Product details
Overview
AP2210N-2.8TRE1 from Diodes Incorporated is a 300mA ultra-low dropout (ULDO) linear regulator with fixed 2.8V output, 250mV typical dropout at full load, ±1% output voltage accuracy, 75dB PSRR at 100Hz, and 1µA maximum standby current. It operates from 2.5V to 13.2V input and delivers stable, low-noise power for RF front-end stages and battery-powered portable electronics.
For engineers reviewing the AP2210N-2.8TRE1 datasheet, AP2210N-2.8TRE1 pinout, AP2210N-2.8TRE1 application, or AP2210N-2.8TRE1 equivalent, this device is selected for noise-sensitive analog/RF subsystems requiring high PSRR, tight regulation, logic-controlled enable, and reverse-current protection in space-constrained SOT-23-3 layouts.
Technical Context
The AP2210N-2.8TRE1 uses a PMOS pass transistor architecture enabling ultra-low dropout and inherent reverse-current blocking without external components. Its bandgap reference and error amplifier deliver ±1% initial accuracy and 42.8 ppm/°C temperature coefficient over –40°C to +125°C.
It integrates CMOS/TTL-compatible enable control, thermal shutdown, overcurrent limiting (450–900mA), and internal bypass capacitor support via the BYP pin-though this pin is omitted in the SOT-23-3 variant. The regulator maintains 75dB ripple rejection at 100Hz with only 100µA load and requires no ESR-stabilizing output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±1% - ensures precise biasing of 2.8V-tolerant RF ICs and baseband processors. |
| Dropout Voltage | 250mV typ. at 300mA - enables operation from 3.05V input, critical for single-cell Li-ion (3.0–3.6V) systems. |
| PSRR | 75dB at 100Hz - suppresses switching noise from adjacent DC-DC converters feeding noisy supply rails. |
| Standby Current | 1µA max. - extends battery life during system sleep modes in handheld and IoT edge devices. |
| Output Accuracy | ±1% over temperature - eliminates need for post-regulation trimming in production calibration. |
| Thermal Protection | Internally limited junction temperature (150°C) - prevents latch-up or damage during transient overload or poor PCB heatsinking. |
| Enable Threshold | VIH = 2.0V min., VIL = 0.4V max. - compatible with 1.8V/3.3V GPIO without level-shifting. |
Pinout & Package
SOT-23-3 package: 1.45mm × 2.9mm footprint, matte tin-plated leads, moisture sensitivity level 3 (J-STD-020), RoHS and halogen-free compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply rail; must be ≥ VOUT + 250mV for regulation; decoupled with 1.0µF ceramic. |
| 2 | GND | Power ground return path; low-impedance connection required to minimize noise coupling into feedback loop. |
| 3 | VOUT | Regulated 2.8V output; supplies noise-sensitive loads directly; bypassed with 2.2µF ceramic for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 250mV at 300mA enables use with aging or partially discharged batteries while maintaining regulation. |
| High PSRR | 75dB at 100Hz rejects low-frequency ripple from buck converter switching edges and AC-DC adapters. |
| Reverse Current Protection | PMOS pass element blocks backflow when VIN < VOUT - prevents battery drain through load paths during power-off. |
| Logic-Controlled Enable | CMOS/TTL-compatible EN input allows microcontroller-driven power sequencing and dynamic rail management. |
| Low Standby Current | 1µA shutdown current minimizes quiescent loss in always-on sensor nodes and real-time clock circuits. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ULDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-2802E/TO | 250mA output, 600mV dropout at 250mA, 65dB PSRR at 100Hz, no reverse-current protection | Limited to lower current and higher dropout; unsuitable for 300mA RF loads or reverse-battery scenarios | Select only if cost is primary constraint and load current ≤250mA with relaxed PSRR requirements. |
| Torex XC6210B282MR-G | 300mA output, 160mV dropout at 300mA, 70dB PSRR at 100Hz, 2.5µA standby current | Lower dropout but higher quiescent current; lacks integrated thermal foldback | Prefer for ultra-low-input applications (e.g., 2.95V min.), but avoid where <1µA shutdown is mandatory. |
Compared with MCP1700-2802E/TO and XC6210B282MR-G, the AP2210N-2.8TRE1 uniquely combines 300mA capability, 250mV dropout, 75dB PSRR, 1µA shutdown, and reverse-current blocking in a single SOT-23-3 package-making it optimal for battery-fed RF and portable systems demanding both efficiency and noise immunity.

FAQ
What is the minimum input voltage required for AP2210N-2.8TRE1 to maintain regulation at 300mA load?
The minimum input voltage is VOUT + VDROP = 2.8V + 0.25V = 3.05V under typical conditions. However, the datasheet recommends VIN ≥ VOUT + 1V (i.e., ≥3.8V) to ensure full PSRR performance and margin against worst-case dropout (up to 400mV at 300mA over temperature).
Does AP2210N-2.8TRE1 require an external bypass capacitor on the BYP pin?
No. The BYP/ADJ pin is present only in the SOT-23-5 version for adjustable output or noise filtering. The AP2210N-2.8TRE1 uses the SOT-23-3 package, which omits the BYP pin entirely; noise performance is achieved internally without external components.
Can AP2210N-2.8TRE1 be used in automotive applications?
While not AEC-Q100 qualified, the AP2210N-2.8TRE1 operates across –40°C to +125°C junction temperature and meets key automotive electrical requirements. For certified automotive use, Diodes offers AEC-Q100 variants (e.g., AP2210Q) with PPAP support and IATF 16949 manufacturing.
How does the reverse-current protection function without external circuitry?
The AP2210N-2.8TRE1 uses a PMOS pass transistor with source tied to VIN and drain to VOUT. When VIN falls below VOUT, the body diode is reverse-biased and the gate drive is cut off, preventing conduction-eliminating need for external Schottky diodes or ideal diode controllers.
