Product details
Overview
ADP3607ARU-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 mobile phones and portable instruments.
For engineers reviewing the ADP3607ARU-REEL datasheet, ADP3607ARU-REEL pinout, ADP3607ARU-REEL application, or ADP3607ARU-REEL equivalent, key selection considerations include its TSSOP-8 package, shutdown control via SD pin, VSENSE feedback for improved load regulation, and compatibility with low-ESR ceramic/tantalum pump and output capacitors.
Technical Context
The ADP3607ARU-REEL implements a two-phase charge-pump topology driven by an internal 500 kHz oscillator (yielding 250 kHz effective switching), enabling compact capacitor-based DC/DC conversion without magnetic components. Its internal switch network (S1–S4) alternately charges CP from VIN and transfers charge to CO to double and regulate output voltage.
Regulation is achieved via internal 1.5 V reference and error amplifier comparing VSENSE to VREF; feedback path supports both fixed 5 V (ADP3607ARU-5) and adjustable versions (ADP3607ARU). The SD pin controls oscillator enable/disable, reducing quiescent current to 150 µA in shutdown mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% at 10–50 mA load; enables direct replacement of LDOs in 5 V rail generation. |
| Input Voltage Range | 3.0 V to 5.0 V; supports single-cell Li-ion (3.0–4.2 V) and 3.3 V system rails without external level shifting. |
| Max Output Current | 50 mA continuous; sufficient for powering small microcontrollers, sensors, or RF front-end bias circuits. |
| Switching Frequency | 250 kHz nominal; allows use of 4.7 µF ceramic/tantalum capacitors instead of larger electrolytics or inductors. |
| Load Regulation | 0.25 mV/mA (10–50 mA); ensures <15 mV output shift across full load range, critical for analog sensor interfaces. |
| Shutdown Current | 150 µA typical; reduces system standby power in portable devices with periodic wake-up cycles. |
| Operating Temp | –40°C to +85°C ambient; qualified for industrial and consumer-grade embedded applications. |
Pinout & Package
TSSOP-8 (RU-8) package: 3.0 mm × 3.0 mm body, 0.65 mm pitch, exposed pad optional for thermal relief. Pin 6 is NC; all other pins match SO-8 functional mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CP+) | Pump capacitor positive terminal | Connects to high-side switch node; carries peak current ≈2× IOUT; requires low-ESR capacitor placement adjacent to pin. |
| 2 (VIN) | Positive input supply | Accepts 3.0–5.0 V; must be bypassed with ≥1 µF low-ESR capacitor close to pin to suppress switching transients. |
| 3 (CP–) | Pump capacitor negative terminal | Switches between GND and VIN during charge-transfer phases; forms flying capacitor node with CP+. |
| 4 (SD) | Logic-level shutdown control | High = disable oscillator & reduce IQ to 150 µA; low = normal operation; TTL/CMOS compatible. |
| 5 (VSENSE) | Output voltage sense input | Enables remote sensing to compensate PCB trace IR drop; connect directly to load for best regulation. |
| 6 (NC) | No connection | Not internally bonded; leave unconnected and unpopulated on PCB. |
| 7 (GND) | Power and signal ground | Single-point ground reference for VIN, CP–, VOUT, and VSENSE return paths; critical for ripple suppression. |
| 8 (VOUT) | Regulated 5 V output | Delivers up to 50 mA; requires ≥4.7 µF low-ESR capacitor to GND; output ripple ≤31 mV at 50 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Eliminates EMI, size, and cost penalties of magnetic components-enables ultra-thin portable designs. |
| Integrated 1.5 V reference | Provides stable regulation baseline; combined with external resistor divider (for adjustable version) enables precise VOUT tuning. |
| VSENSE feedback loop | Compensates for up to 100 mΩ PCB trace resistance, maintaining ±5% accuracy at point-of-load. |
| 250 kHz fixed-frequency operation | Ensures predictable EMI profile and simplifies filtering; avoids audible noise common in lower-frequency charge pumps. |
| Thermal protection | Internal junction temperature limit prevents damage under sustained overload or poor PCB thermal design. |

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; 20 mA per rail; 100 kHz switching; SO-8 only | Suitable for dual-rail analog systems but lacks adjustable output and higher current capability | Select MAX680ESA+ only when ±5 V rails are required simultaneously and 20 mA per rail suffices. |
| TPS60403DBVR | Fixed 5 V; 60 mA; 500 kHz; integrated soft-start; SOT-23-6 package | Smaller footprint and higher current, but no VSENSE feedback or shutdown control | Choose TPS60403DBVR for space-constrained designs needing >50 mA, accepting trade-off of reduced regulation precision. |
Compared with ADP3607ARU-REEL, MAX680ESA+ delivers dual polarity but lower current and no load-sense capability, while TPS60403DBVR offers higher current in smaller package but sacrifices VSENSE accuracy and shutdown flexibility-making ADP3607ARU-REEL optimal for precision 5 V point-of-load regulation in TSSOP-8 layouts.

FAQ
What is the maximum output current specification for ADP3607ARU-REEL?
The ADP3607ARU-REEL is rated for 50 mA continuous output current at 5 V with input voltage between 3.0 V and 5.0 V. This value is guaranteed across the full operating temperature range (–40°C to +85°C) and accounts for worst-case load regulation and ripple. Exceeding 50 mA may cause output voltage droop beyond ±5% or thermal shutdown activation.
Does ADP3607ARU-REEL require external resistors to set output voltage?
No-ADP3607ARU-REEL is the fixed 5 V version; it does not require external resistors. The "ARU" suffix denotes TSSOP-8 packaging, and "-5" is implied per Analog Devices' ordering guide (ADP3607ARU-5 = fixed 5 V). External resistors are only needed for the adjustable variant (ADP3607ARU), which uses a resistor between VSENSE and VOUT to set output voltage per VOUT = 9.5 + R (kΩ).
Can ADP3607ARU-REEL operate with input voltage below 3.0 V?
No-ADP3607ARU-REEL has a specified minimum input voltage of 3.0 V. Operation below this threshold is not characterized and may result in failure to regulate, reduced output current capability, or unstable oscillation. The device's internal reference and switch drivers are designed for reliable startup and regulation only within the 3.0 V to 5.0 V range.
What capacitor types are recommended for CP and CO in ADP3607ARU-REEL designs?
Analog Devices recommends low-ESR multilayer ceramic (MLCC) or solid tantalum capacitors for both CP and CO in ADP3607ARU-REEL circuits. MLCCs (e.g., TOKIN MLCC, MuRata GRM) offer superior high-frequency performance and temperature stability; tantalums (e.g., Sprague 675D, Mallory TDC) provide better low-temperature ESR. Aluminum electrolytics are discouraged due to higher ESR and aging effects.
Is ADP3607ARU-REEL pin-compatible with ADP3607AR-REEL?
Yes-ADP3607ARU-REEL (TSSOP-8) and ADP3607AR-REEL (SO-8) share identical pin functions and electrical specifications; only the package differs. Both use the same pinout: CP+, VIN, CP–, SD, VSENSE, NC, GND, VOUT. Mechanical layout must accommodate RU-8's smaller footprint (3.0 × 3.0 mm vs. SO-8's 4.9 × 6.0 mm) and 0.65 mm pitch.
