Product details
Overview
AP7313-10SAG-7 from Diodes Incorporated is a 150mA fixed-output (1.0V) low dropout linear regulator in SOT23 package, featuring 65µA quiescent current, 150mV typical dropout at full load, and 65dB PSRR at 100Hz. It delivers stable voltage to ultra-low-power circuits such as battery-powered microcontrollers and sensor nodes in portable electronics.
For engineers reviewing the AP7313-10SAG-7 datasheet, AP7313-10SAG-7 pinout, AP7313-10SAG-7 application, or AP7313-10SAG-7 equivalent, key selection criteria include input voltage range (2–6V), no-load stability, fast 80µs start-up time, and compatibility with 1µF ceramic output capacitors - all critical for energy-constrained embedded designs.
Technical Context
The AP7313-10SAG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry (current limit, short-circuit, thermal shutdown). Its architecture enables regulation without minimum load and supports rapid transient response due to optimized internal compensation.
It operates across -40°C to +85°C ambient, maintains ±2% output accuracy over temperature and load, and achieves 0.01–0.20%/V line regulation. The device's low ESR capacitor compatibility and absence of external compensation simplify PCB layout for space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% over -40°C to +85°C - ensures precise core voltage for 1.0V logic domains. |
| Max Output Current | 150mA continuous - sufficient for low-power MCUs, sensors, and RF transceivers. |
| Quiescent Current | 65µA typical at 150mA load - minimizes standby power loss in always-on battery systems. |
| Dropout Voltage | 150mV typical at 150mA - enables operation down to VIN = 1.15V, extending battery runtime. |
| PSRR | 65dB at 100Hz - suppresses low-frequency supply noise from switching regulators or shared rails. |
| Start-up Time | 80µs - allows rapid wake-up from deep sleep without voltage droop on sensitive loads. |
| Stability | Guaranteed with 1µF X7R/X5R ceramic output capacitor - eliminates need for bulkier tantalum or electrolytic caps. |
Pinout & Package
AP7313-10SAG-7 is housed in a RoHS-compliant, lead-free SOT23-3 package (2.92 × 1.3 × 1.0 mm), with "Green" molding compound and standard JEDEC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2–6V DC; requires ≥1µF ceramic bypass to GND for noise rejection and stability. |
| 2 (OUT) | Regulated output | Delivers fixed 1.0V; connects directly to load and 1µF ceramic capacitor to GND. |
| 3 (GND) | Ground reference | Common return path for IN and OUT; must be low-impedance with short, wide PCB traces. |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Maintains regulation and stability at 0mA output - ideal for intermittent-sensing applications. |
| Fast transient response | Controls overshoot/undershoot during 0→150mA load steps - protects DSP/GSM baseband ICs from glitch-induced reset. |
| Integrated protection | Current limit (~300mA), short-circuit clamp (~50mA), and thermal shutdown (140°C trip) - eliminates need for external fault management. |
| Ultra-low IQ across input range | 65µA typical from VIN = 2V to 6V - preserves battery capacity regardless of cell voltage decay. |
Applications
| Wearable Health Monitors | IoT Edge Sensor Nodes |

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 |
|---|---|---|---|
| MCP1700-1002E/TO | 100mA max output, 2.0µA IQ, SOT23-3 - lower current, far lower quiescent current. | Suitable only for sub-100mA loads; insufficient for 150mA GSM transmit bursts. | Select when load current ≤100mA and nanoamp-level standby IQ is mandatory. |
| TPS7A0510PDBVR | 200mA max output, 25µA IQ, SOT23-5 - higher current, lower IQ, but 5-pin package adds routing complexity. | Requires EN pin control and separate bypass caps; not drop-in compatible with 3-pin layout. | Choose when >150mA headroom and ultra-low IQ are needed, and board redesign is acceptable. |
Compared with MCP1700-1002E/TO and TPS7A0510PDBVR, AP7313-10SAG-7 uniquely balances 150mA capability, 65µA IQ, and true 3-pin simplicity - making it optimal for cost-sensitive, space-constrained portable designs requiring no minimum load and fast transient response.

FAQ
Is AP7313-10SAG-7 stable with a 1µF ceramic output capacitor?
Yes. The AP7313-10SAG-7 is explicitly characterized and guaranteed stable with a 1µF X7R or X5R ceramic capacitor (ESR 10–200mΩ). This eliminates the need for larger or higher-ESR capacitors, reducing bill-of-materials cost and PCB area while maintaining fast transient response and low output ripple.
What is the maximum input voltage for AP7313-10SAG-7?
The absolute maximum input voltage is 7V, but the recommended operating range is 2V to 6V. Operation above 6V risks exceeding absolute maximum ratings under transient conditions and may accelerate parametric degradation over temperature and lifetime.
Does AP7313-10SAG-7 require an input capacitor?
Yes. A minimum 1µF ceramic capacitor between IN and GND is required for input decoupling and stability. It must be placed as close as possible to the IN and GND pins using short, wide traces to minimize inductance and ensure reliable operation under fast line transients.
Can AP7313-10SAG-7 operate without any load connected to the output?
Yes. The AP7313-10SAG-7 is designed for no-load stability and maintains regulation and low quiescent current (65µA) even with zero output current. This makes it suitable for systems with intermittent or duty-cycled loads, such as sensor wake-up architectures.
