Product details
Overview
ADP1109AAN-5 from Analog Devices is a micropower step-up DC-to-DC converter in 8-lead plastic DIP package, delivering 100 mA at 5 V from a 3 V input, featuring 120 kHz fixed-frequency operation, logic-controlled shutdown, and 460 µA quiescent current in shutdown mode - used in battery-powered portable instruments and flash memory VPP generation.
For engineers reviewing the ADP1109AAN-5 datasheet, ADP1109AAN-5 pinout, ADP1109AAN-5 application, or ADP1109AAN-5 equivalent, this page provides verified technical context, real-world design meaning of specifications, validated pin functions, confirmed alternative options, and supply support for industrial embedded and portable electronics design.
Technical Context
The ADP1109AAN-5 integrates an internal 1.25 V reference, comparator with 12 mV hysteresis, and a gated 120 kHz oscillator to regulate output without external frequency compensation. Its internal NPN power switch has 0.4–0.8 V saturation voltage at 500 mA and supports duty cycles from 57% to 77% under full load.
Feedback is implemented via the SENSE (FB) pin, internally connected to laser-trimmed resistors for fixed 5 V output; no external resistor network is required. Shutdown is asserted by applying logic low (<0.8 V) to the SHUTDOWN pin, reducing operating current to 460 µA while retaining regulation readiness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.00 V ±2.5%, tightly regulated for powering logic rails and flash memory programming voltage (VPP) |
| Oscillator Frequency | 120 kHz typical, enables use of compact surface-mount inductors (e.g., 10–33 µH) without EMI filtering overhead |
| Quiescent Current | 460 µA in shutdown, critical for extending battery life in pagers and handheld inventory computers |
| Input Voltage Range | 2 V to 9 V, supports single-cell Li-ion (3 V), alkaline (2 V), and logic-supply (5 V) inputs |
| Switch Saturation Voltage | 0.4–0.8 V at 500 mA, directly limits conduction loss and thermal rise in boost stage |
| Output Ripple | 25–50 mV peak-to-peak, compatible with tantalum or low-ESR aluminum capacitors (e.g., 22 µF/10 V) |
| Shutdown Threshold | VIL = 0.8 V max, ensures reliable disable with standard CMOS/LVTTL logic outputs |
Pinout & Package
ADP1109AAN-5 is housed in an 8-lead plastic DIP (N-8) package with 0.300-inch width, through-hole mounting, and industry-standard lead pitch (0.100 inch). Pin 1 is marked by a notch or dot; pins 2 and 6 are no-connect (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VIN | Input supply connection | Accepts 2–9 V unregulated source; must be decoupled with ≥1 µF ceramic capacitor near pin |
| 2 NC | No connection | Not bonded; must remain unconnected on PCB to avoid parasitic coupling |
| 3 SW | Collector of internal NPN switch | Drives external inductor; voltage swings up to 50 V - requires Schottky catch diode (e.g., MBRS130T3) |
| 4 PGND | Power ground return | Low-impedance path for switch current; separate from signal GND to minimize noise injection |
| 5 GND | Signal ground reference | Reference for comparator, reference, and shutdown logic; tie to PGND at single point near device |
| 6 NC | No connection | Not bonded; leave floating - no trace or pad required |
| 7 SHUTDOWN | Logic enable/disable control | Active-low input; <0.8 V disables oscillator, >2.0 V enables; draws ≤20 µA when low |
| 8 FB(SENSE) | Feedback input / output voltage sense | Internally tied to fixed 5 V divider; connect directly to regulated 5 V output for closed-loop control |
Key Features
| Feature | Design Value |
|---|---|
| Micropower shutdown mode | 460 µA quiescent current preserves battery capacity during idle periods in portable instrumentation |
| Fixed 5 V output with internal trimming | Eliminates external feedback resistors - reduces BOM count and layout area in space-constrained designs |
| Gated oscillator architecture | Enables stable regulation without external compensation components, simplifying design validation |
| 120 kHz switching frequency | Optimizes inductor size vs. efficiency trade-off: 10–33 µH inductors achieve >80% efficiency at 100 mA |
| Logic-compatible shutdown interface | Direct interfacing with microcontroller GPIO or system power manager without level-shifting circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADP1109AAR-5 | Same electrical specs and internal trim; SO-8 surface-mount package instead of DIP | Required for automated SMT assembly; unsuitable for hand-soldered prototypes or through-hole boards | Select ADP1109AAR-5 when board space is constrained and reflow capability exists. |
| MAX630ESA+ | 5 V fixed output, 125 kHz oscillator, but higher 650 µA shutdown current and no internal feedback divider | Requires external R1/R2 for feedback; less suitable for lowest-BOM-count designs | Choose MAX630ESA+ only if SO-8 footprint compatibility and marginally higher efficiency at light loads are prioritized. |
Compared with ADP1109AAN-5, ADP1109AAR-5 offers identical performance in a smaller SO-8 package but sacrifices through-hole serviceability, while MAX630ESA+ demands external feedback and draws more shutdown current - making ADP1109AAN-5 optimal for cost-sensitive, low-component-count, and field-serviceable portable designs.

FAQ
What is the maximum output current capability of the ADP1109AAN-5?
The ADP1109AAN-5 can deliver up to 100 mA at 5 V when supplied from a 3 V input, as specified in the General Description and confirmed in Figure 3 of the datasheet. Output current is limited by internal switch saturation voltage, inductor selection, and thermal dissipation - exceeding 100 mA risks instability or thermal shutdown in the 8-lead DIP package.
Does the ADP1109AAN-5 require external feedback resistors to set its 5 V output?
No, the ADP1109AAN-5 does not require external feedback resistors. It uses laser-trimmed internal resistors to fix the output at 5.00 V; the SENSE (FB) pin is internally connected to this divider, so users simply tie it directly to the regulated output node - reducing BOM count and layout complexity versus adjustable versions like ADP1109AAN.
What is the recommended inductor value for the ADP1109AAN-5 in a 3 V to 5 V conversion?
For 3 V to 5 V conversion at 100 mA, the datasheet recommends a 10 µH inductor (e.g., Coiltronics CTX10-1 or Sumida CD54-100LC) with ≥300 mA saturation current and <0.4 Ω DC resistance. This value balances efficiency, size, and ripple - achieving ~85% efficiency while keeping peak switch current below 1.2 A.
Can the ADP1109AAN-5 operate from a 2 V input source?
Yes, the ADP1109AAN-5 operates from 2 V to 9 V input, as stated in the Features and Specifications tables. At 2 V input, it delivers reduced output current (e.g., ~110 mA at 5 V per Figure 3), but maintains regulation accuracy and stability - making it suitable for deeply discharged alkaline or NiMH cells.
Is the ADP1109AAN-5 pin-compatible with other variants in the ADP1109A family?
Yes, all ADP1109A variants - including ADP1109AAN-3.3, ADP1109AAN-5, ADP1109AAN-12, and ADP1109AAN (adjustable) - share identical 8-lead DIP pinouts and package dimensions. Only the internal feedback network differs; SENSE pin connection and external component values scale accordingly for each output voltage.
