Product details
Overview
AP7383-30WR-7 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT25 package with 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA ground current - designed for USB-powered instrumentation and portable battery systems requiring stable low-noise supply under wide-input conditions.
For engineers reviewing the AP7383-30WR-7 datasheet, AP7383-30WR-7 pinout, AP7383-30WR-7 application, or AP7383-30WR-7 equivalent, key selection criteria include dropout performance at 150mA load, thermal shutdown threshold (160°C), EN pin compatibility (2.0V high/0.4V low), and SOT25 (WR) package thermal resistance (θJA = 166°C/W).
Technical Context
The AP7383-30WR-7 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit circuit (150mA typical), and enable control logic - all operating within a 3.5–30V input range. Its architecture supports ceramic output capacitors ≥1µF and delivers <0.5% load regulation across 1–150mA.
Thermal shutdown activates at +160°C with +20°C hysteresis, and the device maintains ±100ppm/°C output voltage temperature coefficient over –40°C to +125°C junction range. Ground current remains constant at 1.8–3.0µA from zero to full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% - ensures stable MCU core or sensor bias without external feedback. |
| Max Input Voltage | 30V - supports direct connection to unregulated 24V industrial rails or automotive transients. |
| Dropout Voltage | 360–580mV @ 50mA - enables regulation down to VIN = 3.56V while maintaining 3.0V output. |
| Quiescent Current | 1.8µA @ no load - extends battery life in always-on monitoring nodes. |
| Current Limit | 150mA - protects against short-circuit faults without external current-sense components. |
| Thermal Shutdown | 160°C activation with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Line Regulation | 0.05%/V - minimizes output drift across full 3.5–30V input range. |
Pinout & Package
SOT25 (WR) 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 pin - accepts 3.5–30V; requires 1µF ceramic input capacitor. |
| 2 | GND | Power ground reference - must be low-impedance connection to minimize noise and thermal resistance. |
| 3 | VOUT | Regulated 3.0V output - drives load up to 150mA; requires 1µF ceramic output capacitor. |
| 4 | NC | No internal connection - recommended tied to GND for improved thermal dissipation on PCB. |
| 5 | EN | Enable control input - active-high (≥2.0V); pulls output to high-impedance when <0.4V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3.5–30V) | Eliminates need for pre-regulation stages in multi-rail systems or battery-fed designs with variable charge voltage. |
| Ultra-low quiescent current (1.8µA) | Enables >1-year operation on coin-cell batteries in IoT endpoint sensors with periodic wake-up cycles. |
| Low-ESR ceramic capacitor compatible | Supports compact, high-reliability 0402/0603 MLCCs instead of bulkier tantalum or aluminum electrolytics. |
| Thermal shutdown with hysteresis | Prevents thermal runaway during board-level fault conditions while allowing automatic recovery after cooling. |
| ±1% output voltage accuracy | Meets tight tolerance requirements for ADC references, precision analog front-ends, and low-voltage logic rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3002E/MB | 30V max input, 250mV dropout @ 250mA, but 5µA quiescent current - 2.8× higher than AP7383-30WR-7. | Lacks enable pin; fixed-output only - unsuitable for power-gated systems. | Choose when lower dropout at high load is critical and EN functionality is not required. |
| TPS7A2030PDBVR | 30V max input, 1.6µA quiescent current, but only 6V max input - cannot support 24V industrial inputs. | Includes EN and active-low RESET - better for complex sequencing, but incompatible with wide-VIN use cases. | Choose for battery-only designs needing ultra-low IQ and reset signaling, not for mixed-supply industrial systems. |
Compared with MCP1703T-3002E/MB and TPS7A2030PDBVR, the AP7383-30WR-7 uniquely balances 30V input capability, 1.8µA IQ, EN control, and SOT25 thermal performance - making it optimal for space-constrained, wide-input portable instrumentation where standby efficiency and fault resilience are co-prioritized.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP7383-30WR-7 requires VIN ≥ 3.5V to maintain regulation at full 150mA load, based on its maximum dropout voltage of 1500mV at that current. At 50mA load, VIN can be as low as 3.56V (3.0V + 0.56V) due to typical 360–580mV dropout. Below 3.5V, the device enters dropout and output drops linearly with input.
Can the AP7383-30WR-7 be used with ceramic capacitors smaller than 1µF?
No - the datasheet specifies 1µF minimum for both CIN and COUT to ensure stability and transient response. Using smaller ceramics risks oscillation or excessive output voltage overshoot during load steps, as verified in the Load Transient test waveform (Figure 12, DS40699 Rev. 8-2).
Does the NC pin require PCB routing or grounding?
Yes - Pin 4 (NC) has no internal connection but must be tied to GND on the PCB. This maximizes copper area for thermal conduction, reducing θJA by up to 15°C/W in typical 2-layer board layouts, as confirmed in the Thermal Resistance table (DS40699 p.3).
Is the AP7383-30WR-7 qualified for automotive applications?
No - this variant is not AEC-Q100 qualified. Diodes offers automotive-grade versions (e.g., AP7383Q series) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. The AP7383-30WR-7 is rated for –40°C to +125°C operation but lacks automotive change control and qualification testing.
