Product details
Overview
AP2204RB-5.0TRG1 from Diodes Incorporated is a fixed-output 5.0V ultra-low dropout (ULDO) linear regulator in SOT-89 (RB) package, designed for space-constrained portable electronics. It delivers 150mA output current with 100mV dropout at 100µA load, 60dB PSRR at 1kHz, ±2% output voltage accuracy, and operates across 2.6V–24V input range - ideal for USB-powered devices and battery-backed subsystems.
For engineers reviewing the AP2204RB-5.0TRG1 datasheet, AP2204RB-5.0TRG1 pinout, AP2204RB-5.0TRG1 application, or AP2204RB-5.0TRG1 equivalent, key selection criteria include dropout behavior under light-to-moderate loads, thermal performance in SOT-89 RB configuration, compatibility with ceramic output capacitors, and enable-controlled power sequencing in low-quiescent-current systems.
Technical Context
The AP2204RB-5.0TRG1 integrates a precision 1.24V bandgap reference, error amplifier, resistor network for fixed 5.0V output, current-limit protection, thermal shutdown, and an active-high enable input. Its EPNP process enables wide VIN operation while maintaining low ground current - as low as 20µA at zero load and 2.5mA at 150mA output.
It achieves stable regulation with only 1.0µF input and 2.2µF ceramic output capacitance, supports line regulation of 0.05% and load regulation of 0.5%, and exhibits ±100ppm/°C output voltage temperature coefficient over –40°C to +125°C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±2% - ensures stable MCU core or peripheral rail without external feedback components. |
| Input Voltage Range | 2.6V to 24V - supports single-cell Li-ion up to 24V industrial bus inputs without pre-regulation. |
| Max Output Current | 150mA - sufficient for microcontrollers, sensors, and interface ICs in portable designs. |
| Dropout Voltage | 100mV @ 100µA; 360mV @ 150mA - enables regulation down to VIN = 5.36V at full load, minimizing power loss. |
| PSRR | 60dB @ 1kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO. |
| Quiescent Current | 20µA @ no load; 2.5mA @ 150mA - extends battery life in always-on monitoring circuits. |
| Enable Threshold | VEN(HI) ≥ 2.0V, VEN(LO) ≤ 0.4V - compatible with 1.8V/3.3V logic-level control signals. |
Pinout & Package
SOT-89 (RB) package with exposed pad connected to GND for enhanced thermal dissipation (θJA = 165°C/W on 2-layer FR-4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection; accepts 2.6V–24V with internal overvoltage protection. |
| 2 | VOUT | Regulated 5.0V output; requires 2.2µF ceramic capacitor for stability and transient response. |
| 3 | GND | Power ground; tied to exposed pad for optimal thermal conduction and noise immunity. |
| Exposed Pad | GND | Thermal and electrical connection to PCB ground plane - mandatory for rated current and thermal reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 20µA at zero load - preserves battery capacity in standby and sleep modes. |
| Low-noise regulation | 30µVRMS output noise (10Hz–100kHz) - suitable for analog sensor signal chains and ADC references. |
| Thermal shutdown | Activates at +150°C junction temperature - prevents damage during overload or poor heatsinking. |
| Ceramic capacitor compatible | Stable with ≥2.2µF X5R/X7R MLCCs - eliminates need for larger, less reliable tantalum or electrolytic caps. |
| High accuracy output | ±2% over temperature and line/load - reduces need for post-regulation trimming in production calibration. |
Applications
| USB-Powered Peripherals | Industrial Sensor Nodes |
|---|---|
|
Use Scenario: USB 5V bus powers a BLE module, environmental sensor array, and flash memory in a compact field-deployable node. IC Role / Device Role / Timing Role: Primary 5.0V LDO supplying regulated rail to mixed-signal SoC and analog front-end. Use Value: 100mV dropout allows operation down to USB port sag (4.75V), while 60dB PSRR rejects USB switcher noise. |
Use Scenario: Remote vibration monitor powered by 12V industrial bus with local 5V logic and analog signal conditioning. IC Role / Device Role / Timing Role: Local point-of-load regulator for microcontroller and MEMS accelerometer interface. Use Value: 24V max input eliminates need for external TVS or pre-regulator; thermal shutdown protects against enclosure overheating. |
| Portable Medical Devices | Laptop Subsystem Power |
|

IC Role / Device Role / Timing Role: Low-noise, enable-controlled power stage enabling rapid wake/sleep transitions. Use Value: 30µVRMS noise avoids interference with photodiode signal path; 20µA IQ extends runtime between charges. |
Use Scenario: Secondary 5V rail for USB-C PD controller, EC firmware, and keyboard backlight in thin-and-light notebooks. IC Role / Device Role / Timing Role: Compact, thermally robust LDO replacing larger SO-8 alternatives in high-density layouts. Use Value: SOT-89 RB footprint saves >50% board area vs. PSOP-8; exposed pad enables 150mA continuous delivery in confined thermal zones. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-5002E/TT | 250mA rating, 1.6µA IQ, but only 6V max input and 600mV dropout @ 250mA. | Better for ultra-low-power coin-cell use; unsuitable for 12V+ industrial inputs or high-current loads. | Select when sub-µA quiescent current dominates over input voltage range and thermal headroom. |
| TPS7A2050PDBVR | 200mA, 6.5µA IQ, 300mV dropout @ 300mA, but 6.5V max input and no thermal shutdown. | Optimized for low-noise RF/analog rails; lacks overtemperature protection and wide-VIN capability. | Prefer for noise-sensitive signal chains where input stays below 5.5V and thermal margin is assured. |
Compared with MCP1700T-5002E/TT and TPS7A2050PDBVR, AP2204RB-5.0TRG1 uniquely balances 24V input tolerance, 150mA delivery, integrated thermal protection, and SOT-89 RB's thermal efficiency - making it the only choice for ruggedized 5V regulation in space- and thermal-constrained 12–24V systems.

FAQ
What is the minimum input voltage required for stable 5.0V regulation?
The minimum recommended input voltage is the greater of 2.6V or VOUT + 1V - i.e., 6.0V - to ensure regulation remains within specification. Below 6.0V, the device enters dropout and output voltage declines linearly with input. At 100µA load, regulation holds down to 5.1V due to 100mV dropout, but full 150mA capability requires ≥6.0V input.
Can AP2204RB-5.0TRG1 be used with ceramic output capacitors smaller than 2.2µF?
No - the datasheet specifies 2.2µF minimum for stability across all operating conditions. Using smaller values risks oscillation or degraded transient response. The device is optimized for X5R/X7R ceramics with ESR <100mΩ; lower-ESR types (e.g., C0G) require careful layout and may need series resistance per Diodes' application notes.
How does the exposed pad on the SOT-89 (RB) variant affect thermal performance?
The exposed pad must be soldered to a dedicated GND copper pour to achieve θJA = 165°C/W. Without this connection, junction temperature rises significantly - potentially exceeding 150°C at 150mA in still air. Thermal resistance drops to ~27°C/W (junction-to-case) when properly mounted, enabling full-rated current in typical 2-layer PCBs.
Is AP2204RB-5.0TRG1 qualified for automotive applications?
No - AP2204RB-5.0TRG1 is specified for –40°C to +85°C ambient and is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., AP2204x-xxQ) with PPAP support, IATF 16949 manufacturing, and extended temperature screening; those parts carry distinct part numbers and packaging markings.
