Product details
Overview
AP2204K-3.0TRG1 from Diodes Incorporated is a fixed-output 3.0V ultra-low dropout (ULDO) linear regulator in SOT-23-5 package, designed for space-constrained portable electronics. It delivers up to 150mA output current with 100mV dropout at 100µA load, 60dB PSRR at 1kHz, ±2% output voltage accuracy, and ultra-low 20µA ground current at zero load - enabling stable power for USB peripherals and battery-powered microcontrollers.
For engineers reviewing the AP2204K-3.0TRG1 datasheet, AP2204K-3.0TRG1 pinout, AP2204K-3.0TRG1 application, or AP2204K-3.0TRG1 equivalent, key selection criteria include input voltage range (2.6–24V), thermal performance in SOT-23-5 (θJA = 250°C/W), enable control logic thresholds (EN high ≥2.0V, low ≤0.4V), and compatibility with low-ESR ceramic capacitors (1.0µF input / 2.2µF output).
Technical Context
The AP2204K-3.0TRG1 integrates a precision 1.24V bandgap reference, error amplifier, resistor network for fixed 3.0V output, current-limit protection, thermal shutdown, and an active-high enable circuit. Its EPNP process enables wide VIN operation while maintaining low quiescent current across temperature.
It operates in dropout when VIN < VOUT + 1V (i.e., VIN < 4.0V), with line regulation of 0.05% and load regulation of 0.5% over 1mA–150mA. The EN pin supports system-level power sequencing, and the GND pin serves as both reference and thermal path via the exposed pad connection in SOT-23-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures stable MCU core or sensor bias without external feedback components. |
| Input Voltage Range | 2.6V to 24V - supports single-cell Li-ion (3.0–4.2V), multi-cell alkaline, or industrial 12/24V rails. |
| Max Output Current | 150mA - sufficient for low-power microcontrollers, BLE modules, and analog sensors. |
| Dropout Voltage | 100mV @ 100µA - enables regulation down to VIN = 3.1V, critical for battery end-of-life operation. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO. |
| Ground Current | 20µA @ IOUT = 0A - minimizes standby power loss in always-on IoT endpoints. |
| Enable Threshold | EN high ≥2.0V, low ≤0.4V - compatible with 1.8V/3.3V GPIOs for precise power gating. |
Pinout & Package
SOT-23-5 package (3.0mm × 1.7mm × 1.3mm) with exposed thermal pad connected to GND for enhanced heat dissipation (θJC = 43°C/W). Pin 1 is VIN; Pin 2 is GND; Pin 3 is EN; Pin 4 is VOUT; Pin 5 is ADJ/NC (not connected internally for fixed version; recommended tied to GND for thermal relief).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Input supply connection | Accepts 2.6–24V; requires 1.0µF ceramic input capacitor placed adjacent to pin for stability. |
| 2 - GND | Power and signal reference | Common return path; must be connected to PCB ground plane and thermal pad for thermal management. |
| 3 - EN | Active-high enable input | Pulls high ≥2.0V to activate regulator; ≤0.4V disables output and reduces ground current to 0.01µA. |
| 4 - VOUT | Regulated output | Delivers 3.0V ±2%; requires 2.2µF ceramic output capacitor with ESR < 100mΩ for transient response. |
| 5 - ADJ/NC | Adjust/No-connect terminal | Internally disconnected for fixed 3.0V version; tie to GND to maximize copper area for thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Wide input voltage range | 2.6V–24V enables single-part support across battery chemistries and industrial rails. |
| Ultra-low quiescent current | 20µA at zero load extends runtime in battery-backed real-time clocks and sleep-mode sensors. |
| Low-noise regulated output | 30µVrms integrated noise (10Hz–100kHz) prevents interference in ADC references and RF receivers. |
| Thermal shutdown protection | Activates at TJ ≥ +150°C and auto-recovers upon cooling - prevents permanent damage during overload. |
| Lead-free & green compliance | Fully RoHS 3 compliant with <900ppm Br+Cl and <1000ppm Sb - meets automotive and medical regulatory requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT (Microchip) | 300mA rated, 175mV dropout @ 250mA, 3.0V ±1%, SOT-23-5, 1.6µA IQ | Higher current capacity but higher dropout at full load; lower IQ benefits deep-sleep systems. | Select when >150mA peak load or sub-2µA standby is required; verify thermal margin at 250mA in SOT-23-5. |
| NCP1117ST30T3G (onsemi) | 1A rated, 1.2V dropout @ 800mA, 3.0V ±2%, SOT-223, 6mA IQ | Higher power capability and thermal mass, but 300× higher ground current limits battery life. | Choose only for high-current, non-battery applications where board space allows SOT-223; avoid for portable use. |
Compared with MCP1700T-3002E/TT and NCP1117ST30T3G, the AP2204K-3.0TRG1 uniquely balances 150mA capability, 100mV ultra-low dropout, and 20µA ground current in the smallest SOT-23-5 footprint - making it optimal for compact, battery-sensitive designs where moderate current and minimal dropout dominate selection.

FAQ
What is the minimum input voltage required for regulation at 3.0V output?
The AP2204K-3.0TRG1 requires VIN ≥ VOUT + 1V = 4.0V for guaranteed regulation under all conditions. Below 4.0V, it enters dropout mode; however, it maintains regulation down to VIN = 3.1V (100mV dropout) at light loads (100µA), per datasheet specifications.
Can the ADJ/NC pin be left floating in the fixed 3.0V version?
No - Pin 5 (ADJ/NC) must be connected to GND. Although internally unconnected for fixed-output variants, tying it to GND maximizes PCB copper area for thermal dissipation and improves stability by reducing parasitic capacitance, as explicitly recommended in the datasheet.
Is the AP2204K-3.0TRG1 qualified for automotive applications?
The AP2204K-3.0TRG1 is not AEC-Q100 qualified. Diodes offers automotive-grade versions (e.g., AP2204Q series) with PPAP support and IATF 16949 manufacturing; this part is rated for -40°C to +85°C industrial operation only.
What capacitor types and values are mandatory for stable operation?
A 1.0µF X5R/X7R ceramic capacitor is required on VIN, and a 2.2µF X5R/X7R ceramic capacitor on VOUT, both with ESR < 100mΩ. Tantalum or aluminum electrolytics are not recommended due to instability risks and higher ESR.
