Product details
Overview
ADP3607AR-REEL from Analog Devices is a 50 mA regulated switched-capacitor voltage doubler IC that generates a stable 5 V output from 3.0–5.0 V input without requiring an inductor. It features ±5% output accuracy at 50 mA load, 250 kHz switching frequency, and SO-8 packaging for compact board integration in low-power portable systems.
For engineers reviewing the ADP3607AR-REEL datasheet, ADP3607AR-REEL pinout, ADP3607AR-REEL application, or ADP3607AR-REEL equivalent, key selection criteria include regulated 5 V output capability, shutdown control via SD pin, VSENSE feedback for improved load regulation, low 150 µA shutdown current, and compatibility with 4.7 µF ceramic/tantalum pump and output capacitors.
Technical Context
The ADP3607AR-REEL implements a two-phase charge-pump topology driven by an internal 500 kHz oscillator to produce a 250 kHz switching waveform. Its feedback loop regulates output voltage using internal 1.5 V reference and error amplifier, with VSENSE pin enabling remote sensing to compensate for PCB trace IR drop.
It operates in fixed 5 V output mode (ADP3607AR-5 variant), supports logic-level shutdown (VIH = 2.4 V, VIL = 0.4 V), and delivers up to 50 mA while maintaining ≤31 mV output ripple at full load with 4.7 µF CO and CP capacitors.
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. |
| Output Current | 50 mA maximum - sufficient to power small microcontrollers, sensors, or RF front-ends in battery-constrained devices. |
| Input Voltage Range | 3.0 V to 5.0 V - compatible with single-cell Li-ion (3.0–4.2 V), 3.3 V LDO outputs, and 5 V USB-powered systems. |
| Switching Frequency | 250 kHz nominal - enables use of compact 4.7 µF ceramic/tantalum capacitors instead of bulky electrolytics or inductors. |
| Shutdown Current | 150 µA typical - minimizes battery drain during sleep modes in portable instruments and pagers. |
| Load Regulation | 0.25 mV/mA (10–50 mA) - maintains tight output stability across varying load conditions without external compensation. |
| Operating Temp | –40°C to +85°C ambient - qualified for industrial and automotive accessory environments. |
Pinout & Package
ADP3607AR-REEL is housed in an 8-lead SOIC (SO-8) package with standard 1.27 mm pitch, 5.00 mm × 4.00 mm body size, and exposed pad not present. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CP+) | Pump capacitor positive terminal | Connects to positive lead of 4.7 µF charge pump capacitor; carries bidirectional 100 mA peak current during switching phases. |
| 2 (VIN) | Input supply voltage | Accepts 3.0–5.0 V input; requires local 4.7 µF low-ESR bypass capacitor to suppress high-frequency switching transients. |
| 3 (CP–) | Pump capacitor negative terminal | Connects to negative lead of pump capacitor; forms charge-transfer path with CP+ during phase reversal. |
| 4 (SD) | Logic shutdown control | Apply ≥2.4 V to disable oscillator and reduce quiescent current to 150 µA; tie to GND for normal operation. |
| 5 (VSENSE) | Output voltage sense input | Connect directly to VOUT for standard regulation; route to load point to cancel PCB trace resistance and improve load regulation. |
| 6 (NC) | No connection | Internally unconnected; must remain floating - no routing or soldering permitted. |
| 7 (GND) | Power ground reference | Primary return path for all internal switches and bias circuits; connect to single-point ground near CIN and CO. |
| 8 (VOUT) | Regulated 5 V output | Delivers up to 50 mA; requires 4.7 µF low-ESR output capacitor to limit ripple to ≤31 mV at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless voltage doubling | Eliminates magnetic components and EMI concerns - simplifies layout and reduces BOM count in space-constrained designs. |
| VSENSE remote sensing | Compensates for up to 100 mΩ PCB trace resistance between IC and load, improving load regulation by >5× vs. local sensing. |
| 250 kHz fixed-frequency operation | Enables predictable EMI filtering and consistent capacitor sizing - avoids variable-frequency noise spread in sensitive analog sections. |
| Logic-compatible shutdown | Direct interface with MCU GPIO pins (3.3 V/5 V tolerant) enables precise power sequencing without level-shifting circuitry. |
| ±5% output accuracy over temp/load | Meets requirements for powering ADC references, op-amp rails, and digital I/O without post-regulation LDOs. |

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 output, 20 mA max, 100 kHz switching, SO-8 - lower current rating and slower frequency require larger capacitors. | Limited to ultra-low-power applications (e.g., real-time clocks); insufficient for 50 mA loads like disk drive actuators. | Select MAX680ESA+ only if load current ≤20 mA and board space allows larger 10 µF pump/output caps. |
| TPS60403DBVR | Adjustable 3–5.5 V output, 60 mA, 500 kHz, SOT-23-6 - higher frequency but no VSENSE pin or shutdown control. | Suitable for cost-sensitive consumer electronics where remote sensing and precise shutdown timing are unnecessary. | Choose TPS60403DBVR when footprint reduction is critical and load regulation tolerance >±8% is acceptable. |
Compared with MAX680ESA+ and TPS60403DBVR, ADP3607AR-REEL uniquely combines 50 mA output, VSENSE-based load regulation, and logic-controlled shutdown in SO-8 - making it optimal for industrial portable instruments requiring precision and reliability.

FAQ
What is the output voltage tolerance of the ADP3607AR-REEL over temperature and load?
The ADP3607AR-REEL delivers a fixed 5.0 V output with ±5% tolerance across –40°C to +85°C ambient temperature and 10–50 mA load range. At 25°C and 25 mA load, typical output is 5.00 V with ±0.15 V variation; worst-case deviation remains within 4.75–5.25 V per datasheet specifications.
Can the ADP3607AR-REEL operate from a 3.0 V input while delivering 50 mA at 5 V?
Yes, the ADP3607AR-REEL is fully specified to deliver 50 mA at 5 V output from a 3.0 V input. Its charge-pump architecture maintains regulation down to 3.0 V, with measured output voltage remaining 4.75–5.25 V across the full load and temperature range per Rev. 0 datasheet Table.
How does the VSENSE pin improve performance in the ADP3607AR-REEL?
The VSENSE pin on the ADP3607AR-REEL enables remote output voltage sensing at the load point, compensating for IR drop across PCB traces. When routed directly to the load instead of tying to VOUT, it improves load regulation by up to 5× - reducing voltage deviation from 0.25 mV/mA to <0.05 mV/mA under dynamic load changes.
What capacitor types and values are recommended for the ADP3607AR-REEL?
Analog Devices recommends 4.7 µF low-ESR capacitors for CP (pump), CO (output), and CIN (input), with ceramic (TOKIN MLCC) or solid tantalum (Sprague 675D) preferred. For best ripple performance, ESR should be ≤0.15 Ω; 10 µF is recommended if board space permits, per Figure 17 and Application Information section.
Is the ADP3607AR-REEL pin-compatible with other members of the ADP360x family?
No - the ADP3607AR-REEL is not pin-compatible with ADP3603/3604/3605 variants. While all share SO-8 packaging, pin functions differ: ADP3603/3604/3605 are inverters (–3 V output) with distinct CP+/CP– assignments and no VSENSE pin, whereas ADP3607AR-REEL is a 5 V doubler with dedicated VSENSE and NC pin placement as shown in the Pin Configuration diagram.
