Product details
Overview
AP130-15RG-7 from Diodes Incorporated is a 300mA fixed-output 1.5V low-dropout linear regulator in SC59R package, featuring 400mV dropout at full load, ±2% output voltage accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and current-limit protection-designed for battery-powered portable electronics requiring stable low-voltage rail generation.
For engineers reviewing the AP130-15RG-7 datasheet, AP130-15RG-7 pinout, AP130-15RG-7 application, or AP130-15RG-7 equivalent, key selection criteria include dropout performance at 300mA, thermal resistance (θJA = 250°C/W), SC59R pin compatibility, and green/RoHS-compliant packaging for space-constrained PCB layouts.
Technical Context
The AP130-15RG-7 employs an internal PMOS pass transistor with RON = 1.5Ω, enabling low dropout and zero gate-drive current. Its error amplifier uses a 1.08V bandgap reference to regulate output within ±2% across -40°C to +85°C ambient.
Protection circuitry includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered above +125°C junction temperature. PSRR reaches 58dB at 100Hz with 1µF input and 10µF output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% - ensures stable core voltage for 1.5V logic or analog subsystems without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power microcontrollers, sensors, or interface ICs in portable designs. |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 1.9V input, critical for single-cell Li-ion or alkaline battery systems. |
| Quiescent Current | 50µA typ. at zero load - minimizes standby power loss in always-on or battery-backed applications. |
| Line Regulation | 0.1–0.3%/V - maintains tight output stability despite input voltage sag during battery discharge or transient load steps. |
| PSRR | 58dB at 100Hz - suppresses ripple from switching supply stages upstream, improving noise-sensitive analog performance. |
| Thermal Resistance θJA | 250°C/W (SC59R) - defines maximum power dissipation limit (≈125mW at ΔT=31.25°C) on standard FR-4 board without heatsink. |
Pinout & Package
AP130-15RG-7 is housed in SC59R package: 3-pin, lead-free, green molding compound, surface-mount plastic case with gull-wing leads. Dimensions: 2.90×1.30×1.00 mm (L×W×H), 0.95 mm lead pitch.
| 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 fixed 1.5V to load; requires ≥10µF ceramic capacitor to ground for stability per datasheet. |
| 3 (IN) | Input Supply | Accepts 2.7–5.5V input; minimum 1µF bypass capacitor recommended to suppress high-frequency noise. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | RON = 1.5Ω eliminates base drive current, reducing total system quiescent consumption vs. NPN-based LDOs. |
| Fast Transient Response | Stabilizes within microseconds after 100mA load step - preserves voltage integrity for burst-mode digital loads. |
| Short-Circuit Fold-Back | Limits output current to 150–300mA during fault, reducing power dissipation and preventing thermal runaway. |
| Green Molding Compound | Halogen-free (no Br/Sb) and RoHS-compliant - meets IPC-1752A material declaration requirements for eco-design. |
| Thermal Shutdown | Activates at TJ > +125°C and auto-recovers upon cooling - protects device and PCB during sustained overload or poor airflow. |
Applications
| Portable Medical Sensors | USB Peripheral Controllers |
|---|---|

Use Scenario: Powering low-power glucose monitors or pulse oximeters powered by coin-cell or single AA batteries. IC Role / Device Role / Timing Role: Provides clean, regulated 1.5V supply to analog front-end and microcontroller core. Use Value: 50µA quiescent current extends battery life beyond 12 months; 400mV dropout allows operation until battery reaches 1.9V. |

IC Role / Device Role / Timing Role: Supplies stable 1.5V logic rail independent of host USB bus voltage variation (4.75–5.25V). Use Value: ±2% accuracy ensures reliable level-shifting; 58dB PSRR rejects switching noise from upstream DC-DC converters. |
| Wireless Sensor Node MCUs | Industrial Data Acquisition Modules |
|

IC Role / Device Role / Timing Role: Second-stage regulator delivering precise 1.5V to MCU I/O or ADC reference circuitry. Use Value: Low 30mV load regulation (1–300mA) prevents digital noise coupling into sensitive analog measurement paths. |
Use Scenario: Supplying isolated signal-conditioning circuits in 4–20mA loop-powered transmitters. IC Role / Device Role / Timing Role: Generates local 1.5V bias for precision op-amps and voltage references in analog signal chains. Use Value: 50ppm/°C output drift ensures <±0.1% error over -40°C to +85°C industrial temperature range. |
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 |
|---|---|---|---|
| MCP1700-1502E/TO (Microchip) | 250mA max output, 175mV dropout at 250mA, SOT23-3 package, higher IQ (2.5µA) | Lower current capability; better suited for ultra-low-power sensor nodes than high-transient peripherals | Select when <250mA load and sub-3µA quiescent current are mandatory; avoid for 300mA burst loads. |
| TPS73115DBVR (TI) | 300mA output, 120mV dropout at 300mA, SOT23-5 package, integrated enable pin, higher cost | Requires enable control and additional decoupling; superior dropout but larger footprint and BOM complexity | Choose for systems needing active sequencing or tighter dropout (<200mV); not drop-in due to pin count and enable requirement. |
Compared with MCP1700-1502E/TO and TPS73115DBVR, AP130-15RG-7 offers balanced 300mA capability, SC59R's compact 2.9×1.3mm footprint, and proven thermal robustness in cost-sensitive portable designs-without requiring enable logic or premium pricing.

FAQ
What is the minimum input voltage required for AP130-15RG-7 to maintain regulation?
The AP130-15RG-7 requires VIN ≥ (VOUT + VDROP). With VOUT = 1.5V and typical dropout = 400mV, minimum input is 1.9V. At 300mA load and 25°C, regulation is guaranteed down to 1.9V; below that, output drops linearly with input.
Can AP130-15RG-7 be used without an output capacitor?
No. A minimum 10µF ceramic capacitor is mandatory between OUT and GND for stability, as confirmed in the datasheet's Functional Descriptions section. Omitting it risks oscillation, output overshoot, and thermal instability under load transients.
How does the SC59R package differ electrically from SC59 in AP130 variants?
SC59R has reversed pinout (GND/OUT/IN) versus SC59 (IN/OUT/GND), but identical electrical specs, thermal resistance (250°C/W), and footprint. No performance difference exists-only PCB layout orientation changes to accommodate routing constraints.
Is AP130-15RG-7 qualified for automotive applications?
No. The AP130-15RG-7 is specified for industrial temperature range (-40°C to +85°C ambient), not AEC-Q100. Diodes Incorporated does not list it in automotive-grade product families, and its thermal shutdown threshold (+125°C) lacks automotive-grade margin or qualification testing.
