Product details
Overview
AP2205-30Y-13 from Diodes Incorporated is a fixed-output 3.0V, 200mA ultra-low dropout (ULDO) linear regulator in SOT89 package, fabricated using high-voltage EPNP process. It delivers ±2% output voltage accuracy, 60dB PSRR at 1kHz, 100mV dropout at 100µA load, and ultra-low 36µA ground current at light load-enabling stable power for USB peripherals and portable instrumentation requiring low-noise, wide-input (2.3–24V) regulation.
For engineers reviewing the AP2205-30Y-13 datasheet, AP2205-30Y-13 pinout, AP2205-30Y-13 application, or AP2205-30Y-13 equivalent, key selection criteria include its 3.0V fixed output, thermal shutdown and reverse-current protection, compatibility with low-ESR ceramic capacitors, and suitability for battery-powered systems where quiescent current and dropout performance are critical.
Technical Context
The AP2205-30Y-13 integrates a precision 1.24V bandgap reference, error amplifier, resistor network for fixed 3.0V output, enable-controlled low-power shutdown mode, overcurrent and overtemperature protection, and reverse-current blocking. Its architecture supports operation across –40°C to +125°C junction temperature with no external compensation required.
It features active current limiting (250mA absolute max), thermal shutdown activation at ~150°C, and EN pin logic thresholds of 2.0V (high) and 0.4V (low), enabling clean system-level power sequencing. The device maintains <±0.5% load regulation up to 200mA and <±0.05% line regulation across its full 2.3–24V input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures stable rail for 3.3V-tolerant microcontrollers and sensors without external feedback resistors. |
| Max Output Current | 200mA @ VOUT ≥ 1.8V - sufficient for powering single-core MCUs, RF modules, or sensor interfaces in portable designs. |
| Dropout Voltage | 100mV @ IOUT = 100µA; 320mV @ IOUT = 100mA - enables regulation from 3.1V input at full load, extending battery runtime in 3.3V/3.0V systems. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC-DC converters, critical for analog signal chains and ADC references. |
| Ground Current | 36µA @ IOUT = 100µA; 1.3mA @ IOUT = 100mA - minimizes standby power loss in always-on IoT nodes and battery-backed real-time clocks. |
| Input Voltage Range | 2.3V to 24V - accommodates single-cell Li-ion (2.7–4.2V), 5V USB, 12V industrial rails, and automotive transients without external pre-regulation. |
| Thermal Shutdown | Activates at TJ ≈ 150°C - protects against sustained overload or poor PCB heatsinking in enclosed enclosures. |
Pinout & Package
SOT89 package: 3-pin, surface-mount, thermally enhanced plastic case with exposed pad (recommended GND connection). Pin 1 = VIN, Pin 2 = GND, Pin 3 = VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input supply terminal | Accepts 2.3–24V unregulated input; requires 1.0µF ceramic capacitor placed ≤2mm from pin for stability. |
| 2 (GND) | Power and reference ground | Common return for input/output capacitors and IC internal circuitry; must be connected to low-impedance PCB ground plane. |
| 3 (VOUT) | Regulated output terminal | Delivers fixed 3.0V ±2%; requires 2.2µF ceramic output capacitor with ESR <100mΩ for transient response and PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input voltage range | 2.3V to 24V - eliminates need for pre-regulators in multi-rail or legacy industrial systems. |
| Ultra-low quiescent current | 36µA at 100µA load - extends shelf life and operational time in coin-cell or energy-harvesting applications. |
| Reverse current protection | Blocks backflow from VOUT to VIN when input is removed - prevents unintended discharge of backup batteries or cross-rail coupling. |
| Low-noise output | 30µVRMS (10Hz–100kHz) - suitable for powering precision analog front-ends, PLLs, and RF synthesizers without additional filtering. |
| Enable control with low leakage | ISTD = 0.01–1.0µA in shutdown - allows deep-sleep modes in battery-powered devices while maintaining fast wake-up (<100µs). |
Applications
