Product details
Overview
ADP3000AR-5 from Analog Devices is a micropower step-up/step-down switching regulator in 8-lead SOIC (R-8) package, supporting fixed 5 V output with input range 2–30 V. It operates at 400 kHz, delivers up to 100 mA at 5 V from 5 V input in step-down mode, and features on-chip low-battery detection, user-adjustable current limit, and pulse-frequency modulation for 500 µA quiescent current. Used in portable instrumentation and cellular telephones.
For engineers reviewing the ADP3000AR-5 datasheet, ADP3000AR-5 pinout, ADP3000AR-5 application, or ADP3000AR-5 equivalent, key selection criteria include its dual-mode topology (boost/buck), 400 kHz switching frequency enabling compact magnetics, 500 µA shutdown quiescent current, integrated 1.245 V reference, and programmable current limit via ILIM pin - all critical for battery-powered space-constrained designs.
Technical Context
The ADP3000AR-5 implements a gated oscillator architecture operating in pulse-frequency modulation (PFM) mode, delivering regulated 5 V output using internal 1.245 V reference and comparator hysteresis (12.5 mV). Its dual external transistor terminals (SW1 collector, SW2 emitter) enable both step-up and step-down configurations without external power switches.
It integrates an auxiliary gain block (open-collector AO output, 300 µA sink capability) with SET pin for low-battery detection or error amplification, and supports cycle-by-cycle current limiting via resistor-connected ILIM pin - with 400 mA default limit when tied to VIN and scalable down using external resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.00 V ±5% (laser-trimmed internal divider; no external feedback resistors required) |
| Input Voltage Range | 2 V to 12 V (step-up), 2 V to 30 V (step-down); enables single IC across wide battery-input systems |
| Switching Frequency | 400 kHz typical (350–450 kHz range); permits use of small inductors (e.g., 6.8 µH) and low-ESR capacitors |
| Quiescent Current | 500 µA in shutdown (VFB > 1.43 V); enables multi-week battery life in standby instrumentation |
| Current Limit | 400 mA typical (with 220 Ω from ILIM to VIN); protects external magnetics and diodes during overload |
| Reference Voltage | 1.245 V ±4.5% (internal bandgap); sets regulation accuracy and hysteresis stability |
| Operating Temperature | 0°C to +70°C ambient; validated for industrial portable equipment environments |
Pinout & Package
ADP3000AR-5 is housed in an 8-lead SOIC (R-8) package per JEDEC MS-012AA, with 1.27 mm lead pitch, 4.90 mm × 3.90 mm body, and thermal resistance θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ILIM | Current limit programming input | Connect to VIN for 400 mA limit; add resistor to VIN to scale limit downward (e.g., 220 Ω → 400 mA) |
| VIN | Main power supply input | Accepts 2–30 V; powers internal circuitry and drives ILIM/SW1 in step-down mode |
| SW1 | Internal NPN transistor collector | In step-up: drives inductor; in step-down: connects to VIN rail - must withstand up to 50 V transient |
| SW2 | Internal NPN transistor emitter | In step-up: connected to GND; in step-down: drives inductor - must not go < −350 mV below GND |
| FB (SENSE) | Feedback input / voltage sense | Internally connected to laser-trimmed 5 V divider; connect directly to output for regulation |
| GND | Analog and power ground reference | Single ground pin; requires low-impedance PCB connection to minimize noise coupling into FB/SET |
| SET | Auxiliary amplifier non-inverting input | Accepts resistor divider from VIN for low-battery detection; bias current ≤330 nA at 25°C |
| AO | Auxiliary gain block open-collector output | Sinks ≥300 µA; used for low-battery flag or post-regulator control - requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Dual-mode topology | Single IC supports both step-up (2–12 VIN → 5 V) and step-down (2–30 VIN → 5 V), eliminating need for separate boost/buck solutions |
| Low-quiescent-current PFM control | 500 µA shutdown IQ enables >1-year shelf life in coin-cell–powered devices like pagers and handheld meters |
| Integrated current limit programming | Resistor-based ILIM interface allows precise switch-current setting (400 mA default) without external sense resistors or op amps |
| On-chip 1.245 V reference with hysteresis | 12.5 mV comparator hysteresis ensures stable regulation without external compensation components |
| Auxiliary gain block | Uncommitted AO/SET pair functions as low-battery detector (e.g., trip at 3.2 V), linear post-regulator, or UVLO - no extra IC required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX738AESA+ | Fixed 5 V output, 200 kHz switching, 300 µA IQ, SO-8 package; lacks dual-mode capability and AO/SET gain block | Only supports step-up mode; unsuitable for systems requiring step-down from >5 V inputs | Select only if input is strictly 1.8–4.0 V and step-down operation is unnecessary |
| TPS61040DRVR | Adjustable output (1.8–5.5 V), 500 kHz, 25 µA IQ, 6-pin SOT-23; no step-down support, no ILIM or AO pins | Optimized for ultra-low-IQ boost only; cannot replace ADP3000AR-5 in buck or dual-mode designs | Choose only for new ultra-low-power boost-only applications where footprint and IQ are primary constraints |
Compared with MAX738AESA+ and TPS61040DRVR, the ADP3000AR-5 uniquely combines fixed 5 V output, true step-up/step-down flexibility, integrated current limiting, and auxiliary gain functionality - making it irreplaceable in mixed-input-voltage portable systems requiring functional integration and long battery life.

FAQ
What is the exact output voltage tolerance of the ADP3000AR-5?
The ADP3000AR-5 provides a fixed 5.00 V output with guaranteed tolerance of ±5% (4.75 V to 5.25 V) over temperature (0°C to +70°C) and line conditions, as specified in Table 1 of the Rev. A datasheet. This tight tolerance is achieved via on-chip laser-trimmed resistor networks, eliminating the need for external feedback components and ensuring consistent regulation across production units.
Can the ADP3000AR-5 operate in step-down mode from a 12 V input to 5 V output?
Yes, the ADP3000AR-5 supports step-down operation from inputs up to 30 V. In step-down mode with 12 V input, it delivers 5 V at up to 100 mA with typical efficiency of 77%, as verified in Figure 32 of the datasheet. The SW1 pin connects to VIN and SW2 drives the inductor, while the internal 1.245 V reference and comparator maintain regulation via the FB pin.
How is current limiting configured on the ADP3000AR-5?
Current limiting on the ADP3000AR-5 is set via the ILIM pin: tying ILIM directly to VIN yields a typical 400 mA switch current limit. To reduce the limit, connect a resistor between ILIM and VIN - e.g., a 220 Ω resistor sets the limit to 400 mA, while higher values scale it down per the relationship shown in Figures 13–15. No external sense resistor is required.
Does the ADP3000AR-5 require external compensation components?
No, the ADP3000AR-5 does not require external compensation. Its comparator incorporates 12.5 mV hysteresis, which inherently stabilizes the control loop across input and load variations. This eliminates the need for external RC networks or type-II/III compensators - a key advantage confirmed in the Theory of Operation section (Page 9) and validated in all typical application circuits (Figures 27–34).
What package type is used for the ADP3000AR-5?
The ADP3000AR-5 is supplied in an 8-lead SOIC (R-8) package per JEDEC MS-012AA, with dimensions 4.90 mm × 3.90 mm × 1.75 mm and 1.27 mm lead pitch. Thermal resistance is θJA = 120°C/W, and the package is RoHS-compliant - as documented in the Outline Dimensions section (Page 15) and Ordering Guide (Page 16).
