Product details
Overview
ADP3000AN-5 from Analog Devices is a micropower step-up/step-down switching regulator in 8-lead PDIP package, delivering fixed 5 V output with ±5% regulation (4.75–5.25 V), operating from 2 V to 30 V input, supporting up to 100 mA output in step-down mode and 100 mA in step-up mode, and used in portable instrumentation and cellular telephones.
For engineers reviewing the ADP3000AN-5 datasheet, ADP3000AN-5 pinout, ADP3000AN-5 application, or ADP3000AN-5 equivalent, this page provides verified technical context, confirmed pin functions, real-world operating modes (boost/buck), validated current-limit programming, and documented thermal behavior for space-constrained low-quiescent-current designs.
Technical Context
The ADP3000AN-5 uses pulse frequency modulation (PFM) with a 400 kHz oscillator and internal 1.245 V reference to regulate output via feedback comparator hysteresis. Its dual-collector/dual-emitter power switch enables configurable step-up (SW2 to GND, SW1 to inductor) or step-down (SW1 to VIN, SW2 to inductor) topologies without external MOSFETs.
It integrates a user-programmable current limit via ILIM pin (220 Ω resistor sets 400 mA limit), an auxiliary gain block (SET/AO pins) usable as low-battery detector or error amplifier, and operates at 500 µA shutdown quiescent current - enabling battery life extension in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.00 V ±5% (4.75–5.25 V); laser-trimmed on-die resistors eliminate external feedback network. |
| Input Voltage Range | 2.0 V to 12.6 V (step-up), 2.0 V to 30.0 V (step-down); supports single-cell Li-ion, multi-cell alkaline, and industrial supply rails. |
| Switching Frequency | 400 kHz typical (350–450 kHz); enables use of compact 6.8–15 µH inductors and low-ESR tantalum capacitors. |
| Quiescent Current | 500 µA in shutdown; critical for standby operation in pagers and palmtop computers. |
| Output Current Capability | 100 mA at 3 V from 5 V input (step-down), 100 mA at 5 V from 2–3.2 V input (step-up); verified per Figure 3 and Figure 28. |
| Current Limit Accuracy | 400 mA typical with 220 Ω ILIM-to-VIN resistor; temperature coefficient −0.3%/°C ensures stable overcurrent protection across 0°C–70°C. |
| Thermal Resistance | 120°C/W (N-8 PDIP package); junction temperature remains below 125°C at 70°C ambient with 185 mW dissipation. |
Pinout & Package
ADP3000AN-5 is housed in an 8-lead plastic DIP (N-8) package per JEDEC MO-095AA, with 0.300-inch width, 0.100-inch lead pitch, and through-hole mounting compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ILIM | Current limit programming input | Connect to VIN directly for max 1.5 A limit; use 220 Ω resistor to VIN for 400 mA limit - prevents inductor saturation and improves efficiency. |
| VIN | Main power input | Accepts 2–30 V; supplies internal bias and drives ILIM circuit; must be decoupled with ≥33 µF low-ESR capacitor. |
| SW1 | Power switch collector | In step-up: connects to inductor cathode; in step-down: connects to input rail - requires Schottky diode (e.g., 1N5817) for flyback path. |
| SW2 | Power switch emitter | In step-up: tied to GND; in step-down: drives inductor - must not go >0.5 V below GND to avoid damage. |
| FB (SENSE) | Feedback input | Internally connected to laser-trimmed divider for 5 V regulation; connect directly to output for closed-loop control. |
| GND | Analog and power ground | Single-point ground reference for comparator, reference, and driver; separate from high-current return paths to minimize noise. |
| SET | Auxiliary gain amplifier non-inverting input | Accepts resistor divider from VIN to configure low-battery detection; bias current 200–400 nA minimizes loading. |
| A0 | Auxiliary gain amplifier open-collector output | Sinks ≥300 µA; requires external pull-up for logic-level alert (e.g., MCU interrupt) or linear post-regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Step-up/step-down topology support | Single IC replaces discrete boost+buck solutions; eliminates need for external MOSFETs or controllers in dual-rail systems. |
| Programmable cycle-by-cycle current limit | Resistor-based ILIM interface allows precise inductor sizing and ripple control - reduces BOM count and PCB area. |
| Integrated 1.245 V precision reference | Enables ±5% output tolerance without external trimming; hysteresis stabilizes loop without compensation components. |
| Low-battery detection capability | On-chip gain block (SET/AO) delivers reliable undervoltage warning at <2.5 V input - avoids system brownout in Li-ion applications. |
| High-frequency PFM operation | 400 kHz switching minimizes inductor size (e.g., 6.8 µH Sumida CR43-6R8) and output capacitance (100 µF AVX TPS). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX630CPA+ | Fixed 5 V output, 2–16.5 V input, 125 mA output, 100 kHz switching, SO-8 package. | Limited to step-up only; lacks step-down capability and programmable current limit. | Choose when only boost operation is needed and lower switching frequency is acceptable for larger magnetics. |
| TPS61040DRVR | Adjustable 1.8–5.5 V output, 1.8–6 V input, 280 mA output, 600 kHz switching, 6-pin WSON package. | Requires external feedback resistors; no integrated gain block or low-battery detection. | Prefer for higher output current and smaller footprint where auxiliary monitoring functions are unnecessary. |
Compared with MAX630CPA+ and TPS61040DRVR, ADP3000AN-5 uniquely combines bidirectional topology, on-chip 5 V regulation, programmable current limiting, and integrated low-battery detection - making it optimal for space- and feature-constrained portable systems requiring both voltage boosting and bucking from a single IC.

FAQ
What is the maximum output current of the ADP3000AN-5 in step-down mode?
The ADP3000AN-5 delivers 100 mA at 3 V output from a 5 V input in step-down mode (per Figure 3 and datasheet Table 1). With optimized external components (e.g., 10 µH inductor, 1N5817 diode), it achieves 250 mA at 5 V output from 10–13 V input (Figure 32), though regulation tightness and thermal limits must be verified per application conditions.
Can the ADP3000AN-5 operate in inverting configuration to generate negative voltage?
Yes - the ADP3000AN-5 supports inverting (buck-boost) operation. Figure 33 shows a verified −5 V/100 mA inverter design using 5 V input, 15 µH inductor, and 1N5817 diode. The IC's dual-switch terminals (SW1/SW2) enable this topology without additional active components, though efficiency drops to ~60% due to diode conduction losses.
How is the 5 V output accuracy maintained across temperature and line variations?
The ADP3000AN-5 achieves ±5% output tolerance (4.75–5.25 V) via laser-trimmed internal resistive divider and a stable 1.245 V reference with 0.02–0.6%/V line regulation. Comparator hysteresis (32–50 mV) ensures loop stability without external compensation, and output voltage remains within spec across 0°C–70°C ambient per datasheet Table 1.
What package type does the ADP3000AN-5 use, and is it RoHS-compliant?
The ADP3000AN-5 uses an 8-lead plastic DIP (N-8) package per JEDEC MO-095AA, with through-hole mounting and 0.300-inch body width. While the original datasheet predates RoHS enforcement, Analog Devices confirms N-8 variants of the ADP3000 family meet RoHS Directive 2011/65/EU requirements with lead-free finish and compliant molding compounds.
Does the ADP3000AN-5 require external compensation components for stability?
No - the ADP3000AN-5 uses comparator hysteresis (8–12.5 mV) to ensure loop stability without external compensation. This eliminates the need for phase-compensation capacitors or resistors, reducing BOM count and simplifying design. Stability is verified across all operating modes (step-up, step-down, inverting) per Figures 27–33 and Theory of Operation section.
