Product details
Overview
AP7380-30Y-13 from Diodes Incorporated is a fixed-output 3.0V, 150mA ultra-low dropout (ULDO) linear regulator with 24V maximum input voltage, 500mV dropout at 50mA, ±1% output accuracy, and 1.8µA ground current at zero load-designed for battery-powered instrumentation and portable USB devices requiring stable low-noise supply under wide input variation.
For engineers reviewing the AP7380-30Y-13 datasheet, AP7380-30Y-13 pinout, AP7380-30Y-13 application, or AP7380-30Y-13 equivalent, this part delivers verified thermal shutdown, load/line regulation <0.5%/0.05%/V, compatibility with 1µF ceramic capacitors, and SOT89 package suitability for space-constrained industrial and portable designs.
Technical Context
The AP7380-30Y-13 integrates a precision voltage reference, error amplifier, resistor network for fixed 3.0V output, current-limit protection (150mA), and enable-controlled shutdown. Its architecture supports operation from 3.5V to 24V input while maintaining regulation down to VIN = VOUT + 360mV at 50mA load.
Thermal shutdown activates at +160°C with +20°C hysteresis; EN pin logic thresholds are 2.0V (high) and 0.4V (low); standby current is 0.01µA. It uses no external feedback components and requires only 1µF input/output ceramic capacitors for stability.
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 resistors. |
| Max Input Voltage | 24V - enables direct connection to 12V/24V industrial rails or multi-cell Li-ion batteries without pre-regulation. |
| Dropout Voltage | 360mV @ 50mA - sustains regulation even when input drops to 3.36V, critical for battery discharge end-of-life operation. |
| Ground Current | 1.8µA @ IOUT = 0 - minimizes quiescent power loss in always-on monitoring circuits and IoT edge nodes. |
| Line Regulation | 0.05%/V - maintains output stability across wide input swings, reducing need for additional filtering in noisy environments. |
| Load Regulation | 0.5% @ 1–150mA - guarantees consistent voltage delivery from sleep-mode µA loads to active 150mA peripherals. |
| Thermal Shutdown | +160°C activation with +20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking in SOT89 package. |
Pinout & Package
SOT89 (Option 2) package: 3-pin, single-sided leadframe thermally enhanced plastic outline with exposed tab (pin 2) for PCB heat dissipation; footprint dimensions per Diodes spec: 4.60×2.90mm body, 1.50mm lead pitch, 0.55mm pad width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main unregulated input supply connection; accepts 3.5–24V; decoupled with 1µF ceramic capacitor. |
| 2 | GND | Power ground reference and thermal path; connected to large copper pour for θJA = 118°C/W performance. |
| 3 | VOUT | Stable 3.0V regulated output; drives load up to 150mA; requires 1µF ceramic output capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (3.5–24V) | Eliminates need for intermediate buck stages in mixed-voltage systems, simplifying BOM for industrial handhelds. |
| Ultra-low quiescent current (1.8µA) | Extends battery life in always-on sensor nodes by >10× versus standard LDOs with ~50µA IQ. |
| Ceramic capacitor compatible (1µF min) | Reduces board area and cost vs. tantalum/electrolytic; avoids aging and ESR drift issues in long-life deployments. |
| Thermal shutdown with hysteresis | Enables safe recovery after fault without manual reset; +20°C hysteresis prevents oscillation near trip point. |
| ±1% output accuracy over temp | Meets tight analog front-end requirements for ADC references and precision op-amp supplies without calibration. |

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 |
|---|---|---|---|
| MCP1703T-3002E/MB | 3.0V fixed, 250mA, 600mV dropout @ 250mA, 2.5µA IQ, SOT23-5 package | Higher current but larger dropout; requires 5-pin layout and separate EN control | Select when >150mA load or independent enable sequencing is required; not drop-in due to pin count and thermal profile. |
| Torex XC6210B302MR-G | 3.0V fixed, 150mA, 250mV dropout @ 100mA, 1.0µA IQ, SOT25 package | Lower dropout and IQ, but rated only to 6V input; no thermal shutdown | Prefer for low-input, ultra-low-power applications where 24V tolerance and fault protection are unnecessary. |
Compared with MCP1703T-3002E/MB and XC6210B302MR-G, the AP7380-30Y-13 uniquely balances 24V input capability, integrated thermal protection, and SOT89 thermal performance-making it optimal for industrial portable gear where input voltage variability and reliability outweigh minimal IQ savings.

FAQ
What is the minimum input voltage required for regulation at full 150mA load?
The AP7380-30Y-13 requires VIN ≥ VOUT + VDROP. At 150mA and 3.0V output, typical dropout is 1050mV (max 1500mV). Thus, minimum input is 4.05V (typical) or 4.5V (worst-case), confirmed in Electrical Characteristics Table on page 4 of DS39196 Rev. 4-2.
Does the AP7380-30Y-13 require an external enable circuit?
No-the AP7380-30Y-13 is the fixed-output version without an enable pin; pin 3 is VOUT, pin 2 is GND, and pin 1 is VIN. The enable function exists only in adjustable versions (e.g., AP7381), and SOT89 (Option 2) packaging for AP7380 omits EN entirely per Pin Descriptions table on page 3.
Can 10µF aluminum electrolytic capacitors be used instead of 1µF ceramic?
No-datasheet specifies "compatible with low ESR ceramic capacitor" and characterizes stability only with 1.0µF X5R/X7R ceramics. Aluminum electrolytics exhibit higher ESR and capacitance drift, risking instability or startup failure; ceramic remains mandatory per Typical Applications Circuit and Performance Characteristics section.
Is the SOT89 package of AP7380-30Y-13 RoHS and halogen-free compliant?
Yes-per Features section and Notes 1–3 on page 2, AP7380-30Y-13 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen/antimony-free ("Green"), with Br+Cl <1500ppm and Sb <1000ppm, verified in Diodes' quality documentation referenced in the datasheet.
