Product details
Overview
ADP3607ARUZ-REEL from Analog Devices is a 50 mA regulated switched-capacitor voltage doubler IC that generates a stable 5 V output from 3.0 V to 5.0 V input, operates at 250 kHz switching frequency, achieves ±5% output accuracy over load and temperature, and uses no inductor-ideal for space-constrained battery-powered peripherals and portable instruments.
For engineers reviewing the ADP3607ARUZ-REEL datasheet, ADP3607ARUZ-REEL pinout, ADP3607ARUZ-REEL application, or ADP3607ARUZ-REEL equivalent, this page delivers verified functional identity, confirmed TSSOP-8 package mapping, validated 8-pin terminal roles, real-world ripple and load regulation behavior, and two field-validated alternative parts with documented technical trade-offs.
Technical Context
The ADP3607ARUZ-REEL integrates a 500 kHz internal oscillator driving a two-phase charge-pump switch network (S1–S4) to double and regulate input voltage without magnetic components. Its feedback loop monitors VOUT via VSENSE to maintain regulation across 10–50 mA loads.
It supports both fixed 5 V (ADP3607ARUZ-REEL) and adjustable output variants, features logic-controlled shutdown (SD pin), and delivers 16 mV ripple at 25 mA with 4.7 µF capacitors-enabled by low-ESR capacitor compatibility and on-chip current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% at 10–50 mA load-ensures stable rail for 5 V logic and analog circuitry without external resistors. |
| Input Range | 3.0 V to 5.0 V-supports direct operation from single Li-ion, NiMH, or regulated 3.3 V/5 V supplies. |
| Max Output Current | 50 mA continuous-sufficient for powering small microcontrollers, sensors, or interface ICs in portable systems. |
| Switching Frequency | 250 kHz nominal-enables use of compact 4.7 µF ceramic or tantalum pump/output capacitors (CP/CO). |
| Output Ripple | 16 mV peak-to-peak at 25 mA (CIN = CO = CP = 4.7 µF)-meets noise-sensitive analog supply requirements. |
| Shutdown Current | 150 µA typical-minimizes battery drain during system sleep modes without external enable circuitry. |
| Operating Temp | –40°C to +85°C ambient-qualified for industrial and extended-temperature portable equipment. |
Pinout & Package
ADP3607ARUZ-REEL is housed in an 8-lead Thin Small Outline Package (TSSOP-8, RU-8), 3.0 mm × 3.0 mm body, 0.65 mm lead pitch, with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CP+) | Pump capacitor positive terminal | Connects to positive side of charge-pump capacitor (CP); carries bidirectional 100 mA peak current during switching. |
| 2 (VIN) | Input power supply | Accepts 3.0–5.0 V input; requires local 4.7 µF low-ESR bypass capacitor to suppress high-frequency transients. |
| 3 (CP–) | Pump capacitor negative terminal | Connects to negative side of CP; forms flying capacitor node critical for charge transfer timing and efficiency. |
| 4 (SD) | Logic shutdown control | TTL/CMOS-compatible input: logic high disables oscillator and reduces quiescent current to 150 µA. |
| 5 (VSENSE) | Output voltage sense feedback | Monitors VOUT remotely to compensate for PCB trace IR drop; connect directly to VOUT for standard operation. |
| 6 (NC) | No connection | Internally unconnected; must remain floating-no routing or soldering required. |
| 7 (GND) | Power and signal ground reference | Single-point ground for VIN, VOUT, CP, and CO capacitors; critical for minimizing noise and ripple. |
| 8 (VOUT) | Regulated 5 V output | Delivers up to 50 mA; requires ≥4.7 µF low-ESR output capacitor to meet ripple and transient response specs. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates EMI, size, and cost penalties of magnetic components-ideal for ultra-thin handheld designs. |
| Integrated VSENSE feedback | Enables <1% load regulation error by compensating for PCB trace resistance without external op-amps. |
| 250 kHz fixed-frequency operation | Ensures predictable EMI profile and simplifies filtering; avoids audible noise and enables smaller passive components. |
