Product details
Overview
AP130-33SAG-7 from Diodes Incorporated is a 300mA fixed-output 3.3V low-dropout linear regulator in SOT23 package, featuring 400mV dropout at full load, ±2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element with no base current draw, thermal shutdown, and fold-back short-circuit protection - designed for battery-powered portable electronics requiring stable, low-noise 3.3V rail generation.
For engineers reviewing the AP130-33SAG-7 datasheet, AP130-33SAG-7 pinout, AP130-33SAG-7 application, or AP130-33SAG-7 equivalent, key selection criteria include dropout voltage under 300mA load, guaranteed 3.3V output tolerance across temperature, thermal resistance (θJA = 200°C/W), and compatibility with 1µF input / 10µF output ceramic capacitors in space-constrained layouts.
Technical Context
The AP130-33SAG-7 employs a PMOS pass transistor architecture enabling zero gate-drive current and inherently low dropout performance. Its internal bandgap reference and error amplifier deliver tight regulation with 30mV load regulation (1–300mA) and 0.1%/V line regulation over 2.7–5.5V input range.
Protection circuitry includes thermal shutdown triggered at ~125°C junction temperature and current-limit activation at 350–450mA, followed by fold-back to ≤300mA short-circuit current. PSRR reaches 58dB at 100Hz, supporting noise-sensitive analog and RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% at 1mA, ensuring reliable logic-level compliance for 3.3V microcontrollers and peripherals. |
| Dropout Voltage | 400mV typ. at 300mA, enabling operation down to 3.7V input while maintaining regulated 3.3V output. |
| Quiescent Current | 50µA typ. at zero load, minimizing standby power loss in battery-backed systems. |
| Load Regulation | ±30mV over 1–300mA load range, reducing voltage sag during dynamic processor or radio transmit bursts. |
| PSRR | 58dB at 100Hz, attenuating switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Resistance θJA | 200°C/W (SOT23), defining maximum power dissipation (≤375mW at 85°C ambient) before thermal shutdown. |
| Short-Circuit Current | 150–300mA fold-back limit, limiting fault power and enabling safe recovery without external current limiting. |
Pinout & Package
SOT23-3L package: compact 2.9mm × 1.3mm surface-mount outline with gull-wing leads; JEDEC MO-178AA compliant; RoHS-compliant green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input power supply connection | Accepts 2.7–5.5V; requires ≥1µF ceramic capacitor to ground for stability and transient response. |
| 2 (OUT) | Regulated 3.3V output | Delivers up to 300mA; requires ≥10µF ceramic capacitor to ground to maintain loop stability and load step response. |
| 3 (GND) | Analog and power ground reference | Must be connected directly to low-impedance PCB ground plane; separates regulation feedback path from high-current return paths. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS Pass Element | Zero gate drive current eliminates base/emitter leakage, enabling ultra-low IQ and eliminating BJT-related thermal drift. |
| Fast Transient Response | Stable with 10µF output cap; recovers within microseconds from 100mA load steps, critical for burst-mode wireless transceivers. |
| Thermal Shutdown + Fold-Back | Prevents latch-up during sustained overload; reduces fault current to safe level, allowing automatic recovery when load normalizes. |
| 2% Output Accuracy | Guaranteed over -40°C to +85°C ambient, ensuring I/O voltage margin compliance for 3.3V SPI, I²C, and UART interfaces. |
| Green Molding Compound | Halogen-free (no Br/Sb), meeting IPC-4101D and JEDEC J-STD-020 reflow requirements for lead-free assembly. |
Applications

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 |
|---|---|---|---|
| AP2202K-3.3TRG1 | Higher IQ (1.2µA), lower output current (150mA), same SOT23-3 package. | Better for ultra-low-power sleep modes but insufficient for 300mA peak loads like Wi-Fi transceivers. | Select when standby current dominates design budget and peak load ≤150mA. |
| MCP1700T-3302E/TT | Lower dropout (178mV @ 250mA), higher accuracy (±0.4%), but larger SOT23-5 package with enable pin. | Requires PCB redesign for 5-pin layout; adds enable control but increases BOM count if unused. | Select when tighter regulation and lower dropout justify extra pin and layout change. |
Compared with AP2202K-3.3TRG1 and MCP1700T-3302E/TT, the AP130-33SAG-7 uniquely balances 300mA drive capability, 50µA IQ, and minimal 3-pin SOT23 footprint - making it optimal for cost- and space-sensitive 3.3V applications where moderate quiescent current is acceptable.

FAQ
Is AP130-33SAG-7 compatible with ceramic output capacitors?
Yes - the AP130-33SAG-7 is explicitly characterized and stabilized with a 10µF X5R/X7R ceramic capacitor on the output, per the datasheet's Typical Application Circuit and Electrical Characteristics test conditions. No ESR requirements apply, unlike older LDOs that needed tantalum or aluminum electrolytics.
What is the minimum input voltage required to maintain 3.3V output at 300mA?
The minimum input voltage is 3.7V: calculated as VOUT + VDROP = 3.3V + 0.4V (typical dropout at 300mA). At 3.7V input, the device sustains full 300mA load while holding output within ±2% tolerance across -40°C to +85°C ambient.
Does AP130-33SAG-7 require an input capacitor?
Yes - a minimum 1µF ceramic capacitor is required between IN and GND, placed as close as possible to the device pins. This stabilizes the input supply against source impedance and prevents oscillation during load transients, as confirmed in the Functional Descriptions section of DS31027 Rev. 8-2.
Can AP130-33SAG-7 be used in automotive applications?
No - the AP130-33SAG-7 is specified for industrial temperature range (-40°C to +85°C ambient), not automotive AEC-Q100 Grade 2 (-40°C to +105°C) or Grade 1 (-40°C to +125°C). Diodes Incorporated does not qualify this part for automotive use, and its thermal shutdown threshold and lifetime reliability data are not validated for under-hood environments.
