Product details
Overview
AP7380-30W5-7 from Diodes Incorporated is a fixed 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 package, featuring 24V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA ground current at zero load-designed for USB-powered instrumentation and portable battery systems requiring stable low-noise supply under wide input variation.
For engineers reviewing the AP7380-30W5-7 datasheet, AP7380-30W5-7 pinout, AP7380-30W5-7 application, or AP7380-30W5-7 equivalent, key selection criteria include dropout performance at 150mA load, thermal shutdown threshold (+160°C), EN pin logic thresholds (2.0V high / 0.4V low), and compatibility with 1µF ceramic input/output capacitors in space-constrained SOT25 layouts.
Technical Context
The AP7380-30W5-7 implements a bandgap-referenced error amplifier driving a PMOS pass transistor, enabling low dropout operation without external compensation. Its enable circuit supports active-high logic control with sub-1µA standby current, and internal current limiting (150mA typ.) and thermal shutdown (160°C trip, 20°C hysteresis) provide robust fault protection.
Designed for fixed-output use, it omits external feedback resistors and integrates trimming for ±1% VOUT accuracy over -40°C to +125°C. Line regulation is 0.05%/V and load regulation is 0.5% across 1–150mA, ensuring stability in battery discharge scenarios where VIN drops from 24V to 3.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% - ensures precise biasing for 3.3V-tolerant microcontrollers and sensors without external resistor network |
| Max Input Voltage | 24V - supports direct connection to 12V/24V industrial or automotive battery rails with margin |
| Dropout Voltage | 360–580mV @ 50mA - enables regulation down to VIN = 3.36V, critical for Li-ion (3.0–4.2V) and multi-cell alkaline supplies |
| Ground Current | 1.8µA @ IOUT = 0mA - minimizes quiescent drain in always-on battery backup circuits |
| Current Limit | 150mA typical - protects downstream circuitry while sustaining peak loads of RF modules or display drivers |
| Thermal Shutdown | +160°C trip with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking |
| EN Pin Threshold | 2.0V min "high", 0.4V max "low" - compatible with 1.8V/3.3V GPIO without level-shifting |
Pinout & Package
SOT25 (W5) is a 5-pin, lead-free, RoHS-compliant surface-mount package with exposed thermal pad (pin 4/5 NC, not connected in fixed version). Thermal resistance θJA = 193°C/W enables 150mA operation up to +85°C ambient with minimal copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main power input; accepts 3.5–24V DC with internal ESD protection (2500V HBM) |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection to minimize noise coupling |
| 3 | VOUT | Regulated 3.0V output; requires ≥1µF ceramic capacitor within 5mm for stability |
| 4, 5 | NC | No connect - pins 4 and 5 are unconnected in fixed-output W5 variant; not to be tied to GND or VIN |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 1.8µA at zero load - extends shelf life and runtime in energy-harvesting or coin-cell applications |
| Wide input range support | 3.5V to 24V operation - eliminates need for pre-regulation stages in mixed-voltage systems |
| Ceramic capacitor compatibility | Stable with ≥1µF X5R/X7R MLCCs - reduces board area vs. tantalum and avoids ESR-related instability |
| High accuracy over temperature | ±100ppm/°C tempco - maintains <±2% total error from -40°C to +125°C junction |
| Integrated enable control | Active-high EN with 1µA input current - allows direct MCU GPIO control without pull-up resistors |
Applications
| USB-Powered Test Equipment | Portable Medical Sensors |
|---|---|
Use Scenario: Handheld multimeter powered via USB-C PD negotiation delivering 5–20V input. IC Role / Device Role / Timing Role: Primary 3.0V LDO supplying ADC reference, microcontroller core, and LCD driver from variable USB bus voltage. Use Value: 500mV dropout ensures regulation remains active even when USB source drops to 3.5V, preventing brownout resets during cable flex or connector wear. | Use Scenario: Wearable pulse oximeter using single-cell LiPo (3.0–4.2V) with Bluetooth LE transmission bursts. IC Role / Device Role / Timing Role: Low-noise 3.0V supply for analog front-end (AFE) and BLE SoC during 150mA TX peaks. Use Value: 150mA current limit and thermal shutdown protect against short-circuit faults during sensor probe contact, while 1.8µA quiescent current preserves battery charge between measurements. |
| Industrial Data Loggers | Smart Home Battery Gateways |
Use Scenario: Remote environmental logger powered by 24V solar-charged lead-acid battery with wide voltage swing (20–28V). IC Role / Device Role / Timing Role: Post-regulator stepping 24V down to clean 3.0V for real-time clock (RTC), EEPROM, and low-power MCU sleep mode. Use Value: 24V absolute max rating and 193°C/W θJA allow direct connection to battery rail without Zener clamp or buck pre-regulator, reducing BOM count and failure points. | Use Scenario: Zigbee-to-Matter bridge using 4xAA alkaline pack (4.0–6.4V) powering MCU, radio, and status LEDs. IC Role / Device Role / Timing Role: Always-on 3.0V rail enabling fast wake-from-sleep response (<10µs startup time) for motion-triggered automation. Use Value: Active-high EN pin synchronized to MCU GPIO permits instantaneous power gating, cutting system idle current to sub-µA levels without external MOSFET. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/MB | 250mA rated, 175mV dropout @ 250mA, but only 16V max input | Lacks 24V tolerance; unsuitable for industrial 24V rail or automotive load-dump scenarios | Select when higher output current and lower dropout are needed below 16V input, and PCB layout allows SOT23-3 |
| Torex XC6206P302MR-G | 150mA rated, 400mV dropout @ 100mA, 6V max input, no EN pin | No enable function; requires external FET for power sequencing; limited to low-voltage battery apps | Choose for cost-sensitive, low-input-voltage designs where EN control is unnecessary and footprint is constrained |
Compared with MCP1700T-3002E/MB and XC6206P302MR-G, the AP7380-30W5-7 uniquely combines 24V input capability, integrated EN, and SOT25 thermal performance-making it the only option among the three qualified for direct 24V industrial sensor node power without derating or external protection.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP7380-30W5-7 requires VIN ≥ 3.5V to maintain regulation, as specified in Recommended Operating Conditions. Below this, output voltage collapses linearly with input due to insufficient headroom for the PMOS pass element and internal reference circuitry.
Can pins 4 and 5 of the SOT25 package be left floating or must they be grounded?
Pins 4 and 5 are explicitly marked "NC" (No Connect) in the datasheet for the fixed-output AP7380-30W5-7. They must remain unconnected-neither grounded nor tied to any voltage-since internal bonding wires are absent and connection risks latch-up or parametric shift.
Does the AP7380-30W5-7 require an input capacitor, and if so, what value and type?
Yes: a minimum 1.0µF X5R or X7R ceramic capacitor is required at VIN, placed within 5mm of pins 1 and 2. This stabilizes the control loop and suppresses high-frequency noise from upstream sources like switching converters or noisy USB ports.
Is the AP7380-30W5-7 qualified for automotive applications per AEC-Q100?
No-the AP7380-30W5-7 is not AEC-Q100 qualified. Diodes states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; this part is intended for industrial and consumer portable applications only.
