Product details
Overview
AP130-25RG-7 from Diodes Incorporated is a fixed 2.5V, 300mA low-dropout linear regulator in SC59R package with 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element, thermal shutdown, and current-limit protection for battery-powered peripherals requiring stable low-noise voltage regulation.
For engineers reviewing the AP130-25RG-7 datasheet, AP130-25RG-7 pinout, AP130-25RG-7 application, or AP130-25RG-7 equivalent, key selection criteria include dropout performance at 300mA, SC59R footprint compatibility, 2.5V output tolerance, thermal resistance (θJA = 250°C/W), and green RoHS-compliant packaging.
Technical Context
The AP130-25RG-7 uses a PMOS pass transistor with no base current draw, enabling ultra-low quiescent current across load range. Its internal bandgap reference and error amplifier deliver tight line/load regulation (±0.3%/V and ±40mV) under varying input and output conditions.
Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered at ~125°C junction temperature. The device requires ≥10µF output capacitance for stability and achieves 58dB PSRR at 100Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V ±2% - ensures precise rail generation for 2.5V logic or analog circuitry without external feedback. |
| Max Output Current | 300mA - supports moderate-power peripherals like USB interface ICs or sensor signal chains. |
| Dropout Voltage | 400mV (typ) at 300mA - enables operation down to 2.9V input for single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 50µA (typ) - minimizes standby power loss in always-on battery applications such as remote sensors. |
| PSRR | 58dB at 100Hz - suppresses low-frequency ripple from switching supply stages upstream of LDO. |
| Thermal Resistance θJA | 250°C/W (SC59R) - defines maximum power dissipation limit (≈125mW at ΔT=31.25°C) on standard FR-4 PCB. |
| Protection Features | Current limit + thermal shutdown - prevents permanent damage during sustained overload or ambient overheating. |
Pinout & Package
AP130-25RG-7 is housed in SC59R package: 3-pin, lead-free, green molding compound, surface-mount plastic case (JEDEC TO-236AB). Dimensions: 2.90 × 1.30 × 1.00 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground Reference | Return path for internal bias and error amplifier; must connect to low-impedance system ground plane. |
| 2 (OUT) | Regulated Output | Delivers stable 2.5V to load; requires ≥10µF ceramic capacitor to ground for loop stability. |
| 3 (IN) | Power Input | Accepts 2.7–5.5V input; minimum headroom of 400mV required above 2.5V for regulation at 300mA. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | Zero gate drive current eliminates base/leakage losses, enabling 50µA IQ independent of load. |
| Fast Transient Response | Stabilizes within <10µs after 100mA step load change - critical for burst-mode digital loads. |
| Green Molding Compound | Halogen-free (no Br/Sb) - meets IPC-4101D/21 requirements for environmentally compliant PCB assembly. |
| Short-Circuit Fold-Back | Reduces output current to 150–300mA during fault - limits power dissipation and junction temperature rise. |
| RoHS Compliant Finish | Lead-free matte tin plating - compatible with Pb-free reflow profiles (J-STD-020D, peak 260°C). |
Applications
| Battery-Powered Wireless Sensor Node | USB Peripheral Interface Card |

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 |
|---|---|---|---|
| MCP1700-2502E/TO | 250mA max output, 175mV dropout at 250mA, SOT23-3 package, 2.5V ±1% accuracy | Limited current headroom for 300mA peaks; lower thermal resistance (200°C/W) but smaller pad area | Select when tighter voltage tolerance (±1%) and lower dropout outweigh current margin needs. |
| AP2204-2.5TRG1 | 300mA output, 350mV dropout at 300mA, SOT23-3, 2.5V ±2%, 65µA IQ | Higher quiescent current reduces battery life; same SC59R pinout not supported - different footprint | Choose only if SOT23-3 layout reuse is mandatory and 15µA IQ penalty is acceptable. |
Compared with MCP1700-2502E/TO and AP2204-2.5TRG1, AP130-25RG-7 uniquely balances 300mA capability, SC59R package compatibility, and 50µA IQ - making it optimal for space-constrained, long-life battery designs where both current headroom and ultra-low standby loss are required.

FAQ
What is the minimum input voltage required for AP130-25RG-7 to maintain regulation at 300mA?
The AP130-25RG-7 requires a minimum input voltage of 2.9V to sustain 2.5V output at 300mA load, based on its typical 400mV dropout voltage. Below this threshold, output voltage drops linearly with input; operation below 2.7V violates absolute maximum ratings and may cause undefined behavior.
Can AP130-25RG-7 be used with ceramic output capacitors?
Yes - the AP130-25RG-7 is stable with ceramic output capacitors ≥10µF and ESR ≤100mΩ. The datasheet specifies 10µF as minimum for phase margin >45°; X5R/X7R types are recommended to maintain capacitance across temperature and DC bias.
Does AP130-25RG-7 support reverse polarity protection?
No - the AP130-25RG-7 lacks built-in reverse-input protection. Applying negative voltage to IN or positive voltage to GND exceeds absolute maximum ratings (VIN = –0.3V) and risks permanent damage. External diode or MOSFET protection must be added if reverse polarity is possible.
How does thermal shutdown behave during continuous overload?
When junction temperature reaches ~125°C, thermal shutdown disables the pass element, dropping output to near-zero. After cooling to ~110°C (typical hysteresis), the device automatically recovers regulation. This cycle repeats until fault condition is removed, preventing irreversible silicon damage.
