Product details
Overview
AP7313-30SAG-7 from Diodes Incorporated is a 150mA fixed-output (3.0V) low dropout linear regulator in SOT23 package, featuring 65µA quiescent current, 150mV typical dropout at full load, and 65dB PSRR at 100Hz - optimized for battery-powered portable devices requiring stable low-power voltage regulation.
For engineers reviewing the AP7313-30SAG-7 datasheet, AP7313-30SAG-7 pinout, AP7313-30SAG-7 application, or AP7313-30SAG-7 equivalent, key selection criteria include ultra-low IQ across input range (2–6V), fast 80µs startup, stability with 1µF ceramic output capacitor, and integrated thermal shutdown, current limit, and short-circuit protection.
Technical Context
The AP7313-30SAG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry in a single-die architecture. Its low dropout (150mV @ 150mA) enables operation down to VIN = 3.15V while maintaining 3.0V output, and its 65µA IQ remains stable across 0–150mA load and 2–6V input.
Designed for transient-sensitive loads, it delivers <±0.6% load regulation and exhibits fast line/load transient response with minimal overshoot/undershoot - verified at 3.0V output under 150mA step changes. PSRR reaches 65dB at 100Hz and maintains >45dB up to 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% over -40°C to +85°C ambient - ensures precise rail generation for 3.0V logic and analog circuits. |
| 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 or duty-cycled applications like IoT sensors. |
| Dropout Voltage | 150mV typical at 150mA - allows operation from single-cell Li-ion (3.0–4.2V) or two-cell alkaline (2.4–3.2V) sources. |
| PSRR | 65dB at 100Hz - suppresses low-frequency power supply noise from switching regulators or noisy DC-DC stages. |
| Startup Time | 80µs - enables rapid wake-up from deep-sleep modes without compromising system responsiveness. |
| Capacitor Stability | Stable with 1µF X7R/X5R ceramic output capacitor - reduces BOM count and PCB area vs. larger electrolytic solutions. |
Pinout & Package
SOT23-3 package (2.92mm × 1.3mm × 1.0mm), RoHS-compliant "Green" molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2–6V DC; requires ≥1µF ceramic bypass to GND close to pin for noise immunity and stability. |
| OUT (Pin 2) | Regulated output | Delivers stable 3.0V; connects to 1µF ceramic capacitor to GND for fast transient response and low ripple. |
| GND (Pin 3) | Ground reference | Common return path for IN and OUT; must be low-impedance with wide copper trace and direct connection to power plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 65µA across full 0–150mA load and 2–6V input range - minimizes standby power loss in battery-critical designs. |
| Fast transient response | Controlled undershoot/overshoot during 0→150mA load steps - sustains voltage integrity for GSM/TDMA baseband ICs. |
| Integrated protection | Thermal shutdown (140°C), current limit (~300mA), and short-circuit clamp (~50mA) - eliminates need for external fault management. |
| No minimum load requirement | Stable regulation at 0mA output - simplifies design for intermittent-load applications like sensor wake-up circuits. |
Applications
| Wireless Sensor Nodes | GSM Baseband Power |
|---|---|
|
Use Scenario: Sub-1W IoT sensor node powered by coin cell or small LiPo, waking every 30s to sample and transmit data. IC Role / Device Role / Timing Role: Primary 3.0V LDO supplying MCU, RF transceiver, and analog sensor interface. Use Value: 65µA IQ extends coin cell life beyond 2 years; 80µs startup enables sub-millisecond wake-up latency. |
Use Scenario: TDMA-based GSM handset baseband section requiring rapid load transitions between transmit/receive bursts. IC Role / Device Role / Timing Role: Local 3.0V rail for DSP and modem core, responding to 100µA ↔ 150mA load steps within 50µs. Use Value: Fast transient response prevents voltage droop below 2.94V (–2%), avoiding digital reset or bit errors. |
| Portable Medical Monitors | USB-Powered Peripherals |
|
Use Scenario: Handheld ECG or pulse oximeter operating from single-cell Li-ion with strict battery runtime targets. IC Role / Device Role / Timing Role: Main 3.0V supply for analog front-end, ADC, and Bluetooth LE radio. Use Value: 150mV dropout allows >3.5 hours runtime at 150mA peak draw; thermal shutdown prevents overheating during extended use. |
Use Scenario: USB 2.0 hub or card reader drawing power from 5V USB bus, requiring clean 3.0V for logic and interface ICs. IC Role / Device Role / Timing Role: Post-regulator converting noisy 5V USB to low-noise 3.0V for USB PHY and controller. Use Value: 65dB PSRR at 100Hz attenuates USB switcher ripple; 1µF ceramic compatibility reduces solution size and cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/MB | 300mA rating, 1.6µA IQ, but 350mV dropout at 250mA - higher IQ headroom but lower current capability and worse dropout. | Preferred for ultra-low-IQ battery-only systems with <100mA loads; unsuitable for 150mA burst loads due to current limit. | Select when IQ <2µA is mandatory and peak load ≤100mA; avoid if 150mA sustained or low-VIN operation required. |
| TPS70630DBVR | 150mA, 1.8µA IQ, 200mV dropout at 150mA, but requires 2.2µF min output capacitance - higher ESR tolerance but larger footprint. | Better for industrial temperature range (–40°C to 125°C), but slower 500µs startup limits use in fast-wake systems. | Select for extended temperature or high-reliability industrial use; avoid when 80µs startup or 1µF capacitor constraint applies. |
Compared with MCP1700T-3002E/MB and TPS70630DBVR, the AP7313-30SAG-7 uniquely balances 65µA IQ, 150mV dropout, 80µs startup, and 1µF stability - making it optimal for space-constrained, battery-powered portable designs demanding both efficiency and responsiveness.

FAQ
What is the minimum input voltage required for AP7313-30SAG-7 to maintain regulation at 150mA?
The AP7313-30SAG-7 requires VIN ≥ VOUT + VDropout = 3.0V + 0.15V = 3.15V to sustain regulation at 150mA. At 25°C, typical dropout is 150mV; maximum specified dropout is 300mV, so VIN ≥ 3.3V ensures margin across temperature and process variation.
Can AP7313-30SAG-7 operate without an output capacitor?
No - an output capacitor is mandatory for stability and transient response. The device is designed for 1µF to 4.7µF ceramic capacitors with 10–200mΩ ESR. Operation without COUT risks oscillation, excessive overshoot, and failure to regulate under load transients.
Does AP7313-30SAG-7 require a minimum load current to remain stable?
No - the AP7313-30SAG-7 is stable with zero load current. Electrical characteristics confirm regulation is maintained from 0mA to 150mA, and the datasheet explicitly states "no minimum load is required to keep the device stable."
How does the thermal shutdown behave under sustained overload conditions?
When junction temperature reaches ~140°C, thermal shutdown disables the output. After cooling to ~125°C (15°C hysteresis), the regulator automatically resumes operation. Under continuous overload, this causes on/off cycling - limiting average power dissipation and preventing permanent damage.
