Product details
Overview
AP2213D-3.3TRG1 from Diodes Incorporated is a fixed 3.3V, 500mA low-noise LDO regulator featuring 350mV dropout at full load, ±1% output voltage accuracy, and 75dB PSRR at 100Hz. It integrates logic-compatible enable control, reversed current protection, and thermal shutdown, and is deployed in RF front-ends and portable battery-powered systems where clean, stable 3.3V rail integrity is critical.
For engineers reviewing the AP2213D-3.3TRG1 datasheet, AP2213D-3.3TRG1 pinout, AP2213D-3.3TRG1 application, or AP2213D-3.3TRG1 equivalent, key selection criteria include dropout performance under 500mA load, standby current ≤1µA, noise sensitivity mitigation via BYP pin, and compatibility with 100pF bypass capacitor for <260nV/√Hz output noise.
Technical Context
The AP2213D-3.3TRG1 employs a bandgap-referenced PMOS pass transistor architecture enabling ultra-low dropout and reversed current blocking. Its internal reference is decoupled via the dedicated BYP terminal, allowing external 100pF capacitor placement to suppress reference noise and reduce integrated output noise to 260nV/√Hz.
Enable functionality is TTL/CMOS compatible (VIH ≥ 2.0V, VIL ≤ 0.4V), supporting precise power sequencing. Protection circuitry includes foldback current limiting (700–1000mA trip), thermal shutdown at +150°C junction, and over-temperature hysteresis for safe recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1% (ensures stable I/O or core rail for 3.3V microcontrollers and RF ICs) |
| Max Output Current | 500mA continuous (supports moderate-power peripherals without external boost) |
| Dropout Voltage | 350mV at 500mA (enables operation from 3.65V input, e.g., single-cell Li-ion with aging margin) |
| PSRR | 75dB at 100Hz (rejects low-frequency supply ripple from switching converters feeding the LDO) |
| Standby Current | ≤1µA in shutdown (extends battery life in always-on sensor nodes or sleep-mode devices) |
| Output Noise | 260nV/√Hz (measured with 100pF BYP-to-GND; critical for ADC references and RF synthesizers) |
| Thermal Resistance θJA | 90°C/W (TO-252-2 package; defines max power dissipation limit without heatsink at given ambient) |
Pinout & Package
AP2213D-3.3TRG1 is packaged in TO-252-2 (3) - a thermally enhanced surface-mount outline with exposed drain pad for PCB heat sinking. Pin 1 = VIN, Pin 2 = VOUT, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 4.3V–18V input; must be ≥3.65V for regulated 3.3V output at 500mA |
| VOUT | Regulated output | Delivers precise 3.3V ±1%; requires ≥2.2µF ceramic output capacitor when BYP is used |
| GND | Power ground reference | Common return for VIN, VOUT, EN, and BYP; must be low-impedance to minimize noise coupling |
| EN | Enable control input | Active-high logic interface (2.0–18V); pulls regulator into 1µA shutdown when ≤0.4V |
| BYP | Noise bypass terminal | Connects to internal bandgap reference; 100pF to GND reduces output noise but narrows ESR stability range |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 260nV/√Hz output noise with 100pF BYP capacitor-enables high-resolution analog signal chains |
| Reversed current protection | Blocks reverse current flow from VOUT to VIN during input brownout or hot-swap-prevents system backfeeding |
| Tight line/load regulation | ≤4.5mV line regulation (VIN = 4.3–13.2V) and ≤9mV load regulation (0.1–500mA)-maintains voltage stability across dynamic loads |
| Ultra-low quiescent current | 100–20µA ground pin current across 100µA–500mA load-minimizes overhead in battery-critical designs |
| Robust protection suite | Integrated thermal shutdown, current limiting (700–1000mA), and over-temperature hysteresis-ensures fault resilience without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1703T-3302E/MB | Higher dropout (600mV @ 250mA), no BYP pin, 1.8µA quiescent current | Lacks noise optimization capability; unsuitable for RF or high-precision ADC use | Prefer AP2213D-3.3TRG1 when PSRR >70dB or output noise <300nV/√Hz is required |
| TLS850F3BTV50 | Automotive-grade (AEC-Q100), higher IQ (20µA), integrated watchdog and reset | Designed for 12V automotive systems with cold-crank support; not optimized for portable battery life | Choose AP2213D-3.3TRG1 for cost-sensitive industrial/portable designs without AEC-Q100 requirement |
Compared with MCP1703T-3302E/MB and TLS850F3BTV50, AP2213D-3.3TRG1 uniquely balances ultra-low noise (260nV/√Hz), low dropout (350mV), and sub-1µA shutdown-making it optimal for noise-sensitive, battery-constrained applications where feature integration is secondary to analog performance.

FAQ
What is the minimum input voltage required for AP2213D-3.3TRG1 to maintain regulation at 500mA?
The minimum input voltage is 3.65V, calculated as VOUT + VDROP = 3.3V + 0.35V. Below this, output voltage drops >1% from nominal. The recommended operating range is 4.3V to 18V per datasheet Section 4, ensuring robust PSRR and thermal margin.
Can the BYP pin be left unconnected, and what is the impact on performance?
Yes, BYP can be left open. Doing so eliminates the 100pF noise filter, increasing output noise to ~500nV/√Hz (inferred from typical AP2213 noise curves), but widens the stable ESR range for output capacitors and improves startup time. Use open BYP only when noise is non-critical and transient response speed is prioritized.
Does AP2213D-3.3TRG1 require an input capacitor, and what value is recommended?
Yes-a minimum 1.0µF ceramic capacitor is required between VIN and GND per datasheet Section 13. This stabilizes input impedance, suppresses high-frequency noise from upstream converters, and prevents oscillation during load transients. X7R or better dielectric is recommended for temperature stability.
How does thermal performance differ between TO-252-2 and SOIC-8 packages for AP2213D-3.3TRG1?
TO-252-2 offers θJA = 90°C/W versus SOIC-8's 160°C/W. At 500mA and 3.65V input, power dissipation is ~175mW; TO-252-2 limits junction rise to ~16°C above ambient, while SOIC-8 rises ~28°C. For ambient >85°C or sustained full-load operation, TO-252-2 is strongly preferred to avoid thermal shutdown.
