Product details
Overview
AP2210N-3.3TRG1 from Diodes Incorporated is a 300mA ultra-low dropout (ULDO) linear regulator with fixed 3.3V output, 250mV typical dropout at full load, ±1% output voltage accuracy, and 75dB PSRR at 100Hz. It delivers low-noise power to RF circuitry and battery-powered portable electronics requiring stable, clean supply rails.
For engineers reviewing the AP2210N-3.3TRG1 datasheet, AP2210N-3.3TRG1 pinout, AP2210N-3.3TRG1 application, or AP2210N-3.3TRG1 equivalent, this device is selected for noise-sensitive analog/RF subsystems, handheld communication devices, and space-constrained embedded systems where low quiescent current (1µA max shutdown), reverse current protection, and SOT-23-5 package compatibility are critical.
Technical Context
The AP2210N-3.3TRG1 employs a CMOS pass transistor architecture enabling ultra-low dropout and minimal ground current across load range (100µA–300mA). Its internal bandgap reference and error amplifier deliver tight line regulation (≤4.5mV) and load regulation (≤6mV) over temperature.
It integrates logic-compatible enable control (VIH = 2.0V, VIL = 0.4V), thermal shutdown, overcurrent limiting (450–900mA), and reverse current blocking-eliminating external diode requirements in battery backup paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1% - ensures stable core/logic rail without external feedback components. |
| Max Output Current | 300mA - supports moderate-power RF ICs, baseband processors, and sensor interfaces. |
| Dropout Voltage | 250mV at 300mA - enables operation from 3.55V input, extending battery runtime in single-cell Li-ion or 2xAA systems. |
| PSRR | 75dB at 100Hz - suppresses switching noise from upstream DC-DC converters feeding sensitive RF front-ends. |
| Standby Current | 1µA max - minimizes battery drain during system sleep modes in portable devices. |
| Operating Input Range | 4.3V to 13.2V - accommodates wide-input applications including automotive accessory rails and industrial 5V/12V supplies. |
| Thermal Protection | Internally limited junction temperature (150°C) - prevents latch-up or damage under sustained overload or poor PCB thermal design. |
Pinout & Package
AP2210N-3.3TRG1 is housed in a RoHS-compliant, lead-free SOT-23-5 package with matte tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input voltage supply | Accepts 4.3V–13.2V; requires 1.0µF ceramic input capacitor for stability and EMI suppression. |
| 2 (GND) | Ground reference | Low-impedance return path for regulator and load; must be connected directly to PCB ground plane. |
| 3 (EN) | Enable control input | CMOS/TTL-compatible; high ≥2.0V enables regulation, low ≤0.4V places device in 1µA shutdown mode. |
| 4 (BYP/ADJ) | Bypass capacitor terminal | Connects 100pF capacitor to GND to reduce output noise (260nV/√Hz) and improve PSRR performance. |
| 5 (VOUT) | Regulated output | Delivers 3.3V ±1% to load; requires 2.2µF ceramic output capacitor for transient response and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 250mV at 300mA enables use with marginal input margins-critical for Li-ion battery discharge curves. |
| Reverse Current Protection | Integrated MOSFET blocking eliminates need for external series diode, reducing BOM count and forward voltage loss. |
| Low-Noise Operation | 260nV/√Hz output noise with 100pF BYP capacitor meets stringent RF LNA and mixer supply requirements. |
| High PSRR | 75dB at 100Hz rejects ripple from noisy switchers, preserving signal integrity in mixed-signal SoC power domains. |
| Logic-Controlled Enable | CMOS/TTL-compatible EN pin allows direct interfacing with microcontroller GPIOs without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3302E/TO | 250mA max output, 600mV dropout at 250mA, no reverse current protection | Limited to lower-current digital logic rails; unsuitable for RF loads demanding <300mA or reverse-blocking | Select only if load current ≤250mA and reverse current path is externally managed. |
| Torex XC6206P332MR-G | 300mA output, 300mV dropout at 300mA, no enable pin, no reverse current protection | Requires external enable circuitry and blocking diode; higher dropout reduces battery efficiency | Choose only when enable control and reverse blocking are unnecessary and board space permits added discretes. |
Compared with MCP1700-3302E/TO and XC6206P332MR-G, AP2210N-3.3TRG1 uniquely combines 300mA drive, 250mV dropout, integrated enable, and reverse current blocking in a single SOT-23-5 package-making it optimal for compact, battery-critical RF and portable designs where reliability and efficiency are co-prioritized.

FAQ
What is the minimum input voltage required for AP2210N-3.3TRG1 to maintain regulation?
The minimum input voltage is 3.55V (3.3V + 250mV dropout) at 300mA load and +25°C. For reliable operation across temperature and load, Diodes recommends VIN ≥ 4.3V (VOUT + 1V) up to 13.2V. Below 4.3V, PSRR degrades significantly, risking noise coupling into sensitive circuits.
Does AP2210N-3.3TRG1 require an external bypass capacitor on the BYP pin?
Yes-a 100pF capacitor between BYP (Pin 4) and GND is mandatory to achieve specified 260nV/√Hz output noise and 75dB PSRR. Omitting it increases broadband noise by >10× and reduces low-frequency ripple rejection by 20–30dB, compromising RF system sensitivity.
Can AP2210N-3.3TRG1 be used in automotive applications?
AP2210N-3.3TRG1 is not AEC-Q100 qualified. While its operating junction temperature range (−40°C to +125°C) meets automotive ambient requirements, Diodes does not certify this variant for automotive use. For automotive-grade alternatives, contact Diodes' automotive sales team for PPAP-capable, IATF 16949-manufactured equivalents.
How does the enable pin behave during power-up and brown-out conditions?
The EN pin has no internal pull-up or pull-down. If left floating, the device may power up unpredictably. For deterministic behavior, tie EN to VIN through a resistor divider or drive it actively from a microcontroller. During brown-out, EN must remain ≥2.0V to sustain regulation; dropping below 0.4V forces shutdown and resets internal state.
