Product details
Overview
AP7380-30WR-7 from Diodes Incorporated is a fixed 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 (WR) package. It delivers ±1% output voltage accuracy, 500mV dropout at 50mA, 1.8µA ground current at zero load, and operates across 3.5V–24V input range-enabling direct regulation from 12V/24V rails or multi-cell batteries in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7380-30WR-7 datasheet, AP7380-30WR-7 pinout, AP7380-30WR-7 application, or AP7380-30WR-7 equivalent, key selection criteria include dropout performance under 150mA load, thermal shutdown behavior at +160°C, compatibility with 1µF ceramic output capacitors, and EN pin logic thresholds (2.0V high / 0.4V low) for system-level power sequencing control.
Technical Context
The AP7380-30WR-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit protection (150mA), and enable-controlled shutdown. Its architecture supports stable operation with low-ESR ceramic capacitors and exhibits ±100ppm/°C output voltage drift over –40°C to +125°C junction temperature.
Line regulation is 0.05%/V and load regulation is 0.5% across 1–150mA output current, while thermal shutdown activates at +160°C with +20°C hysteresis-ensuring robust fault recovery in thermally constrained PCB layouts without external thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% - ensures stable MCU core or sensor biasing without external feedback components. |
| Max Input Voltage | 24V - allows direct connection to industrial 12V/24V supplies or 6-cell Li-ion battery stacks. |
| Dropout Voltage | 360mV typ @ 50mA - enables >90% efficiency at light loads when VIN = 3.36V, critical for battery runtime extension. |
| Ground Current | 1.8µA typ @ IOUT = 0mA - minimizes standby power loss in always-on monitoring circuits. |
| EN Pin Threshold | VIL = 0.4V, VIH = 2.0V - compatible with 1.8V/3.3V GPIOs for precise enable/disable control. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Output Accuracy | ±1% over temperature and line/load - eliminates need for post-regulation trimming in precision analog signal chains. |
Pinout & Package
SOT25 (WR) package: 5-pin surface-mount outline with exposed pad (non-electrical), 3.0mm × 2.8mm footprint, 1.1mm height, matte tin-plated leads, moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and thermal path to PCB copper; must be connected to solid ground plane for thermal performance. |
| 2 | VIN | Main input supply terminal; accepts 3.5–24V DC; requires 1µF ceramic input capacitor placed ≤2mm from pin. |
| 3 | VOUT | Regulated 3.0V output; drives load and 1µF ceramic output capacitor; sensitive to trace inductance. |
| 4 | NC | No internal connection; left unconnected or tied to GND for mechanical stability only. |
| 5 | EN | Active-high enable input; pulls regulator into <0.01µA standby mode when held ≤0.4V; requires clean digital logic drive. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 1.8µA at zero load - extends battery life in IoT sensors operating in deep-sleep cycles. |
| Low-ESR ceramic capacitor support | Stable with 1µF X5R/X7R output cap - eliminates bulk tantalum or electrolytic capacitors, reducing board area and cost. |
| High line/load regulation | 0.05%/V line, 0.5% load variation - maintains ADC reference stability despite input rail sag or dynamic load steps. |
| Integrated thermal shutdown | +160°C trip with +20°C hysteresis - enables automatic recovery after transient overloads without system reset. |
| Wide input range | 3.5V–24V operation - accommodates unregulated wall adapters, automotive transients, and multi-cell battery inputs without pre-regulation. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3002E/MB | 3.0V fixed, 250mA, 600mV dropout @ 250mA, 2.5µA IQ, SOT23-5 | Higher current capability but larger dropout at full load; no thermal shutdown | Select when >150mA peak load required and thermal fault protection is handled externally. |
| TPS7A2030PDBVR | 3.0V fixed, 300mA, 175mV dropout @ 300mA, 6.5µA IQ, WSON-6 | Lower dropout and higher current, but 3.5× higher quiescent current and no EN pin | Select for ultra-low-dropout priority in space-constrained designs where standby current is secondary. |

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP7380-30WR-7 requires VIN ≥ 3.5V to maintain regulation, as specified in Recommended Operating Conditions. Below this, output voltage collapses due to insufficient headroom for internal pass element operation-even though dropout voltage is as low as 360mV at 50mA.
Can the AP7380-30WR-7 be used with a 10µF aluminum electrolytic output capacitor?
No-datasheet specifies stability only with low-ESR ceramic capacitors (1µF typical). Aluminum electrolytics exhibit higher ESR and ESL, which can cause oscillation or poor transient response. Use X5R/X7R 1µF ceramics placed within 2mm of VOUT and GND pins.
Is the EN pin internally pulled up or down?
The EN pin has no internal pull-up or pull-down; it is a high-impedance CMOS input. External pull-up to VIN or microcontroller GPIO is required to ensure defined state during power-up. Leaving it floating may result in unpredictable regulator enable/disable behavior.
Does the AP7380-30WR-7 support reverse polarity protection?
No-the device lacks built-in reverse-voltage protection. Applying negative voltage to VIN or VOUT relative to GND exceeds Absolute Maximum Ratings and may cause permanent damage. An external series Schottky diode or dedicated protection IC is required for reverse-polarity environments.
