Product details

Overview

AP130-35YRG-13 from Diodes Incorporated is a fixed-output 3.5V, 300mA low-dropout linear regulator in SOT89R-3L package with 400mV dropout at full load, 2% output accuracy, and 50µA quiescent current. It integrates PMOS pass element, thermal shutdown, and current-limit protection for battery-powered peripherals and embedded I/O rails.

For engineers reviewing the AP130-35YRG-13 datasheet, AP130-35YRG-13 pinout, AP130-35YRG-13 application, or AP130-35YRG-13 equivalent, key selection criteria include dropout voltage under 300mA load, ±2% VOUT tolerance at 25°C, thermal resistance of 23°C/W (junction-to-case), and compatibility with 10µF minimum output capacitance for stability.

Technical Context

The AP130-35YRG-13 uses a PMOS pass transistor with 1.5Ω R_ON, eliminating base drive current and enabling ultra-low quiescent current (50µA typ). Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (≤40mV over 1–300mA).

Internal protection includes fold-back short-circuit current limiting (150–300mA) and thermal shutdown triggered above +125°C junction temperature. The device operates across −40°C to +85°C ambient with input voltage range 2.7V–5.5V and requires no external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.5V ±2% at 1mA, ensuring stable I/O rail for 3.3V-tolerant logic with margin
Dropout Voltage	400mV max at 300mA, enabling operation down to 3.9V input for single-cell Li-ion or 4.2V supply
Quiescent Current	50µA typical at zero load, minimizing standby power loss in always-on battery systems
Load Regulation	≤40mV over 1–300mA load, maintaining voltage integrity during processor burst activity
PSRR	58dB at 100Hz, suppressing ripple from noisy DC-DC converters upstream of LDO
Thermal Resistance θ_JA	100°C/W (SOT89R-3L, no heatsink), supporting continuous 300mA output at ≤+65°C ambient
Protection Features	Current limit (350–450mA), thermal shutdown, and short-circuit fold-back prevent latch-up or damage

Pinout & Package

SOT89R-3L package: 3-pin surface-mount, exposed thermal pad (pin 2), 1.5mm pitch, 4.5mm × 2.5mm footprint, 1.9mm height. Optimized for high-power dissipation without heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1: GND	Ground reference and thermal path	Primary return for error amp and pass transistor; connects to PCB thermal pad for θ_JA=100°C/W
2: IN	Input power supply connection	Accepts 2.7–5.5V; requires ≥1µF ceramic input capacitor near pin for transient immunity
3: OUT	Regulated output voltage node	Delivers 3.5V ±2%; requires ≥10µF low-ESR output capacitor for loop stability

Key Features

Feature	Design Value
PMOS Pass Element	R_ON = 1.5Ω enables 400mV dropout at 300mA while drawing zero gate current
Low Quiescent Current	50µA typical from 0–300mA load, critical for multi-week battery life in IoT sensors
Fast Transient Response	Stabilizes within 10µs after 100mA step load change, preventing brown-out in microcontroller cores
Integrated Protection	Thermal shutdown + fold-back current limit prevent failure during sustained overload or short circuit
Green Packaging	RoHS-compliant, halogen-free molding compound (no Br/Sb), meeting IPC-1752A environmental standards

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
MCP1700-3502E/TO	250mA rated, 175mV dropout at 250mA, 2.5µA I_Q, TO-92 package	Limited to lower current; TO-92 unsuitable for automated SMT assembly	Select when ultra-low I_Q dominates over output current capability and through-hole mounting is acceptable
TPS73035DBVR	200mA rated, 120mV dropout at 200mA, 220µA I_Q, SOT-23-5 package	Lower current rating and higher quiescent current; includes enable pin not present on AP130	Choose when enable functionality and tighter dropout are required, accepting reduced output current and higher standby power

Compared with MCP1700-3502E/TO and TPS73035DBVR, the AP130-35YRG-13 delivers 50% higher output current (300mA vs. 250/200mA), 20× lower quiescent current than TPS73035DBVR, and SMT-compatible SOT89R-3L packaging-making it optimal for space-constrained, high-current, battery-sensitive designs.

FAQ

What is the minimum output capacitance required for stability with AP130-35YRG-13?

The AP130-35YRG-13 requires a minimum 10µF low-ESR ceramic or tantalum capacitor from OUT to GND for guaranteed stability across all operating conditions. Using less capacitance may cause oscillation or poor transient response, especially under heavy load steps. The datasheet specifies this value based on phase-margin testing with standard 10µF/6.3V X5R ceramics.

Does AP130-35YRG-13 support reverse-voltage protection?

No, the AP130-35YRG-13 does not include reverse-voltage protection. Applying reverse polarity to the IN or OUT pins can damage the internal PMOS pass transistor and bandgap circuitry. External protection-such as a series Schottky diode on the input-is required if system-level reverse-voltage exposure is possible.

Can AP130-35YRG-13 operate with an input voltage below 2.7V?

No. The absolute minimum input voltage is 2.7V per the Recommended Operating Conditions table. Operation below this threshold risks improper regulation, increased dropout, or complete shutdown. At 3.5V output, the lowest functional input is 3.9V (3.5V + 400mV dropout), making 2.7V a hard limit only for lower-output variants-not applicable to this 3.5V version.

Is the SOT89R-3L package thermally enhanced compared to standard SOT89-3L?

Yes. The SOT89R-3L has reversed pinout (GND-IN-OUT vs. OUT-GND-IN) but identical thermal performance: both deliver θ_JA = 100°C/W and θ_JC = 23°C/W under the same board layout. The "R" suffix denotes pinout reversal for routing flexibility-not improved thermal metrics-and shares identical outline dimensions and thermal pad structure.
