Product details
Overview
AP2210K-3.0TRE1 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-designed for noise-sensitive RF power rails in handheld wireless devices.
For engineers reviewing the AP2210K-3.0TRE1 datasheet, AP2210K-3.0TRE1 pinout, AP2210K-3.0TRE1 application, or AP2210K-3.0TRE1 equivalent, key selection criteria include low-noise operation (260nV/√Hz), 1µA shutdown current, SOT-23-5 package compatibility, and reverse-current protection for battery-backed systems.
Technical Context
The AP2210K-3.0TRE1 integrates a bandgap reference, thermal shutdown, current-limit circuitry, and CMOS/TTL-compatible enable logic. Its internal architecture delivers stable regulation under fast load transients while maintaining ultra-low noise via the BYP pin's 100pF bypass capacitor path.
It operates across -40°C to +125°C junction temperature, supports input voltages from 4.0V to 13.2V (VOUT + 1V minimum), and features reverse-current protection that blocks conduction when VIN < VOUT-critical for multi-rail sequencing in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% over -40°C to +125°C-ensures stable core/peripheral rail for 3.0V logic without external feedback. |
| Dropout Voltage | 250mV typical at 300mA-enables operation from 3.25V input, extending usable battery range in single-cell Li-ion or dual-cell alkaline systems. |
| PSRR | 75dB at 100Hz-suppresses switching noise from adjacent DC-DC converters feeding RF front-end ICs. |
| Standby Current | 1µA maximum in shutdown-preserves battery life during deep sleep modes in cellular handsets and IoT sensors. |
| Output Noise | 260nV/√Hz at 50mA-meets stringent spectral purity requirements for LNA, mixer, and PLL power domains. |
| Enable Threshold | VIH = 2.0V min, VIL = 0.4V max-directly interfaces with 1.8V/3.3V GPIO without level-shifting. |
| Thermal Protection | Internally limited junction temperature (150°C)-prevents latch-up during sustained overload or poor PCB thermal design. |
Pinout & Package
SOT-23-5 surface-mount package with matte tin-plated leads, RoHS-compliant, moisture sensitivity level 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input supply connection | Accepts 4.0V–13.2V input; requires 1.0µF ceramic decoupling close to pin for stability. |
| 2 (GND) | Ground reference | Low-impedance return path for both regulator quiescent current and 300mA load current; must connect to solid ground plane. |
| 3 (EN) | Enable control input | CMOS/TTL-compatible digital input; high ≥2.0V enables regulation, low ≤0.4V forces shutdown with 1µA ISTD. |
| 4 (BYP/ADJ) | Bypass capacitor terminal | Connects 100pF capacitor to GND to reduce output noise by filtering internal reference ripple-no ADJ function in fixed 3.0V version. |
| 5 (VOUT) | Regulated output | Delivers 3.0V ±1% at up to 300mA; requires 2.2µF low-ESR ceramic output capacitor for transient response and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 250mV at 300mA enables use with weak or depleting batteries while maintaining regulation. |
| Reverse current protection | Blocks backflow from VOUT to VIN during input brownout-eliminates need for external blocking diode. |
| 75dB PSRR at 100Hz | Attenuates low-frequency ripple from buck converter outputs, critical for RF signal chain integrity. |
| 260nV/√Hz output noise | Meets noise floor requirements of sensitive analog RF blocks without additional LDO staging. |
| Logic-compatible EN pin | Direct interface with microcontroller GPIO pins operating at 1.8V or 3.3V logic levels-no external pull-up or buffer needed. |
Applications
| Cellular Handset Power Rail | Wireless Audio Transceiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | 250mA output, 600mV dropout at 250mA, 65dB PSRR at 100Hz, no reverse-current protection | Lacks reverse-current blocking; requires external diode in battery backup configurations | Choose if cost sensitivity outweighs reverse-current protection and PSRR requirements |
| Torex XC6206P302MR-G | 300mA output, 300mV dropout at 300mA, 70dB PSRR at 100Hz, 2.5µA standby current | Higher dropout and standby current reduce battery runtime in deep-sleep IoT nodes | Prefer only if SOT-23-3 footprint is mandatory and 50mV higher dropout is acceptable |
Compared with MCP1700-3002E/TO and XC6206P302MR-G, AP2210K-3.0TRE1 uniquely combines reverse-current protection, lowest dropout (250mV), and industry-leading 75dB PSRR-making it optimal for RF-critical, battery-constrained applications where reliability and noise immunity are non-negotiable.

FAQ
What is the minimum input voltage required for AP2210K-3.0TRE1 to maintain regulation?
The minimum input voltage is 4.0V-defined as VOUT + 1V per datasheet Note 4. At 300mA load, the 250mV typical dropout requires VIN ≥ 3.25V to sustain 3.0V output, but 4.0V is recommended to ensure full PSRR performance and avoid degradation near dropout boundary.
Can the BYP pin be left unconnected in the AP2210K-3.0TRE1?
No. The BYP pin must be connected to a 100pF capacitor to GND to achieve the specified 260nV/√Hz output noise and 75dB PSRR. Leaving it open degrades noise performance and may cause instability under certain load conditions.
Does AP2210K-3.0TRE1 require an external output capacitor, and what type is recommended?
Yes. A minimum 2.2µF ceramic capacitor with X5R or X7R dielectric and ≤100mΩ ESR is required at VOUT for stability and transient response. Tantalum or aluminum electrolytic capacitors are not recommended due to higher ESR and potential reliability issues.
How does the reverse-current protection function in AP2210K-3.0TRE1?
Internal circuitry blocks current flow from VOUT to VIN when VIN falls below VOUT-such as during battery swap or input capacitor discharge. This eliminates the need for an external series diode, reducing voltage loss and board space while preventing unintended discharge of backup supplies.
