Product details
Overview
AP7383-30WW-7 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 (WW) package. It operates across 3.5V–30V input range, delivers ±1% output voltage accuracy at 10mA load, features 360mV typical dropout at 50mA, and draws only 1.8µA ground current-enabling long battery life in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7383-30WW-7 datasheet, AP7383-30WW-7 pinout, AP7383-30WW-7 application, or AP7383-30WW-7 equivalent, key selection criteria include wide VIN tolerance, thermal shutdown behavior at +160°C, EN pin logic thresholds (2.0V high / 0.4V low), and compatibility with 1µF ceramic output capacitors without external compensation.
Technical Context
The AP7383-30WW-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit circuit (150mA trip), and enable control logic. Its architecture supports stable regulation under fast load transients while maintaining ultra-low quiescent current across temperature.
Thermal protection activates at +160°C junction temperature with +20°C hysteresis; line regulation is 0.05%/V and load regulation is 0.5% over 1–150mA. The device uses internal PMOS pass transistor topology, eliminating need for external bypass capacitor and enabling operation with low-ESR ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% at 10mA - ensures stable MCU core or sensor biasing without external feedback. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to 12V/24V industrial rails or multi-cell battery stacks. |
| Dropout Voltage | 360mV typ @ 50mA - enables 3.0V output from 3.36V input, critical for low-headroom battery systems. |
| Ground Current | 1.8µA typ @ IOUT = 0A - extends shelf life and runtime in always-on IoT sensors and metering devices. |
| Current Limit | 150mA min - provides robust short-circuit protection without latch-up, suitable for driving small displays or interface ICs. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| EN Pin Threshold | 2.0V (min "high"), 0.4V (max "low") - compatible with 3.3V/1.8V GPIOs for precise power sequencing control. |
Pinout & Package
SOT25 (WW) package: 5-pin surface-mount, 2.8mm × 2.9mm footprint, 1.05mm height, matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts up to 30V DC with internal overvoltage protection. |
| 2 | GND | Power ground reference; must be low-impedance connection to minimize noise and thermal resistance. |
| 3 | VOUT | Regulated 3.0V output; requires ≥1µF ceramic capacitor placed within 3mm for stability. |
| 4 | NC | No-connect terminal; internally unconnected, recommended tied to GND for improved thermal dissipation. |
| 5 | EN | Active-high enable input; pulls device into ultra-low standby mode (<0.01µA) when driven below 0.4V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range (3.5–30V) | Eliminates need for pre-regulation stages in automotive accessory or industrial 24V-powered designs. |
| Ultra-Low Quiescent Current (1.8µA) | Enables >10-year battery life in CO detectors or smart utility meters operating on CR2032 cells. |
| Ceramic Capacitor Compatible | Supports 1µF X5R/X7R output caps - reduces BOM cost and board area vs. tantalum or electrolytic alternatives. |
| Thermal Shutdown + Hysteresis | +160°C trip with +20°C recovery margin prevents cycling during transient overloads in enclosed enclosures. |
| ±1% Output Accuracy | Meets tight analog sensor biasing requirements (e.g., 3.0V reference for 12-bit ADCs) without calibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3002E/MB | 300mA rated, 600mV dropout @ 250mA, 2.5µA IQ, SOT23-5 package | Higher current capacity but larger dropout; lacks thermal hysteresis | Select when >150mA load or smaller footprint required; verify thermal performance under sustained 300mA. |
| TN8203-30 | 150mA rated, 400mV dropout @ 50mA, 2.0µA IQ, SOT25 package, AEC-Q100 Grade 2 qualified | Automotive-qualified with extended temp range (-40°C to +125°C), same pinout | Choose for automotive body electronics where PPAP compliance and IATF 16949 traceability are mandatory. |
Compared with MCP1703T-3002E/MB and TN8203-30, the AP7383-30WW-7 offers superior dropout (360mV vs. 400–600mV) and tighter output accuracy (±1% vs. ±2%), making it optimal for battery-constrained and precision analog applications-though TN8203-30 remains preferred where automotive qualification is required.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP7383-30WW-7 requires a minimum input voltage of 3.5V to maintain regulation at 3.0V output, as specified in Recommended Operating Conditions. Below this, the device enters dropout mode and VOUT drops linearly with VIN; the 360mV typical dropout at 50mA means regulation is sustained down to VIN = 3.36V under that load condition.
Can the NC pin (Pin 4) be left floating on the PCB?
No-Pin 4 is internally unconnected but must be tied to GND on the PCB. Diodes explicitly recommends this connection to maximize copper area for thermal dissipation, improving power handling capability and reducing junction temperature rise by up to 15°C under 150mA load in standard JEDEC layout.
Does the AP7383-30WW-7 require an input capacitor?
Yes-an input capacitor (CIN = 1.0µF ceramic) is required per the Typical Applications Circuit. It stabilizes the input rail during fast load transients and reduces high-frequency noise coupling from upstream sources; omission risks instability or increased output ripple, especially when powered from long traces or switching supplies.
Is the AP7383-30WW-7 qualified for automotive applications?
No-the AP7383-30WW-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., TN8203-30) with PPAP capability and IATF 16949 manufacturing, but the AP7383 series is intended for industrial, computing, and consumer applications. For automotive use, consult Diodes' automotive product line and request formal qualification documentation.
