Product details
Overview
AP7313-20SAG-7 from Diodes Incorporated is a 150mA, fixed 2.0V output, low dropout linear regulator in SOT23 package with 65µA quiescent current, 150mV typical dropout at full load, and 65dB PSRR at 100Hz-designed for battery-powered portable devices requiring stable low-power voltage regulation.
For engineers reviewing the AP7313-20SAG-7 datasheet, AP7313-20SAG-7 pinout, AP7313-20SAG-7 application, or AP7313-20SAG-7 equivalent, key selection criteria include ultra-low IQ across load range, fast 80µs startup, stability with 1µF ceramic output capacitor, and built-in thermal shutdown, current limit, and short-circuit protection.
Technical Context
The AP7313-20SAG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry to deliver precise 2.0V output with ±2% accuracy over –40°C to +85°C ambient. Its low 150mV dropout enables operation down to VIN = 2.15V while sustaining 150mA load.
Designed for transient-sensitive loads, it achieves fast line/load response via optimized internal compensation-verified by 50µs/div transient waveforms-and maintains stability with 1µF–4.7µF X7R/X5R ceramic capacitors (ESR 10–200mΩ), eliminating minimum load requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0V ±2% over –40°C to +85°C; ensures stable core logic supply for 2.0V I/O domains. |
| Max Output Current | 150mA continuous; supports microcontrollers, sensors, and RF front-ends in compact portable systems. |
| Quiescent Current | 65µA typical at 150mA load; extends battery life in always-on monitoring circuits. |
| Dropout Voltage | 150mV typical at 150mA; allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline (2.4V min). |
| PSRR | 65dB at 100Hz; suppresses power supply ripple from noisy DC-DC converters feeding sensitive analog circuitry. |
| Start-up Time | 80µs typical; enables rapid wake-from-sleep in duty-cycled GSM/Bluetooth baseband ICs. |
| Thermal Shutdown | Triggers at 140°C junction temperature with 15°C hysteresis; prevents permanent damage during sustained overload. |
Pinout & Package
AP7313-20SAG-7 uses the SOT23-3 package (2.92mm × 1.3mm × 1.0mm), RoHS-compliant, green molding compound, with lead-free finish. Pin assignment follows standard SOT23 top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0V–6.0V input; requires ≥1µF ceramic bypass capacitor placed adjacent to pin for noise immunity. |
| 2 (OUT) | Regulated output | Delivers stable 2.0V; connects directly to load with minimal trace length to preserve transient response. |
| 3 (GND) | Power ground reference | Common return path for IN and OUT; must tie to low-impedance PCB ground plane to minimize thermal resistance (θJA = 207°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 65µA across full 0–150mA load range-reduces standby power loss in battery-backed real-time clocks. |
| Fast transient response | Stable 0→150mA load step without >2% overshoot/undershoot-critical for GSM TDMA burst-mode baseband supplies. |
| No minimum load requirement | Remains regulated and stable at 0mA output-enables use in intermittent-sensing IoT nodes with deep sleep modes. |
| Integrated protection | Current limit (~300mA), short-circuit clamp (~50mA), and thermal shutdown (140°C) prevent field failures without external components. |
| Small-footprint stability | Operates with 1µF ceramic output capacitor-reduces BOM count and PCB area vs. legacy LDOs needing ≥10µF tantalum. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2002E/TT (Microchip) | 250mA rating, 1.6µA IQ (lower), but 300mV dropout at 250mA; SOT23-3 pinout identical. | Better for ultra-low-IQ always-on circuits; higher dropout limits use with <2.3V inputs. | Select when IQ <2µA is critical and load ≤250mA; verify thermal margin at full load. |
| Torex XC6206P202MR-G (Torex) | 150mA rating, 1µA IQ, 350mV dropout at 150mA; same SOT23-3 footprint but different pinout (IN/GND/OUT vs IN/OUT/GND). | Superior IQ for decades-long battery life; pinout mismatch requires PCB redesign. | Choose for extreme low-power logging; confirm layout compatibility before migration. |
Compared with MCP1700T-2002E/TT and XC6206P202MR-G, the AP7313-20SAG-7 offers optimal balance of ultra-low IQ (65µA), low dropout (150mV), and drop-in SOT23-3 compatibility-making it ideal for cost-sensitive, space-constrained portable designs where 2.0V rail stability under dynamic load is essential.

FAQ
What is the maximum input voltage for AP7313-20SAG-7?
The absolute maximum input voltage is 7V, but the recommended operating range is 2.0V to 6.0V. Exceeding 6.0V risks exceeding the device's safe operating area, especially under load, due to power dissipation limits in the SOT23 package (600mW max). Operation above 6.0V may trigger thermal shutdown or degrade long-term reliability.
Can AP7313-20SAG-7 operate without an output capacitor?
No-while the device remains stable with no minimum load current, an output capacitor is mandatory for stability and transient performance. The datasheet specifies 1µF to 4.7µF ceramic (X7R/X5R) with 10–200mΩ ESR. Omitting it causes oscillation, excessive overshoot/undershoot, and potential damage to downstream circuitry during load steps.
Is AP7313-20SAG-7 compatible with ceramic capacitors having ESR below 10mΩ?
Yes, but caution is required: the AP7313 is optimized for 10–200mΩ ESR. Capacitors with ESR <10mΩ (e.g., some high-grade X7R or C0G types) may reduce phase margin and cause instability. If using ultra-low-ESR ceramics, verify stability with load transients and consider adding a small series resistor (e.g., 5–10Ω) to restore damping.
Does AP7313-20SAG-7 support enable/shutdown control?
No-the AP7313-20SAG-7 lacks an enable pin and operates continuously when input voltage is applied within specification. It cannot be externally disabled. For applications requiring controlled power sequencing, an external MOSFET switch on the input rail or a variant with EN functionality (e.g., AP7315) must be used instead.
