Product details
Overview
AP7380-41Y-13 from Diodes Incorporated is a fixed-output 4.15V ultra-low dropout (ULDO) linear regulator IC designed for space-constrained, battery-powered systems. It delivers up to 150mA output current with 500mV dropout at 50mA, ±1% output voltage accuracy, and only 1.8µA ground current at full load-enabling long runtime in portable instrumentation and USB-powered devices.
For engineers reviewing the AP7380-41Y-13 datasheet, AP7380-41Y-13 pinout, AP7380-41Y-13 application, or AP7380-41Y-13 equivalent, key selection criteria include its 24V max input range, thermal shutdown at +160°C, SOT89-3 package footprint, and compatibility with low-ESR ceramic capacitors without external compensation.
Technical Context
The AP7380-41Y-13 integrates a precision voltage reference, error amplifier, resistor network for fixed 4.15V output, current-limit protection (150mA), and enable control logic. Its architecture supports stable regulation across -40°C to +125°C junction temperature with ±100ppm/°C output voltage drift.
It operates with input voltages from 3.5V to 24V, maintains 0.05%/V line regulation and 0.5% load regulation, and features thermal hysteresis of +20°C to prevent oscillation during overtemperature recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.15V ±1% - ensures stable supply for 4.2V Li-ion–biased analog sensors or MCU I/O rails. |
| Max Input Voltage | 24V - supports direct connection to industrial 24V bus or automotive battery systems with transient margin. |
| Dropout Voltage | 360–580mV @ 50mA - enables regulation down to VIN = 4.51V, critical for single-cell LiFePO₄ or multi-cell alkaline operation. |
| Ground Current | 1.8µA @ IOUT = 150mA - minimizes quiescent power loss in always-on monitoring circuits. |
| Thermal Shutdown | +160°C with +20°C hysteresis - provides robust fault recovery in enclosed enclosures without external thermal management. |
| ESD Rating | 2500V HBM - ensures reliability during PCB handling and end-equipment assembly. |
| Package | SOT89-3 (Option 2) - 4.6mm × 2.6mm footprint with exposed thermal pad; θJA = 118°C/W for passive heatsinking. |
Pinout & Package
SOT89-3 (Option 2) package: 4.6mm × 2.6mm × 1.6mm body with exposed thermal tab (Pin 2), optimized for thermal dissipation in high-ambient environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply terminal; accepts 3.5–24V DC; requires ≥1µF ceramic input capacitor for stability. |
| 2 | GND | Power ground and thermal reference; connected to exposed pad for optimal heat transfer to PCB copper. |
| 3 | VOUT | Regulated 4.15V output; requires ≥1µF low-ESR ceramic capacitor; no feedback resistors needed (fixed version). |
Key Features
| Feature | Design Value |
|---|---|
| Wide input range (up to 24V) | Eliminates need for pre-regulation stages in mixed-voltage systems such as industrial data loggers with 12/24V inputs. |
| Ultra-low quiescent current (1.8µA) | Extends battery life in wireless sensor nodes operating on coin cells or primary lithium batteries for >10-year deployments. |
| Ceramic capacitor compatible | Enables use of compact, high-reliability 0603/0805 MLCCs instead of bulkier tantalum or aluminum electrolytics. |
| Thermal shutdown with hysteresis | Prevents latch-up during sustained overload; automatic recovery after cooling avoids system reset dependency. |
| ±1% output accuracy | Meets tight tolerance requirements for ADC reference supplies and precision analog front-ends without trimming. |
Applications

| Industrial Data Loggers | Smart Home Sensor Hubs |
|
Use Scenario: Battery-backed environmental logger deployed in remote HVAC ducts (−25°C to +70°C ambient). IC Role / Device Role / Timing Role: Main regulator for microcontroller, EEPROM, and RS-485 transceiver from 3.6V LiSOCl₂ primary cell.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-4102E/MB | 4.1V output (0.05V lower), 250mV dropout @ 250mA, SOT23-5 package, no thermal shutdown. | Lacks overtemperature protection; unsuitable for sealed enclosures or high-ambient deployments. | Select only if thermal environment is controlled and 0.05V output offset is acceptable for downstream logic. |
| TPS7A2041PDBVR | 4.1V output, 130mV dropout @ 300mA, 6.5µA IQ, SOT23-5, integrated soft-start. | Higher quiescent current reduces battery life; smaller package limits thermal capacity for >100mA continuous loads. | Prefer for ultra-low-dropout needs below 100mA; avoid where ambient exceeds 60°C or sustained 150mA is required. |
Compared with MCP1703T-4102E/MB and TPS7A2041PDBVR, the AP7380-41Y-13 offers superior thermal robustness (160°C shutdown + hysteresis), lower ground current (1.8µA vs. 6.5µA), and higher input voltage capability (24V vs. 6V/13.2V), making it uniquely suited for industrial and wide-input portable designs.

FAQ
What is the minimum input voltage required for regulation at 4.15V output?
The AP7380-41Y-13 requires VIN ≥ VOUT + VDROP. At 50mA load, typical dropout is 360mV, so minimum VIN = 4.15V + 0.36V = 4.51V. The datasheet specifies absolute minimum operating VIN as 3.5V, but regulation is not guaranteed below VOUT + dropout voltage across temperature and process variation.
Can the AP7380-41Y-13 be used with tantalum output capacitors?
No-this device is explicitly characterized and optimized for low-ESR ceramic capacitors (≥1.0µF). Tantalum capacitors exhibit higher ESR and potential surge-current failure modes that may destabilize regulation or trigger current limit under load transients. Diodes recommends X5R/X7R MLCCs only.
Is the EN pin functional on the AP7380-41Y-13 fixed-output variant?
No-the AP7380-41Y-13 is a fixed-output version with no enable functionality. Pin 3 is VOUT; the EN terminal is unconnected (NC) in this configuration, as confirmed in the Pin Descriptions table (page 3 of DS39196 Rev. 4-2). Only adjustable versions include EN.
How does the SOT89-3 package affect thermal performance compared to SOT25?
The SOT89-3 package has θJA = 118°C/W (vs. 166°C/W for SOT25-WR), delivering ~40% better thermal resistance. Its exposed thermal tab enables direct PCB copper connection, allowing 150mA continuous output at +70°C ambient without forced airflow-whereas SOT25 variants require derating above 85°C.
