VO + VDO(min). For reliable 2.7V regulation, VIN must be ≥2.82V (2.7V + 120mV); operation below this risks dropout and output collapse, especially under dynamic load.
