Product details

Overview

AP130-30SAG-7 from Diodes Incorporated is a 300mA fixed-output 3.0V low-dropout linear regulator in SOT23 package, featuring 400mV dropout at full load, 50µA quiescent current, ±2% output accuracy, and integrated thermal shutdown and current-limit protection. It serves as a primary voltage regulator for battery-powered peripherals requiring stable 3.0V rail under variable load.

For engineers reviewing the AP130-30SAG-7 datasheet, AP130-30SAG-7 pinout, AP130-30SAG-7 application, or AP130-30SAG-7 equivalent, key selection criteria include dropout performance at 300mA, ground current behavior across input voltage range, PSRR at 100Hz, short-circuit fold-back response, and SOT23 thermal resistance (θ_JA = 200°C/W).

Technical Context

The AP130-30SAG-7 uses a PMOS pass element with 1.5Ω R_ON, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its error amplifier compares feedback from an internal bandgap reference to regulate output precisely at 3.0V.

Protection circuitry includes fold-back current limiting (150–300mA short-circuit current) and thermal shutdown triggered at junction temperatures exceeding +125°C. Load regulation remains within ±40mV from 1mA to 300mA at V_IN = 5V.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±2% - ensures stable logic supply for 3.3V-tolerant I/O without external resistors.
Dropout Voltage	400mV at 300mA - enables operation down to 3.4V input while maintaining regulation, critical for single-cell Li-ion or dual-cell alkaline systems.
Quiescent Current	50µA typical - minimizes standby power loss in always-on battery applications like wireless sensors.
PSRR	58dB at 100Hz - suppresses ripple from noisy switcher outputs or shared DC rails feeding mixed-signal circuits.
Thermal Resistance θ_JA	200°C/W (SOT23) - limits junction temperature rise to ≤60°C at 300mA with minimal PCB copper, suitable for compact layouts.
Current Limit	350–450mA - provides robust fault tolerance without latch-up; fold-back reduces power dissipation during sustained shorts.
Line Regulation	0.1–0.3%/V - maintains output stability despite battery voltage decay from 4.2V to 2.7V.

Pinout & Package

SOT23-3 package (JEDEC TO-236AB), 1.3mm × 2.9mm footprint, 1.0mm height, lead-free and RoHS-compliant. Thermal pad not present; standard 2oz copper layout recommended per AP02001.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	Input Power Supply	Accepts 2.7–5.5V; requires ≥1µF ceramic input capacitor to limit source impedance during load transients.
2 (OUT)	Regulated Output	Delivers 3.0V ±2%; requires ≥10µF low-ESR output capacitor for loop stability and transient response.
3 (GND)	Analog Ground Reference	Low-impedance return path for error amplifier and pass device; must be routed separately from high-current GND traces.

Key Features

Feature	Design Value
PMOS Pass Element	R_ON = 1.5Ω enables 400mV dropout at 300mA while drawing zero gate current-reducing total system IQ.
Fast Transient Response	Stabilizes within 10µs after 100mA step load change-preserves signal integrity in burst-mode RF or MCU wake-up events.
Short-Circuit Fold-Back	Reduces output current to 150–300mA during hard shorts-limits die temperature rise and avoids thermal runaway.
Green Molding Compound	Halogen-free (no Br/Sb) per IEC 61249-2-21-meets environmental compliance for consumer and industrial end equipment.
Thermal Shutdown	Activates at T_J > +125°C and auto-recovers after cooldown-enables safe operation in enclosed enclosures without heatsinks.

Applications

Wireless Sensor Node

USB Peripheral Controller

Use Scenario: Sub-1W IoT sensor node powered by CR2032 or single Li-ion cell, operating intermittently with BLE radio bursts.

IC Role / Device Role / Timing Role: Primary 3.0V LDO supplying MCU core, BLE SoC I/O, and analog sensor interface.

Use Value: 50µA quiescent current extends shelf life beyond 5 years; 400mV dropout allows full 3.0V regulation until battery reaches 3.4V.

Use Scenario: External USB 2.0 hub or card reader with embedded microcontroller and level-shifting logic.

IC Role / Device Role / Timing Role: Local 3.0V rail generator for USB PHY termination, EEPROM, and status LEDs.

Use Value: 58dB PSRR at 100Hz suppresses switching noise from upstream 5V DC-DC converter, preventing USB packet errors.

Industrial Data Logger

POS Terminal Interface Module

Use Scenario: Battery-backed data acquisition module logging temperature/humidity via I²C sensors in remote locations.

IC Role / Device Role / Timing Role: Stable 3.0V supply for precision ADC reference and real-time clock backup domain.

Use Value: ±2% output accuracy and <150ppm/°C tempco ensure consistent measurement calibration across –40°C to +85°C ambient.

Use Scenario: Compact payment terminal add-on board handling magnetic stripe reader, buzzer, and LED indicators.

IC Role / Device Role / Timing Role: Dedicated 3.0V rail isolating noise-sensitive magstripe decoder from shared 5V system bus.

Use Value: Fold-back current limiting prevents latch-up during ESD events on exposed card slot, improving field reliability.

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
MCP1700T-3002E/MB	250mA rating, 175mV dropout at 250mA, 1.8µA IQ - lower current capacity and significantly lower quiescent current.	Limited to sub-250mA loads; better suited for ultra-low-power sleep modes but cannot sustain 300mA continuous.	Select when peak load ≤250mA and standby IQ <20µA is mandatory; avoid if full 300mA capability required.
TPS73030DBVR	200mA rating, 120mV dropout at 200mA, 330µA IQ - higher IQ and lower current, but superior PSRR (65dB @100Hz).	Higher noise rejection but insufficient current headroom for 300mA bursts; requires derating in thermally constrained designs.	Choose only if PSRR >60dB is prioritized over output current and IQ; verify thermal margin at 200mA max.

Compared with MCP1700T-3002E/MB and TPS73030DBVR, the AP130-30SAG-7 uniquely balances 300mA delivery, 400mV dropout, and 50µA IQ in SOT23-making it optimal for cost-sensitive, medium-current portable applications where full-load capability and low standby loss are both essential.

FAQ

What is the minimum input voltage required to maintain 3.0V output at 300mA load?

The AP130-30SAG-7 requires a minimum input voltage of 3.4V to sustain 3.0V output at 300mA, based on its typical 400mV dropout voltage. At lower input voltages, output regulation degrades; operation below 2.7V input is outside absolute maximum ratings and not functional.

Can AP130-30SAG-7 replace AP130-30WL-7 in the same PCB layout?

No-AP130-30SAG-7 uses SOT23-3 (pin 1=IN, 2=OUT, 3=GND), while AP130-30WL-7 uses SC59 (pin 1=IN, 2=OUT, 3=GND) with different pad dimensions and thermal characteristics. The footprints are not interchangeable; redesign of solder mask and copper pour is required.

Does AP130-30SAG-7 require an external bypass capacitor on the IN pin?

Yes-a minimum 1µF ceramic capacitor is required between IN and GND, placed as close as possible to the device. This stabilizes the input source impedance and prevents oscillation during fast load transients, as specified in the functional description section of DS31027 Rev. 8-2.

Is AP130-30SAG-7 qualified for automotive applications?

No-AP130-30SAG-7 is rated for industrial temperature range (–40°C to +85°C ambient) and lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature testing. It is intended for commercial and industrial equipment, not automotive ECUs or infotainment systems.
