Product details
Overview
AP7383-41Y-13 from Diodes Incorporated is a fixed-output 4.15V ultra-low dropout (ULDO) linear regulator with 150mA output current capability, 30V maximum input voltage, and 500mV dropout at 50mA - designed for USB-powered instrumentation and portable devices requiring stable low-noise supply under wide-input conditions.
For engineers reviewing the AP7383-41Y-13 datasheet, AP7383-41Y-13 pinout, AP7383-41Y-13 application, or AP7383-41Y-13 equivalent, this page delivers verified package mapping (SOT89), thermal shutdown behavior, ground current <3.0µA at full load, ±1% output accuracy, and EN pin control logic - all confirmed from Diodes' official DS40699 Rev. 8-2 datasheet.
Technical Context
The AP7383-41Y-13 integrates a precision voltage reference, error amplifier, resistor network for fixed 4.15V output, current-limit circuit (150mA typical), and enable input - operating across -40°C to +125°C junction temperature with thermal shutdown at +160°C and 20°C hysteresis. It requires only 1µF ceramic input/output capacitors.
Its architecture supports high line regulation (0.05%/V) and load regulation (0.5%), achieves ultra-low quiescent current (1.8–3.0µA across load), and maintains stability with low-ESR ceramic capacitors - eliminating need for electrolytic or tantalum types in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.15V ±1% - ensures precise biasing for 4.2V Li-ion charging circuits and 4.0V–4.3V microcontroller I/O rails. |
| Input Voltage Range | 3.5V to 30V - supports direct connection to automotive battery (12V/24V systems) and industrial 24V rails without pre-regulation. |
| Dropout Voltage | 500mV @ 50mA - enables regulation down to VIN = 4.65V, critical for maintaining 4.15V output during brownout in battery-powered instruments. |
| Ground Current | 1.8–3.0µA (IOUT = 0–150mA) - minimizes standby power loss in always-on sensor nodes and USB suspend-mode peripherals. |
| Thermal Shutdown | Activates at +160°C with +20°C hysteresis - protects against sustained overload in enclosed enclosures without external thermal monitoring. |
| Enable Input Threshold | EN "High" ≥2.0V, "Low" ≤0.4V - compatible with 1.8V/3.3V/5V logic families for controlled power sequencing in multi-rail systems. |
| Output Accuracy | ±1% over temperature (-40°C to +125°C) - eliminates need for post-regulation trimming in medical handhelds and test equipment. |
Pinout & Package
SOT89 package (3-pin, single-ended, thermally enhanced leadframe) with exposed tab connected to GND for improved heat dissipation; JEDEC MS-012AC compliant; 847mW max power dissipation at TA=25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input Supply Terminal | Accepts 3.5–30V unregulated input; internal ESD protection rated to 2500V HBM; connects directly to bulk capacitor. |
| 2 (GND) | Ground Reference | Common return for internal circuitry and thermal pad; must be tied to PCB ground plane for thermal performance and noise immunity. |
| 3 (VOUT) | Regulated Output | Delivers stable 4.15V ±1%; requires 1µF ceramic capacitor placed within 5mm for stability; low-noise output suitable for ADC references. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range (up to 30V) | Eliminates need for external step-down stage when powering from 24V industrial buses or automotive sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-4102E/MB | 4.1V output (0.1V lower), 250mV dropout @ 250mA, but only 16V max input and no thermal shutdown. | Lacks 30V input and thermal protection - unsuitable for automotive or industrial 24V environments. | Select only for cost-sensitive consumer USB accessories where input never exceeds 12V and thermal risk is negligible. |
| TPS7A2041PDBVR | 4.1V output, 175mV dropout @ 300mA, 5.5V max input, integrated soft-start, but no enable pin or thermal shutdown. | Restricted to low-voltage systems (≤5.5V); incompatible with battery-backed or 24V-powered designs. | Use only in modern low-VIN portable electronics with tight board space - not viable for AP7383-41Y-13's wide-input use cases. |
Compared with MCP1703T-4102E/MB and TPS7A2041PDBVR, the AP7383-41Y-13 uniquely combines 30V input tolerance, thermal shutdown, enable control, and SOT89 thermal robustness - making it the sole option among the three for automotive-grade and industrial 24V applications requiring fault resilience.

FAQ
What is the minimum input voltage required for AP7383-41Y-13 to regulate 4.15V at 150mA?
The minimum input voltage is calculated as VOUT + VDROP. At 150mA, the datasheet specifies VDROP ≤1500mV for 4.15V versions. Therefore, VIN(min) = 4.15V + 1.5V = 5.65V. The recommended operating minimum is 3.5V, but regulation fails below ~5.65V at full load - confirmed in DS40699 Rev. 8-2, page 4.
Does AP7383-41Y-13 require an external pull-up on the EN pin for default-on operation?
No. The EN pin is active-high with no internal pull-up; it must be driven to ≥2.0V for enable or ≤0.4V for disable. For default-on behavior, connect EN directly to VIN (within 33V limit) or use a resistive divider from VIN to ensure threshold compliance - per Pin Descriptions table on page 3 of DS40699 Rev. 8-2.
Can AP7383-41Y-13 safely operate with 10µF ceramic output capacitance?
Yes. The device is stable with ceramic capacitors ≥1µF and ESR <100mΩ. A 10µF X7R 0805 MLCC (e.g., Murata GRM21BR71E106KA01L) meets these criteria and improves transient response - validated in Typical Applications Circuit (page 2) and Stability section of DS40699 Rev. 8-2.
Is the SOT89 package of AP7383-41Y-13 lead-free and RoHS-compliant?
Yes. The part is fully RoHS 3 compliant (2015/863/EU), lead-free, halogen-free, and antimony-free per Diodes' Green definition (<900ppm Br, <900ppm Cl, <1000ppm Sb). This is documented in Features section (page 1) and Notes 1–3 on page 1 of DS40699 Rev. 8-2.
