Product details
Overview
AP7354D-30W5-7 from Diodes Incorporated is a 3.0V fixed-output, 150mA ultra-low quiescent current LDO regulator in SOT25 package with integrated enable control and active output discharge. It delivers ±1% output voltage accuracy over -40°C to +85°C, supports 2.0V–5.5V input range, and draws only 0.25µA quiescent current-enabling multi-year battery life in wearable sensors and IoT edge nodes.
For engineers reviewing the AP7354D-30W5-7 datasheet, AP7354D-30W5-7 pinout, AP7354D-30W5-7 application, or AP7354D-30W5-7 equivalent, key selection criteria include dropout voltage at 150mA (0.18V typ), EN logic thresholds (0.4V low / 1.0V high), active discharge resistance (35Ω), thermal resistance (162°C/W), and compatibility with 0.1µF ceramic input/output capacitors.
Technical Context
The AP7354D-30W5-7 integrates a precision voltage reference, error amplifier, current-limit circuit, and enable-controlled pass transistor. Its feedback loop maintains regulation under load transients up to 150mA while sustaining <40mV load regulation across 1–150mA for 3.0V output.
Unlike non-discharge variants, this part includes an internal NMOS discharge switch tied to the EN pin, activating automatically during shutdown to rapidly bleed VOUT to GND (35Ω typical path). The SOT25 package provides dedicated EN, VIN, VOUT, and GND terminals with no NC pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at +25°C; ±2% over full temperature range - ensures stable MCU core or sensor bias without external resistors. |
| Max Output Current | 150mA continuous - sufficient to power BLE SoCs, image sensors, or multi-sensor fusion modules. |
| Quiescent Current | 0.25µA typ - extends coin-cell battery life beyond 5 years in always-on wake-on-event applications. |
| Dropout Voltage | 0.18V typ at 150mA - enables operation down to 3.18V input, critical for single-cell Li-ion or alkaline systems near end-of-life. |
| EN Input Thresholds | VIL = 0.4V max, VIH = 1.0V min - compatible with 1.8V/3.3V GPIO without level-shifting. |
| Active Output Discharge | 35Ω typical resistance - discharges 3.0V output to <0.1V within ~1ms when EN goes low, preventing back-powering of upstream circuits. |
| Thermal Resistance θJA | 162°C/W (SOT25) - allows 150mA operation up to +85°C ambient with minimal derating on standard FR-4 PCB. |
Pinout & Package
SOT25 package: 5-pin surface-mount plastic package with exposed pad (not electrically connected); dimensions 2.80 × 2.90 × 1.30 mm; RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; accepts 2.0–5.5V; requires local 0.1µF ceramic decoupling to GND. |
| 2 | GND | Analog/digital ground reference; must connect directly to low-impedance PCB ground plane. |
| 3 | EN | Active-high enable; drives regulator ON when ≥1.0V, places it in shutdown (0.02µA standby) when ≤0.4V. |
| 4 | VOUT | Regulated 3.0V output; connects to load and 0.1µF ceramic capacitor; internally discharged when EN = low. |
| 5 | GND | Second ground terminal; ties to same net as Pin 2 to reduce ground loop impedance and improve PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 0.25µA typ enables >5-year runtime on CR2032 in periodic-sensing wearables. |
| Integrated Output Discharge | Eliminates need for external bleed resistor, reducing BOM count and board space in battery-backed systems. |
| High Accuracy Output | ±1% tolerance at +25°C ensures reliable brown-out detection margins for 3.0V microcontrollers. |
| Wide Input Range | 2.0–5.5V operation supports direct connection to USB, Li-ion, or multi-cell alkaline sources without pre-regulation. |
| Robust ESD Protection | 4kV HBM rating protects against handling damage during manual assembly and field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | No enable pin; 1.6µA IQ; 250mA output; SOT23-3 package. | Lacks EN control and output discharge; unsuitable for wake-on-event architectures. | Select only if system-level enable is handled externally and discharge is unnecessary. |
| Torex XC6210B302MR-G | 0.6µA IQ; no discharge; 150mA; SOT25; ±2% accuracy over temp. | Higher quiescent current reduces battery life by ~2.4× vs. AP7354D-30W5-7 in long-idle scenarios. | Prefer when cost sensitivity outweighs multi-year battery requirements. |
Compared with MCP1700T-3002E/TT and XC6210B302MR-G, the AP7354D-30W5-7 uniquely combines sub-µA quiescent current, integrated EN, and active discharge in a 5-pin SOT25-making it optimal for energy-harvested or infrequently serviced battery systems where autonomous shutdown behavior is mandatory.

FAQ
What is the minimum input voltage required for stable 3.0V output at 150mA?
The AP7354D-30W5-7 requires VIN ≥ 3.18V to maintain regulated 3.0V output at 150mA, based on its typical 0.18V dropout voltage. At lower inputs, output drops linearly; operation below 2.0V VIN is prohibited per absolute maximum ratings.
Can the EN pin be left unconnected if not used?
No-the EN pin must never float. If unused, tie EN directly to VIN to ensure permanent enable. Floating EN causes unpredictable regulator behavior due to noise susceptibility and violates the "must not be floating" requirement in the datasheet pin description.
Does the output discharge function operate when VIN is removed?
No-the active discharge circuit requires VIN to be present and EN pulled low. When VIN is absent, the internal discharge path is inactive; external bleeder resistors may be needed in zero-VIN fail-safe designs.
Is the SOT25 package thermally enhanced compared to SOT23?
Yes-SOT25 has θJA = 162°C/W versus SOT23's 170°C/W, and θJC = 38°C/W versus SOT23's 43°C/W. The larger pad area and dual GND pins improve heat dissipation, allowing higher sustained current at elevated ambient temperatures.
