Product details
Overview
ISL9016IRUMCZ-T from Intersil is a dual low-dropout linear regulator IC delivering 150mA per channel with fixed output voltages of 3.0V (VOUT1) and 1.8V (VOUT2), operating from 1.8V to 6.5V input, featuring 80dB PSRR at 1kHz, 25µVRMS output noise, and ±0.8% output voltage accuracy - used in portable medical handhelds and battery-powered smart devices requiring ultra-low quiescent current.
For engineers reviewing the ISL9016IRUMCZ-T datasheet, ISL9016IRUMCZ-T pinout, ISL9016IRUMCZ-T application, or ISL9016IRUMCZ-T equivalent, key selection criteria include dual independent enable control, reverse current protection, soft-start behavior, thermal shutdown thresholds, and stability with 1µF–4.7µF ceramic output capacitors.
Technical Context
The ISL9016IRUMCZ-T integrates two independent LDO regulators sharing a common VIN and GND, each with dedicated EN1/EN2 control logic, bandgap references, and current-limit/thermal-protection circuitry. Its architecture enables fast load transient response (<100µs recovery) and maintains regulation down to 120mV dropout at 150mA for VOUT ≥ 2.8V.
It implements reverse current protection that limits IORLC to <8µA when VIN = 0V and VOUT = 5.5V, and uses soft-start with 30–60µs/V ramp rate to suppress input surge. Undervoltage lockout triggers at VUV+ = 1.775V (typ) and releases at VUV− = 1.62V (typ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (VOUT1/VOUT2) | 3.0V / 1.8V - factory-trimmed fixed outputs; no external feedback required. |
| Max Output Current per Channel | 150mA continuous - supports dual-rail power for baseband + RF subsystems in handhelds. |
| PSRR @ 1kHz / 1MHz | 80dB / 45dB - suppresses switching noise from DC-DC converters feeding VIN. |
| Quiescent Current (Dual Enabled) | 80µA (typ) - enables >1-year battery life in always-on sensor nodes. |
| Dropout Voltage @ 150mA | 120mV (for VOUT1 = 3.0V) - allows operation down to VIN = 3.12V while maintaining regulation. |
| Output Noise (10Hz–100kHz) | 25µVRMS - suitable for powering noise-sensitive analog circuits like ADCs or RF synthesizers. |
| Thermal Shutdown Threshold | +145°C activation / +110°C release - protects against sustained overload without latch-up. |
Pinout & Package
ISL9016IRUMCZ-T is housed in a Pb-free, RoHS-compliant 6-lead µTDFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (E-Pad). The package supports reflow per JEDEC J-STD-020 MSL3 and provides θJA = 117.5°C/W in free air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | LDO Input Supply Rail | Accepts 1.8V–6.5V; requires 1µF X5R/X7R ceramic capacitor to GND for stability. |
| GND (Pin 2) | System Ground Reference | Common return for both LDOs; must connect E-Pad directly to PCB ground plane. |
| EN2 (Pin 3) | LDO2 Enable Control | Active-high logic; 100kΩ pull-up required; disables VOUT2 independently when low. |
| EN1 (Pin 4) | LDO1 Enable Control | Active-high logic; 100kΩ pull-up required; disables VOUT1 independently when low. |
| VOUT2 (Pin 5) | LDO2 Regulated Output | Delivers fixed 1.8V at up to 150mA; stable with 1µF–4.7µF ceramic cap (ESR ≤200mΩ). |
| VOUT1 (Pin 6) | LDO1 Regulated Output | Delivers fixed 3.0V at up to 150mA; same capacitor requirements as VOUT2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable control | EN1/EN2 allow sequenced power-up/down of 3.0V and 1.8V rails without external logic. |
| Reverse current protection | Blocks >99% of backfeed current (IORLC <8µA typ) when VOUT > VIN - critical for multi-rail hot-swap systems. |
| Soft-start ramp rate | 30–60µs/V prevents inrush into downstream capacitance, reducing stress on source supply. |
| Low-noise regulation | 25µVRMS noise enables clean power for precision analog front-ends without added filtering. |
| Thermal foldback behavior | Shuts down only overloaded LDO(s); unaffected channel remains active - improves system fault tolerance. |

| Portable Medical Handhelds | Smartphone Baseband Subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LADGQR | Single 7-channel 150mA LDO array; no dual independent enable; 65dB PSRR @ 1kHz; 40µVRMS noise. | Requires external logic for rail sequencing; lacks reverse current protection; higher noise limits use in RF sections. | Select when consolidating multiple low-current rails onto one die and sequencing is handled externally. |
| MCP1826S-3002-TR | Single 3.0V 500mA LDO; no second output; 70dB PSRR @ 1kHz; 45µVRMS noise; 120µA IQ. | Cannot replace dual-rail function; requires separate 1.8V regulator; higher IQ reduces battery life in always-on mode. | Select only if VOUT2 is supplied by another source and higher current headroom (500mA) is needed for VOUT1. |
Compared with TPL7407LADGQR and MCP1826S-3002-TR, ISL9016IRUMCZ-T uniquely delivers matched dual outputs with independent enable, sub-1µA shutdown, and reverse current blocking - making it irreplaceable in space-constrained, battery-critical dual-rail systems where rail isolation and ultra-low standby power are mandatory.

FAQ
What are the exact output voltages programmed in ISL9016IRUMCZ-T?
The ISL9016IRUMCZ-T is factory-configured with VOUT1 = 3.0V and VOUT2 = 1.8V. These values are laser-trimmed during production and are not adjustable via external resistors. Output voltage accuracy is ±0.8% over temperature and load, confirmed in the Electrical Specifications table on page 4 of FN6832 Rev 1.00.
Does ISL9016IRUMCZ-T require external capacitors, and what are the minimum values?
Yes, ISL9016IRUMCZ-T requires a 1µF X5R or X7R ceramic capacitor on VIN and each VOUT pin. The device is stable with output capacitors ranging from 1µF to 4.7µF and ESR up to 200mΩ. Placement must be adjacent to the pins with direct GND connections, as specified in the "Input and Output Capacitors" section on page 10 of FN6832 Rev 1.00.
How does reverse current protection operate in ISL9016IRUMCZ-T?
In ISL9016IRUMCZ-T, reverse current protection activates automatically when VOUT exceeds VIN - for example, when VIN is grounded and VOUT is held at 5.5V. Under this condition, output-to-input leakage is limited to <8µA (typ), verified per Note 7 on page 5 of FN6832 Rev 1.00. This prevents damage or power loss in hot-swap or multi-supply configurations.
What is the thermal shutdown behavior of ISL9016IRUMCZ-T during overload?
ISL9016IRUMCZ-T initiates thermal shutdown at +145°C (TSD+) and re-enables at +110°C (TSD−). Crucially, only the LDO sourcing >50mA shuts down - the other channel remains operational. This asymmetric shutdown preserves partial functionality during thermal stress, as documented in the "LDO Protections" section on page 9 of FN6832 Rev 1.00.
Can ISL9016IRUMCZ-T be used with input voltage below 1.8V?
No. ISL9016IRUMCZ-T has an absolute minimum input voltage of 1.8V per Recommended Operating Conditions (page 4), and its undervoltage lockout engages below VUV+ = 1.775V (typ). Operation below 1.8V risks unregulated output or failure to start; the device will not regulate VOUT1 = 3.0V unless VIN ≥ 3.12V (3.0V + 120mV dropout), as specified in the Dropout Voltage table.