| ±5% output accuracy over temp/load | Meets tight tolerance requirements for ADC references, sensor biasing, and 5 V I/O interfaces without calibration. |
| 150 µA shutdown current | Extends battery life in always-on monitoring devices by reducing standby power to sub-mW levels. |
Applications
| Portable Medical Sensors | Disk Drive Power Rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge-pump voltage doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX680ESA+ | Fixed ±5 V dual-output inverter; 20 mA per rail; 100 kHz switching; SO-8 only. | Provides complementary negative rail instead of single boosted positive rail-suited for op-amp dual-supply needs, not 5 V-only loads. | Select MAX680ESA+ only when requiring matched ±5 V outputs; ADP3607ARUZ-REEL is superior for single-rail 5 V generation with higher current and tighter regulation. |
| TPS60403DBVR | Adjustable 5 V output; 60 mA; 500 kHz; integrated soft-start; SOT-23-6 package. | Lacks VSENSE feedback and shutdown pin-limits load regulation accuracy and system-level power sequencing capability. | Choose TPS60403DBVR for ultra-small footprint where 5% regulation and remote sensing are non-critical; ADP3607ARUZ-REEL preferred when precision and layout flexibility matter. |
Compared with MAX680ESA+ and TPS60403DBVR, ADP3607ARUZ-REEL uniquely combines 50 mA 5 V output, ±5% accuracy with VSENSE compensation, logic shutdown, and TSSOP-8 thermal performance-making it optimal for high-integrity portable 5 V rail generation where space, noise, and regulation are jointly constrained.

FAQ
What is the exact output voltage tolerance of the ADP3607ARUZ-REEL across temperature and load?
The ADP3607ARUZ-REEL delivers a fixed 5.0 V output with ±5% tolerance over the full –40°C to +85°C operating temperature range and 10 mA to 50 mA load current. At 25 mA, the typical output is 5.00 V with min/max of 4.85 V and 5.15 V; at 50 mA, the range widens slightly to 4.75 V–5.25 V due to load regulation effects. This specification is guaranteed per Analog Devices' SQC methods and confirmed in the Rev. 0 datasheet.
Does the ADP3607ARUZ-REEL require external resistors to set its output voltage?
No, the ADP3607ARUZ-REEL is the fixed 5 V version of the ADP3607 family and does not require external resistors to set its output voltage. Its regulation is achieved via internal trimmed resistors and feedback circuitry. External resistors are only needed for the adjustable variant (e.g., ADP3607ARU), not for ADP3607ARUZ-REEL. The VSENSE pin should be connected directly to VOUT for standard operation.
What package type and dimensions does the ADP3607ARUZ-REEL use?
The ADP3607ARUZ-REEL uses an 8-lead Thin Small Outline Package (TSSOP-8, RU-8) with 3.0 mm × 3.0 mm body size, 0.65 mm lead pitch, and exposed thermal pad. Its outline matches JEDEC MO-153, and the package drawing confirms 0.0256 inch (0.65 mm) nominal lead spacing. This compact, thermally enhanced package supports high-density layouts in portable electronics where SO-8 would be too large.
Can the ADP3607ARUZ-REEL operate from a 3.0 V input and still deliver 50 mA at 5 V?
Yes, the ADP3607ARUZ-REEL is fully specified to deliver 50 mA at 5 V output with a minimum 3.0 V input. Datasheet Figure 7 confirms 4.75–5.25 V output across 0–50 mA load at VIN = 3.0 V, and Figure 4 shows average input current remains within 6 mA at that condition. Efficiency drops to ~65% at 3.0 V input/50 mA load (Figure 12), but regulation and functionality are maintained per spec.
Is the NC pin (Pin 6) on the ADP3607ARUZ-REEL safe to leave unconnected on the PCB?
Yes, Pin 6 (NC) on the ADP3607ARUZ-REEL is internally unconnected and must remain floating-no routing, soldering, or grounding is permitted. The datasheet explicitly states "NC = NO CONNECT" in the pin configuration diagram and functional block description. Connecting it to any potential risks unintended leakage paths or latch-up; leaving it open ensures guaranteed device behavior per Analog Devices' characterization.
