Product details
Overview
AP7313-30SRG-7 from Diodes Incorporated is a 150mA, fixed 3.0V output, low dropout linear regulator in SOT23R package, featuring 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 AP7313-30SRG-7 datasheet, AP7313-30SRG-7 pinout, AP7313-30SRG-7 application, or AP7313-30SRG-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 AP7313-30SRG-7 integrates a PMOS pass element, bandgap reference, error amplifier, and protection circuitry in a single-die architecture. Its low-dropout design enables operation with only 150mV headroom at 150mA, supporting efficient regulation down to 2.0V input while maintaining ±2% output accuracy over –40°C to +85°C ambient.
It delivers fast transient response to load steps from 1mA to 150mA with minimal overshoot/undershoot, enabled by internal compensation optimized for 1µF–4.7µF X7R/X5R ceramic output capacitors. PSRR remains ≥65dB at 100Hz and >40dB up to 100kHz, making it suitable for noise-sensitive analog and RF supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±2% - ensures precise biasing for 3.3V-tolerant I/O or core logic without external feedback. |
| Max Output Current | 150mA continuous - sufficient for microcontrollers, sensors, and interface ICs in space-constrained portable designs. |
| Quiescent Current | 65µA typical at full load - extends battery life in always-on or low-duty-cycle applications like remote controls or wearables. |
| Dropout Voltage | 150mV typical at 150mA - allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline (3.0V nominal) without brownout. |
| PSRR | 65dB at 100Hz - suppresses low-frequency ripple from switching converters or noisy DC-DC stages feeding the LDO input. |
| Start-up Time | 80µs - enables rapid power sequencing and wake-from-standby in GSM/TDMA baseband systems with burst-mode loads. |
| Thermal Shutdown | 140°C threshold with 15°C hysteresis - provides self-recovery protection under sustained overload or poor PCB thermal layout. |
Pinout & Package
SOT23R package: 3-pin, RoHS-compliant, green molding compound, 230°C/W junction-to-ambient thermal resistance, footprint per Diodes AP02001 recommended pad layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | Return path for all internal circuits; must be connected to low-impedance system ground plane to ensure stability and EMI control. |
| 2 (OUT) | Regulated output | Delivers fixed 3.0V to load; requires 1µF ceramic capacitor placed adjacent to pin for transient response and stability. |
| 3 (IN) | Input supply | Accepts 2–6V unregulated input; bypassed with ≥1µF ceramic capacitor close to pin to suppress high-frequency noise and supply glitches. |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Maintains regulation and stability at 0mA output - eliminates need for dummy load resistors in sleep-mode applications. |
| Stable with 1µF ceramic output cap | Reduces BOM count and board area vs. traditional LDOs requiring ≥10µF tantalum - lowers cost and improves reliability. |
| Fast line/load transient response | Controls output deviation within ±30mV during 1mA↔150mA load steps - prevents logic errors in DSP or MCU cores during burst activity. |
| Integrated short-circuit protection | Limits output current to ~50mA when VOUT < 200mV - prevents thermal runaway during accidental GND shorts on PCB or connectors. |
| Ultra-low IQ over full input range | 65µA maintained from 2V to 6V input - ensures consistent battery runtime regardless of cell voltage decay in primary battery systems. |
Applications
| Portable Medical Sensors | GSM Baseband Power Supply |

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 |
|---|---|---|---|
| MCP1700-3002E/TO | 3.0V fixed, 250mA, 1.6µA IQ, SOT23 - lower IQ but higher dropout (600mV @ 250mA). | Better for ultra-long-life coin-cell applications; less suitable for single-cell Li-ion due to higher dropout. | Select when standby current dominates lifetime budget and input voltage margin exceeds 600mV. |
| TPS78030QDSERQ1 | 3.0V fixed, 150mA, 500nA IQ, enable pin, SOT23 - automotive-grade, much lower IQ but slower 150µs startup. | Qualified for automotive infotainment modules; lacks fast transient response needed for GSM burst loads. | Select for AEC-Q100-compliant designs where nanoscale IQ outweighs transient performance requirements. |
Compared with MCP1700-3002E/TO and TPS78030QDSERQ1, the AP7313-30SRG-7 uniquely balances ultra-fast 80µs startup, robust 65dB PSRR, and 65µA IQ in an industrial-temperature-rated SOT23R package-making it optimal for cost-sensitive portable electronics needing both efficiency and responsiveness.

FAQ
What is the maximum input voltage rating for AP7313-30SRG-7?
The absolute maximum input voltage is 7V, but the recommended operating range is 2V to 6V. Exceeding 6V risks violating safe operating area limits and may trigger thermal shutdown or reduce long-term reliability-even if within absolute max ratings-due to increased power dissipation in the pass element.
Can AP7313-30SRG-7 operate without an output capacitor?
No. While the device remains stable with no load, an output capacitor is mandatory for transient response and loop stability. The datasheet specifies 1µF–4.7µF ceramic (X7R/X5R) with 10–200mΩ ESR; omitting it causes oscillation, overshoot, or failure to regulate under dynamic load conditions.
How does the SOT23R package differ electrically from SOT23 for AP7313?
SOT23R has identical electrical specifications but different pinout: IN is pin 3, GND is pin 1, and OUT is pin 2 (vs. IN=1, OUT=2, GND=3 in SOT23). Thermal resistance is higher (230°C/W vs. 207°C/W), requiring slightly more conservative power derating in thermally constrained layouts.
Is AP7313-30SRG-7 qualified for automotive applications?
No. It is rated for industrial temperature range (–40°C to +85°C ambient), not automotive AEC-Q100. For automotive use, Diodes offers the AP7313Q series with extended temperature range (–40°C to +125°C) and qualification testing-AP7313-30SRG-7 lacks those stress validations and screening.
