Product details
Overview
AP7383-30Y-13 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator in SOT89 package, featuring 30V max input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA quiescent current - designed for USB-powered instrumentation and portable battery-operated systems requiring stable low-noise supply under wide input variation.
For engineers reviewing the AP7383-30Y-13 datasheet, AP7383-30Y-13 pinout, AP7383-30Y-13 application, or AP7383-30Y-13 equivalent, key selection criteria include dropout performance at 150mA load, thermal shutdown threshold (+160°C), EN pin compatibility with 2.0V logic-high, and SOT89 thermal resistance (118°C/W) for ambient-limited industrial deployments.
Technical Context
The AP7383-30Y-13 integrates a precision voltage reference, error amplifier, and resistor network to maintain 3.0V output across -40°C to +125°C junction temperature. Its current-limit circuit triggers at 150mA, and thermal shutdown activates at +160°C with +20°C hysteresis - enabling robust operation in unregulated 12–24V rail environments.
It supports ceramic output capacitors as low as 1.0µF with excellent line regulation (0.05%/V) and load regulation (±0.5%), while its enable input allows system-level power sequencing. The device operates down to 3.5V input, making it suitable for post-buck or battery-fed intermediate rails where headroom is constrained.
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 24V industrial or automotive auxiliary rails. |
| Dropout Voltage | 500mV @ 50mA - enables regulation from 3.5V input, critical for single-cell LiFePO₄ or dual-cell alkaline systems. |
| Quiescent Current | 1.8µA - extends battery life in always-on monitoring nodes with infrequent wake-up cycles. |
| Current Limit | 150mA - protects downstream circuitry during short-circuit or overload without external foldback. |
| Thermal Shutdown | +160°C with +20°C hysteresis - prevents latch-up during sustained high-power dissipation in enclosed enclosures. |
| Line Regulation | 0.05%/V - minimizes output drift across full 3.5–30V input range, reducing need for post-regulation filtering. |
Pinout & Package
SOT89 package (4.5mm × 2.5mm × 1.5mm), 3-pin thermally enhanced outline with exposed tab connected to GND for improved heat dissipation (θJA = 118°C/W on JEDEC High-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input Supply Terminal | Accepts 3.5–30V unregulated input; requires 1µF ceramic decoupling close to pin. |
| GND (Pin 2) | Ground Reference & Thermal Pad | Primary return path and thermal conduction node; PCB copper pour under tab mandatory for thermal performance. |
| VOUT (Pin 3) | Regulated Output Terminal | Delivers stable 3.0V ±1%; supports 1µF ceramic output capacitor for transient response and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range (3.5–30V) | Eliminates need for pre-regulation in 12/24V systems, reducing BOM count and board space. |
| Ultra-Low Quiescent Current (1.8µA) | Enables >10-year battery life in low-duty-cycle IoT sensors powered by CR2032 or AA cells. |
| Low ESR Ceramic Capacitor Compatible | Permits use of compact, high-reliability 0603/0805 MLCCs instead of bulkier tantalum or aluminum electrolytics. |
| Integrated Thermal Shutdown | Autonomous protection against PCB overheating due to poor airflow or excessive ambient temperature. |
| High Output Accuracy (±1%) | Meets tight tolerance requirements for ADC references, RF front-end biasing, and precision analog signal chains. |
Applications
| Portable Medical Sensors | Industrial Data Loggers |

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-3002E/MB | 250mV dropout @ 250mA, but only 16V max input; 2.5µA IQ | Lacks 30V input capability - unsuitable for 24V industrial or automotive battery-fed designs | Select only if input never exceeds 16V and lower dropout at higher load is prioritized |
| TPS7A2030PDBVR | 175mV dropout @ 300mA, 5.5V max input, 6.5µA IQ, no thermal shutdown | Not rated for >5.5V input - requires pre-regulation stage for 12V+ supplies | Prefer for low-dropout needs in 3.3V/5V systems where thermal protection is handled externally |
Compared with MCP1703T-3002E/MB and TPS7A2030PDBVR, the AP7383-30Y-13 uniquely combines 30V input tolerance, integrated thermal shutdown, and sub-2µA quiescent current - making it the only viable choice for direct 24V-to-3.0V conversion in thermally constrained, battery-sensitive, or transient-prone environments.

FAQ
What is the minimum input voltage required for regulation at full 150mA load?
The AP7383-30Y-13 requires VIN ≥ VOUT + VDROP. At 150mA, typical dropout is 1050mV (max 1500mV per datasheet), so minimum input is 3.0V + 1.05V = 4.05V. The recommended operating minimum is 3.5V, but full-load regulation begins at ~4.05V under typical conditions.
Does the AP7383-30Y-13 require an enable signal to operate?
No - the AP7383-30Y-13 has no enable pin in the SOT89 (Y) package. Pinout is VIN-GND-VOUT only. Enable functionality exists only in SOT25 W5 variant (Pin 4 = EN); this part is a fixed-output, always-on regulator unless input is removed.
Can the AP7383-30Y-13 be used with a 10µF aluminum electrolytic output capacitor?
Yes, but not optimal. The device is optimized for low-ESR ceramic capacitors (≥1µF). Aluminum electrolytics have higher ESR and may degrade transient response and stability margin. If used, ensure ESR ≤ 100mΩ and add a 100nF ceramic in parallel for high-frequency bypass.
Is the SOT89 package lead-free and RoHS-compliant?
Yes - the AP7383-30Y-13 uses matte tin-plated leads, is fully RoHS 3 compliant (2015/863/EU), halogen- and antimony-free ("Green"), and meets J-STD-020 Level 3 moisture sensitivity requirements for standard reflow assembly.
