Product details
Overview
AP7313-10SRG-7 from Diodes Incorporated is a 150mA, fixed 1.0V output, low dropout linear regulator in SOT23R package with 65µA typical quiescent current, 150mV dropout at full load, and 65dB PSRR at 100Hz - designed for battery-powered portable devices requiring stable low-voltage bias under fast transient loads.
For engineers reviewing the AP7313-10SRG-7 datasheet, AP7313-10SRG-7 pinout, AP7313-10SRG-7 application, or AP7313-10SRG-7 equivalent, key selection criteria include ultra-low IQ across input range (2–6V), stability with 1µF ceramic output capacitor, fast 80µs startup, and integrated thermal shutdown, current limit, and short-circuit protection.
Technical Context
The AP7313-10SRG-7 employs a P-channel MOSFET pass element with bandgap reference and error amplifier to deliver precise 1.0V regulation. Its architecture enables low dropout (150mV typ. @ 150mA) and minimal load-dependent quiescent current variation - maintaining ~65µA from 0mA to 150mA output.
It integrates three independent protection circuits: current limit (~300mA), short-circuit clamp (~50mA), and thermal shutdown at +140°C with 15°C hysteresis. The device achieves fast transient response via optimized internal compensation, enabling stable operation with only 1µF output capacitance and exhibiting <100mV undershoot/overshoot during 0→150mA load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0V ±2% over -40°C to +85°C ambient - ensures reliable core/bias rail for low-voltage logic and sensors. |
| Max Output Current | 150mA continuous - supports single-rail microcontrollers, RF front-ends, and sensor signal chains. |
| Quiescent Current | 65µA typical at 150mA load - extends battery life in always-on wearable and IoT edge nodes. |
| Dropout Voltage | 150mV typical at 150mA - enables operation down to 1.15V input, critical for single-cell Li-ion or alkaline systems. |
| PSRR | 65dB at 100Hz - suppresses low-frequency power supply noise from switching converters feeding the LDO input. |
| Start-up Time | 80µs - allows rapid wake-up from deep sleep without voltage droop in time-sensitive DSP or radio control paths. |
| Stability | Guaranteed with 1µF X7R/X5R ceramic output capacitor - eliminates need for bulky tantalum or electrolytic caps. |
Pinout & Package
SOT23R package: 3-pin, RoHS-compliant, green molding compound, 230°C/W junction-to-ambient thermal resistance, footprint per Diodes Inc. AP02001 pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Top View) | GND | Ground reference for internal circuitry and thermal path - must connect to low-impedance PCB ground plane. |
| 2 (Top View) | OUT | Regulated 1.0V output - requires local 1µF ceramic capacitor to GND within 3mm trace length. |
| 3 (Top View) | IN | Input supply (2–6V) - bypassed with ≥1µF ceramic capacitor to GND to suppress high-frequency noise and ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 65µA across full 0–150mA load range - minimizes standby power loss in battery-gated subsystems. |
| Fast transient response | Controlled undershoot/overshoot during 0→150mA load steps - maintains voltage integrity for GSM/TDMA baseband ICs. |
| Integrated protection | Current limit (~300mA), short-circuit clamp (~50mA), and thermal shutdown (+140°C) - eliminates need for external fault management circuitry. |
| No minimum load requirement | Stable regulation at 0mA output - simplifies design for intermittent-load applications like sensor polling. |
| Low-ESR capacitor compatibility | Stable with 10–200mΩ ESR ceramic capacitors - avoids instability risks associated with high-ESR electrolytics. |
Applications
| Wearable Health Monitors | Bluetooth LE Sensor Nodes |

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-1002E/TT (Microchip) | 100mA max output, 1.8µA IQ, 600mV dropout at 100mA - lower IQ but halved current capability. | Not suitable for 150mA peak loads (e.g., BLE transmit burst); better for micropower sensor bias only. | Select when IQ < 2µA is mandatory and peak load ≤100mA. |
| TPS7A0510PDBVR (TI) | 200mA max output, 25µA IQ, 170mV dropout at 200mA - higher current, slightly higher dropout, tighter VOUT tolerance (±1%). | Supports higher peak loads but requires 2.2µF min. output cap - less board-space efficient than AP7313's 1µF solution. | Select when >150mA headroom or ±1% accuracy is required, accepting larger output capacitor footprint. |
Compared with MCP1700T-1002E/TT and TPS7A0510PDBVR, the AP7313-10SRG-7 uniquely balances 150mA capability, 65µA IQ, 150mV dropout, and 1µF stability - making it optimal for space-constrained, battery-powered systems needing moderate current with ultra-low standby loss.

FAQ
What is the minimum input voltage required for stable 1.0V output at 150mA?
The AP7313-10SRG-7 requires VIN ≥ VOUT + VDropout = 1.0V + 0.15V = 1.15V minimum for full 150mA regulation. However, the recommended operating range starts at 2.0V per datasheet specifications to ensure robust performance across temperature and process variation. Below 2.0V, functionality is not guaranteed.
Can the AP7313-10SRG-7 operate without an output capacitor?
No - an output capacitor is mandatory for stability and transient response. The device is specified and tested with 1µF ceramic (X7R/X5R, 10–200mΩ ESR). Operation without it risks oscillation, overshoot, or failure to regulate. No-load stability does not eliminate the need for the capacitor.
Does the AP7313-10SRG-7 support enable/shutdown control?
No - the AP7313-10SRG-7 has no enable (EN) pin or shutdown mode. It operates continuously when VIN is within 2–6V. For applications requiring on/off control, an external load switch or series FET must be used upstream of the IN pin.
How does thermal shutdown behave under sustained overload?
When junction temperature reaches ~140°C, the output disables; it re-enables once temperature falls to ~125°C. Under sustained overload (e.g., 150mA at VIN=6V on minimal copper), this causes thermal cycling - visible as periodic output dropout. Proper PCB thermal design (2oz copper, recommended pad layout) prevents cycling in normal operation.
