Product details
Overview
AP130-35YL-13 from Diodes Incorporated is a fixed 3.5V, 300mA low-dropout linear regulator in SOT89-3L 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 stable power delivery in space-constrained battery-powered peripherals.
For engineers reviewing the AP130-35YL-13 datasheet, AP130-35YL-13 pinout, AP130-35YL-13 application, or AP130-35YL-13 equivalent, key selection factors include dropout voltage under 300mA load, output accuracy tolerance, thermal resistance (θJA = 100°C/W), and compatibility with 10µF minimum output capacitance for stability.
Technical Context
The AP130-35YL-13 employs a PMOS pass transistor with internal 1.5Ω RON, enabling low dropout and zero gate-drive current. Its bandgap-referenced error amplifier delivers fast transient response and tight load regulation (±40mV over 1–300mA).
Protection circuitry includes fold-back current limiting (150–300mA short-circuit current) and thermal shutdown triggered at junction temperatures exceeding +125°C. Input voltage range is strictly 2.7V to 5.5V, with PSRR of 58dB at 100Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.5V ±2% - ensures stable rail for 3.3V-tolerant logic without external feedback. |
| Max Output Current | 300mA continuous - supports moderate-power peripherals like USB hubs or sensor modules. |
| Dropout Voltage | 400mV typ. at 300mA - enables operation down to 3.9V input while maintaining regulated 3.5V output. |
| Quiescent Current | 50µA typ. at zero load - minimizes standby power loss in always-on battery systems. |
| Line Regulation | 0.1–0.3%/V - maintains output stability across input variations typical in unregulated DC-DC stages. |
| PSRR | 58dB at 100Hz - suppresses ripple from upstream switching regulators feeding the LDO. |
| Thermal Resistance θJA | 100°C/W (SOT89-3L, no heatsink) - defines maximum power dissipation (315mW at ΔT=31.5°C rise) in standard PCB layout. |
Pinout & Package
SOT89-3L package: 3-pin surface-mount, thermally enhanced plastic outline with exposed tab (pin 2 connected to GND for thermal conduction). Dimensions: 4.50mm × 2.48mm × 1.50mm (L×W×H), 0.95mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output node | Delivers fixed 3.5V to load; requires ≥10µF ceramic capacitor to ground for stability. |
| 2 (GND) | Ground reference and thermal pad | Primary return path and main thermal conduction path; must be soldered to large copper pour. |
| 3 (IN) | Unregulated input supply | Accepts 2.7–5.5V input; requires local 1µF bypass capacitor near pin. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS pass element | Eliminates base/gate drive current, enabling ultra-low IQ independent of load. |
| Fold-back current limit | Reduces short-circuit power dissipation to ≤450mW, preventing thermal runaway during fault. |
| Thermal shutdown | Activates at TJ > +125°C and auto-recovers after cooldown-no latch-up or manual reset needed. |
| Green RoHS-compliant packaging | SOT89-3L with halogen-free molding compound (no Br/Sb), meeting Diodes Inc. AP02007 spec. |
Applications
| Battery-Powered Peripherals | PC Card Power Supply |
|---|---|
|

IC Role / Device Role / Timing Role: Primary voltage regulator providing clean 3.5V rail to MCU and RF transceiver. Use Value: 400mV dropout allows >90% usable battery voltage range; 50µA IQ extends shelf life in sleep mode. |
Use Scenario: Regulating 5V bus-derived supply for CD-ROM/DVD drive interface logic on legacy PC add-in cards. IC Role / Device Role / Timing Role: Local point-of-load regulator decoupling noise-sensitive digital I/O buffers. Use Value: 58dB PSRR at 100Hz attenuates switching noise from host 5V DC-DC converter, reducing bit errors. |
| Wireless Communication Module | Industrial Sensor Node |
|
Use Scenario: Supplying 3.5V to sub-GHz transceivers (e.g., TI CC1101) in battery-operated remote sensors. IC Role / Device Role / Timing Role: Stable bias source for RF front-end and crystal oscillator circuitry. Use Value: ±2% output accuracy ensures consistent transmit power and frequency stability across temperature. |
Use Scenario: Powering low-power microcontrollers (e.g., STM32L0) and analog signal chains in wired industrial nodes. IC Role / Device Role / Timing Role: Main system regulator with integrated protection for field-deployed equipment. Use Value: Thermal shutdown and current fold-back prevent damage during accidental output short or ambient overheating. |
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 max output, 175mV dropout at 250mA, 2.5µA IQ - lower current, lower dropout, much lower quiescent current. | Not suitable for 300mA peak loads; better for ultra-low-power IoT endpoints with intermittent transmission. | Select when load current never exceeds 250mA and battery life is prioritized over peak capability. |
| TPS73035DBVR | 200mA max, 120mV dropout at 200mA, 170µA IQ - higher IQ, lower dropout, lower current rating. | Limited to lighter loads; requires tighter input voltage control due to lower dropout margin. | Choose only if board layout allows superior thermal management and load stays below 200mA. |
Compared with MCP1700-3502E/TO and TPS73035DBVR, the AP130-35YL-13 uniquely balances 300mA capability, 400mV dropout, and 50µA IQ in a thermally robust SOT89-3L package-making it optimal for mid-power portable designs where both peak current and standby efficiency matter.

FAQ
What is the minimum output capacitance required for stability with AP130-35YL-13?
The AP130-35YL-13 requires a minimum 10µF ceramic capacitor from OUT to GND for guaranteed stability across all operating conditions. This value is specified in the Functional Descriptions section of DS31027 Rev. 8-2 and validated in typical performance curves. Using less capacitance may cause oscillation or poor transient response.
Can AP130-35YL-13 operate with an input voltage of 3.6V?
Yes-AP130-35YL-13 supports input voltages from 2.7V to 5.5V. At 3.6V input and 300mA load, the 400mV typical dropout leaves 3.2V at the output, which remains within the ±2% (3.43–3.57V) specification only if load is reduced. Full 3.5V regulation at 300mA requires ≥3.9V input.
Is the SOT89-3L package thermally enhanced, and how is heat dissipated?
Yes-the SOT89-3L package features an exposed thermal pad on the underside (connected to pin 2/GND). Heat is conducted through this pad into the PCB copper pour. The datasheet specifies θJA = 100°C/W with no heatsink and standard FR-4 layout, confirming its thermal enhancement over smaller packages like SOT23.
Does AP130-35YL-13 require an input bypass capacitor, and what value is recommended?
Yes-a 1µF ceramic capacitor is required between IN and GND, placed as close as possible to the device pins. This is specified in the Typical Application Circuit and Electrical Characteristics tables of DS31027. It stabilizes the input impedance and prevents oscillation caused by source inductance during load transients.
