Product details
Overview
AP2210K-5.0TRG1 from Diodes Incorporated is a 300mA ultra-low dropout (ULDO) linear regulator with fixed 5.0V output, 250mV typical dropout at full load, ±1% output voltage accuracy, and 75dB PSRR at 100Hz. It delivers low-noise power for RF front-end circuits and battery-powered portable electronics requiring stable, clean 5V supply under tight input headroom constraints.
For engineers reviewing the AP2210K-5.0TRG1 datasheet, AP2210K-5.0TRG1 pinout, AP2210K-5.0TRG1 application, or AP2210K-5.0TRG1 equivalent, key selection criteria include dropout performance at 300mA, standby current ≤1µA, thermal shutdown behavior, reverse current protection, and SOT-23-5 package compatibility with bypass capacitor routing for noise-sensitive analog/RF rails.
Technical Context
The AP2210K-5.0TRG1 uses a PNP pass transistor architecture enabling ultra-low dropout and inherent reverse current blocking without external diodes. Its bandgap reference and error amplifier deliver tight line/load regulation (<6mV) and low temperature coefficient (120µV/°C).
It integrates CMOS/TTL-compatible enable control, thermal shutdown, overcurrent limiting (450–900mA), and internal bypass node (BYP/ADJ pin) for external 100pF capacitor to reduce output noise to 260nV/√Hz. The device operates across -40°C to +125°C junction temperature with input range 2.5V–13.2V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1% - ensures stable logic-level supply for microcontrollers and RF ICs without external feedback resistors. |
| Max Output Current | 300mA - supports moderate-power RF modules, sensor interfaces, and baseband processors in compact handheld designs. |
| Dropout Voltage | 250mV typ. at 300mA - enables operation from 5.25V input, critical for single-cell Li-ion or dual-cell alkaline systems. |
| PSRR | 75dB at 100Hz - suppresses switching noise from upstream DC-DC converters feeding sensitive RF receivers or ADC references. |
| Standby Current | ≤1µA max - extends battery life during system sleep modes in portable communication devices. |
| Thermal Protection | Internally limited junction temperature (150°C) - prevents latch-up or damage during sustained overload or poor PCB thermal design. |
| Reverse Current Protection | Integrated - eliminates need for external blocking diode, reducing BOM count and forward voltage loss in backup power paths. |
Pinout & Package
SOT-23-5 surface-mount package with 0.95mm pitch, matte tin-plated leads, RoHS-compliant and halogen-free ("Green") construction. Moisture sensitivity level 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VIN) | Input voltage supply | Accepts 2.5V–13.2V; must be decoupled with ≥1.0µF ceramic capacitor close to pin for stability and transient response. |
| 2 (GND) | Ground reference | Low-impedance return path for load, quiescent, and enable currents; connects internally to die substrate and thermal pad. |
| 3 (EN) | Enable control input | CMOS/TTL-compatible; logic high (≥2.0V) enables regulation, logic low (≤0.4V) places device in 1µA shutdown mode. |
| 4 (BYP/ADJ) | Bypass/adjust node | For fixed 5.0V version: connect 100pF capacitor to GND to minimize output noise; not used for voltage setting. |
| 5 (VOUT) | Regulated output | Delivers 5.0V ±1% with <6mV load regulation; requires ≥2.2µF low-ESR ceramic output capacitor for stability and PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 250mV at 300mA enables use with minimal input–output differential, preserving battery runtime in space-constrained portable gear. |
| High PSRR (75dB @100Hz) | Effectively filters ripple from noisy switchers, supporting clean power for RF transceivers and precision analog signal chains. |
| Logic-Controlled Enable | Direct interface to MCU GPIO without level-shifting; allows dynamic power gating of subsystems to meet ultra-low-power sleep budgets. |
| Integrated Reverse Current Protection | Eliminates external Schottky diode, saving board area and avoiding ~300mV forward drop in backup or dual-supply configurations. |
| Thermal & Overcurrent Protection | Auto-recovering shutdown prevents permanent damage during short-circuit events or inadequate heatsinking on small PCBs. |
Applications
| Cellular Front-End Power | Portable RF Transceiver Supply |

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 |
|---|---|---|---|
| MCP1700-5002E/TO | 250mA max output, 600mV dropout at 250mA, no enable pin, TO-92 package | Lacks logic control and reverse current protection; suited for non-battery, non-RF applications with ample input headroom | Select only if enable functionality and reverse blocking are unnecessary and through-hole mounting is required. |
| Torex XC6206P502MR-G | 300mA output, 300mV dropout at 300mA, no enable, SOT-23-3 (3-pin) package | Omits EN and BYP pins; smaller footprint but no shutdown control or noise optimization capability | Choose when board space is critical and system-level enable control is handled externally or not needed. |
Compared with MCP1700-5002E/TO and XC6206P502MR-G, the AP2210K-5.0TRG1 uniquely combines 300mA capability, 250mV dropout, integrated enable, reverse current blocking, and BYP-capable noise reduction-making it the only option among the three suitable for battery-powered RF subsystems requiring dynamic power management and ultra-clean 5V rails.

FAQ
What is the minimum input voltage required for AP2210K-5.0TRG1 to maintain regulation at 300mA load?
The minimum input voltage is 5.25V, calculated as VOUT + VDROP = 5.0V + 0.25V. At 300mA and +25°C, the typical dropout is 250mV; the datasheet recommends VIN ≥ VOUT + 1V (i.e., ≥6.0V) for optimal PSRR and thermal margin, but regulation is maintained down to 5.25V.
Can the BYP/ADJ pin be left floating in the AP2210K-5.0TRG1 fixed-output version?
No. For the fixed 5.0V version, the BYP/ADJ pin must be connected to a 100pF capacitor to ground to achieve specified 260nV/√Hz output noise performance. Leaving it floating degrades PSRR and increases broadband noise, compromising RF and precision analog applications.
Does AP2210K-5.0TRG1 require an external diode for reverse polarity protection?
No. The device integrates reverse current protection, blocking current flow from VOUT to VIN when input voltage falls below output voltage. This eliminates the need for an external series diode, preserving efficiency and board space in battery backup or hot-swap configurations.
How does thermal shutdown behave during sustained overload conditions?
When junction temperature exceeds +150°C, the AP2210K-5.0TRG1 enters thermal shutdown, disabling the pass element and reducing output current to near zero. It automatically recovers once TJ drops below +135°C (typical hysteresis), enabling fault-tolerant operation without manual reset in intermittently overloaded systems.
