Product details
Overview
AP2210N-3.0TRG1 from Diodes Incorporated is a 300mA ultra-low dropout (ULDO) linear regulator with fixed 3.0V output, 250mV typical dropout at full load, ±1% output voltage accuracy, and 75dB PSRR at 100Hz. It delivers low-noise power for RF front-ends and battery-powered portable electronics requiring stable 3.0V supply under tight input headroom constraints.
For engineers reviewing the AP2210N-3.0TRG1 datasheet, AP2210N-3.0TRG1 pinout, AP2210N-3.0TRG1 application, or AP2210N-3.0TRG1 equivalent, this device supports noise-sensitive analog/RF circuitry, enables extended battery life via 1µA shutdown current, and integrates overcurrent, thermal, and reverse-current protection in SOT-23-3 packaging.
Technical Context
The AP2210N-3.0TRG1 uses a CMOS pass transistor architecture to achieve ultra-low dropout and high PSRR without external compensation. Its bandgap reference and error amplifier deliver tight line/load regulation (≤4.5mV/≤6mV) across -40°C to +125°C operating junction temperature.
Logic-compatible enable input (VIH = 2.0V, VIL = 0.4V) controls CMOS/TTL-compatible shutdown mode, reducing quiescent current to ≤1µA. The internal bypass path minimizes output noise to 260nV/√Hz when paired with a 100pF BYP-to-GND capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% - ensures stable core logic or RF IC biasing without external feedback components. |
| Dropout Voltage | 250mV typ. at 300mA - allows operation from 4.0V input (VOUT+1V), enabling use with single-cell Li-ion or 2xAA alkaline sources. |
| PSRR | 75dB at 100Hz - suppresses switching noise from upstream DC/DC converters feeding sensitive RF receivers or ADCs. |
| Standby Current | ≤1µA in shutdown - extends battery runtime in always-on wireless sensor nodes or standby modes of handheld devices. |
| Output Noise | 260nV/√Hz - meets low-noise requirements for LNA biasing, PLL VCO supplies, and precision analog signal chains. |
| Thermal Protection | Internally limited junction temperature (TJ ≤ +150°C) - prevents latch-up during transient overload or poor PCB thermal design. |
| Enable Threshold | VIL ≤ 0.4V / VIH ≥ 2.0V - interfaces directly with 3.3V or 1.8V microcontroller GPIO without level-shifting. |
Pinout & Package
SOT-23-3 package: 2.92mm × 1.3mm × 1.0mm body, matte tin-plated leads, moisture sensitivity level 3 per J-STD-020.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply pin; accepts 4.0V–13.2V input with internal overvoltage clamp at 15V absolute max. |
| 2 | GND | Power ground reference for regulator control loop and output stage; requires low-impedance PCB connection. |
| 3 | VOUT | Regulated 3.0V output; connects to local decoupling (2.2µF ceramic) and load; reverse-current protected. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 250mV at 300mA enables operation with minimal input–output differential, critical for battery voltage sag scenarios. |
| High PSRR | 75dB at 100Hz rejects ripple from noisy switchers, preserving signal integrity in RF transceivers and audio codecs. |
| Reverse Current Protection | Prevents backflow from VOUT to VIN during shutdown or input removal-eliminates need for external blocking diode. |
| Logic-Controlled Enable | CMOS/TTL-compatible EN input (not present on SOT-23-3 variant; AP2210N-3.0TRG1 is SOT-23-3, so no EN pin - this feature applies only to SOT-23-5 version; correction: AP2210N-3.0TRG1 is SOT-23-3, thus has no EN or BYP pins - only VIN, GND, VOUT) |
| ±1% Output Accuracy | Tight initial tolerance ensures reliable operation of 3.0V I/O interfaces, memory, and mixed-signal SoCs without calibration. |

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 |
|---|---|---|---|
| MCP1700-3002E/TO | 250mA output, 1.6µA quiescent current, no reverse-current protection, TO-92 package. | Limited to lower-current sensor interfaces; lacks reverse-current blocking needed for multi-rail systems. | Select when ultra-low IQ dominates over output current capability and reverse-current safety. |
| TPS7A2030PDQNR | 300mA output, 6.5µA IQ, 165mV dropout at 300mA, WSON-6 package, integrated thermal foldback. | Superior dropout and smaller footprint but requires BYP capacitor and lacks SOT-23-3 compatibility. | Select when board space is constrained and lowest possible dropout is required, accepting larger assembly complexity. |
Compared with MCP1700-3002E/TO, AP2210N-3.0TRG1 delivers 33% higher output current and built-in reverse-current protection; versus TPS7A2030PDQNR, it offers drop-in SOT-23-3 replacement with proven RF noise performance but slightly higher dropout and no thermal foldback.

FAQ
What is the minimum input voltage required for AP2210N-3.0TRG1 to maintain regulation?
The recommended minimum input voltage is 4.0V (VOUT + 1V), based on the typical 250mV dropout at 300mA. At 300mA load and +25°C, input below 4.0V risks output droop and degraded PSRR. Absolute minimum is 3.25V (VOUT + 250mV), but operation near dropout reduces noise rejection and thermal margin.
Does AP2210N-3.0TRG1 include an enable pin?
No. AP2210N-3.0TRG1 uses the SOT-23-3 package and has only three terminals: VIN, GND, and VOUT. Enable functionality is exclusive to the SOT-23-5 variant (e.g., AP2210-3.0WTBG). This part operates continuously when input voltage is applied within specification.
Can AP2210N-3.0TRG1 be used with ceramic output capacitors?
Yes. The device is optimized for stability with 2.2µF X5R/X7R ceramic capacitors (ESR < 100mΩ). No series resistor is required. Using ceramic caps improves transient response and reduces board area versus tantalum alternatives, aligning with its "excellent ESR stability" design feature.
How does the reverse-current protection function in AP2210N-3.0TRG1?
Internal circuitry blocks current flow from VOUT to VIN when VIN falls below VOUT, such as during input power removal or brownout. This eliminates the need for an external Schottky diode, prevents battery drain in multi-supply systems, and avoids unintended powering of upstream circuits through the LDO output pin.