| USB-C Peripheral Power | Industrial Sensor Node |
|---|---|
Use Scenario: Powering USB-C audio adapters, HID dongles, or smart cables with variable input (5V–20V PD profiles). IC Role / Device Role / Timing Role: Primary 3.0V LDO delivering clean, regulated rail to USB PHY and MCU; handles input ripple from PD negotiation bursts. Use Value: 60dB PSRR rejects high-frequency PD switching noise; 24V max input withstands 20V PD fault conditions without derating. |
Use Scenario: Remote environmental monitoring node powered by 12V industrial bus or solar-charged LiFePO₄ battery. IC Role / Device Role / Timing Role: Main 3.0V supply for low-power MCU, analog sensor interface, and LoRaWAN transceiver during active and sleep cycles. Use Value: 36µA quiescent current enables >5-year battery life; thermal shutdown prevents failure in sealed outdoor enclosures. |
| Portable Medical Instrument | Automotive Infotainment Accessory |
Use Scenario: Handheld pulse oximeter or glucose meter operating from single-cell Li-ion (2.7–4.2V) with strict EMI limits. IC Role / Device Role / Timing Role: Low-noise 3.0V source for optical sensor ADC and display driver, replacing noisy switching regulators. Use Value: 30µVRMS noise avoids digitization artifacts; reverse-current protection isolates battery during USB charging. |
Use Scenario: Aftermarket OBD-II adapter drawing power from vehicle's 12V battery with cold-crank (6V) and load-dump (36V) transients. IC Role / Device Role / Timing Role: Post-regulator supplying 3.0V to Bluetooth SoC and CAN transceiver after primary 5V buck converter. Use Value: 24V absolute max input survives 20V load-dump clamping; ±2% accuracy ensures reliable CAN timing under voltage sag. |
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 | 3.0V fixed, 250mA, 6µA IQ, but only 16V max input and no reverse-current protection. | Lacks robustness for 24V industrial or automotive inputs; better suited for low-voltage embedded systems. | Select when ultra-low IQ dominates over input range and reverse-current blocking. |
| TLS850F3BVT | 3.3V fixed, AEC-Q100 qualified, integrated watchdog, but 350mV dropout at 200mA and higher 50µA IQ. | Designed for automotive body electronics; not drop-in due to voltage mismatch and qualification overhead. | Select only for AEC-Q100-compliant automotive designs requiring functional safety features. |
Compared with MCP1703T-3002E/MB and TLS850F3BVT, the AP2205-30Y-13 uniquely balances 24V input tolerance, reverse-current blocking, and sub-40µA light-load IQ-making it optimal for cost-sensitive, non-automotive portable and industrial applications needing 3.0V precision without qualification overhead.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP2205-30Y-13 requires VIN ≥ 3.1V to maintain regulation at full 200mA load (320mV dropout), but sustains regulation down to VIN = 3.0V + 100mV = 3.1V even at light loads. Below 3.1V, output drops linearly per dropout curve; datasheet specifies 2.3V absolute minimum for functionality, not regulation.
Can the AP2205-30Y-13 be used with ceramic output capacitors?
Yes-it is explicitly designed for low-ESR ceramic capacitors: 2.2µF X5R/X7R recommended at VOUT, with ESR <100mΩ. Unlike older LDOs, it does not require series resistance or tantalum capacitors for stability, simplifying layout and reducing BOM count.
Does the SOT89 package require thermal pad connection to PCB ground?
The SOT89 substrate/exposed pad should be connected to GND for optimal thermal performance (θJA = 129°C/W), though it may be left floating per datasheet Note 4. Grounding reduces junction temperature rise by ~25°C at 200mA, critical for reliability in enclosed or high-ambient environments.
Is the AP2205-30Y-13 qualified for automotive applications?
No-the AP2205-30Y-13 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP2205-30YQ-13) with PPAP capability and IATF 16949 manufacturing, but this part is intended for commercial/industrial use. Its 125°C max operating junction temperature supports extended-temperature industrial designs.
